I would like to trigger a light to come on when the actuator is fully extended. Is this possible?

@ServoCity 6 жыл бұрын

Hi David, there are various ways you could go about it. For example you could use a limit switch ( www.servocity.com/electronics/components/switches/limit-switches ) that is physically engaged to turn on the light. Or you if you are using something like an Arduino or Raspberry Pi with a servo hat you could use a linear servo ( www.servocity.com/servos/linear-servos ) and a PWM switch ( www.servocity.com/electronics/components/switches/pwm-switches ) and send two PWM signals, one to control the linear servo and one to turn on the light via the PWM switch. You could also use a PWM switch with a Y-harness and linear servo to run them both off of the same PWM signal (like from an RC receiver or Arduino, Raspbery Pi etc) but the light would turn on the entire time the servo is extending and not just at full extension. Let us know if you have any other questions tech@servocity.com.

I have little knowledge of anything to do with servos and could really use a hand figuring out what i need to do what i need to do. Im trying to make an exoskeletal arm brace/ elbow joint for my mum who suffered from arthritis and had many failed attempts at replacing the joint. She now has no elbow or bone 8 inches either side of where the elbow should be. Ive figured out the rigging now im stuck on how to wire up an actuator to extend and hold in place with one button and retract and hold in place when released with another. This is a long shot and im sure youre very busy but any push in the right direction would be amazing! Thanks for your time. Karl :)

Dear Servo City, that is very helpful video, many thanks!! I have one question though, is the any way to vary the output force of the actuator?

@ServoCity 7 жыл бұрын

The output force can be varied by changing the voltage or limiting the current supplied to the motor. If you want to have even more control there are force sensors available that could be used in conjunction with a motor controller as a closed loop system. Please let us know if you have any other questions tech@servocity.com

Yes, a PWM signal will tell the linear servo exactly what position it needs to be at (just like a normal servo). On a servo lead the Red wire is + the black wire is - and the yellow wire is signal.

I bought an actuator for my boat trim motor and it lasted about 3 weeks before it died. I made sure it was water proof and then I also sprayed it with water proofing. So that is one thing you forget to mention. It had much more dynamic and static load rating than I needed and was the correct voltage. It was slow but I would rather slow than not enough lift. Anyway, I would be interested to know what went wrong. The company had a 30 day return but by the time I was able to install I really only got about 3 weeks out of it and maybe had to lift the motor 8 times during that period. Can you comment on what may have/could have gone wrong ?

@greengeckodesign 7 жыл бұрын

The threaded rod (lead screw) gets rotated, it has a lead screw nut which moves up and down along the lead screw as the lead screw rotates.

@AztecWarrior69 4 жыл бұрын

First it's not up and down. It's in / out or extend / retract. Next the screw rotates, it doesn't move in or out. The lead screw nut is what travels along the lead screw and Push Rod / Extension Tube is attached to that nut. The gears that drive the lead screw are a combination of a worm drive/screw that drives the rest of the spur gears. OOPs My apologies. The one he is showing here does not use a worm gear. It is just a set of spur gears.

A couple questions! What is the noise rating on the servo? Also, if I were to open the servo and move the limit switch on the fully-extended side (desolder, drill, solder), would the servo have a correctly-functioning shortened range?

Hi Julien, if the stroke and thrust of the linear actuator is adequate for the task then it should be a fine option.

Hi George. Although either a linear servo or linear actuator could be made to do that, it would be more simple with a linear servo. An exact example would depend on how you want to go about controlling it. A no-programming option would be to use a servo recorder (part number SPC2000). Or you could use an Arduino and alternate between the servo.writeMicroseconds command and the delay command. Feel free to let us know should you have any additional questions tech@servocity.com.

@ServoCity 6 жыл бұрын

I'd double check whether the motor is in-fact an AC motor. Even though you plug your treadmill into AC power it's not a given that everything it runs runs on AC. There may be a power inverter built in which changes the AC input to a DC output. If you do find that it's AC, reversing polarity can be done by reversing the polarity of the starter winding.

Hi Angelique, we're happy to help answer your questions. The linear servos will run on any type of servo controller able to operate a hobby servo. The Actobotics Dual Servo Controller (www.servocity.com/actoboticsr-servo-controller-w-enclosure) was used to operate the linear servo in the video (reference 6:30). The battery was just a lawn mower battery so that the power source would be quickly recognizable by viewers. Any 12V source will be fine so long as it can provide enough current to operate your linear servo (more applicable when selecting the proper power supply that plugs into the wall). The capacity of the battery will depend on the desired run-time and the current draw from the linear servo will depend on the load and frequency of movement.

How do I make it automatically move in and out ? With some type of optical eye, like a sliding door, when someone is approaching it, and it opens for a min and closes automatically.

Hello Tim. Please check out our Apparition Apparatus project on Instructables (www.instructables.com/id/Aberration-Apparatus-Halloween-Prank/ ). It should at least get you pretty close. If instead of sending a PWM signal to a transistor to drive a motor, you sent a PWM signal to a linear servo you could do what you want. Feel free to reach out to our Tech Team at tech@servocity.com should you have any other questions.

Hi, nice video, question how can I make a automatic stop limits switch ?

@ServoCity 4 жыл бұрын

Hi, Harold. Many of the actuators have internal limit switches. The super duty actuators www.servocity.com/motors-actuators/linear-actuators/super-duty-linear-actuators have adjustable switches while the heavy duty actuators www.servocity.com/motors-actuators/linear-actuators/heavy-duty-linear-actuators have fixed limits. If you still have questions reach out to us at tech@servocity.com and we'd be glad to assist with your specific build.

Do you have any model that uses stepper motor instead?

I have a 2" actuator but only need about 1 1/2 of stroke. I want to run a non momentary switch but can I readjust the limit switch to stop on the out-stroke at 1 1/2? If so, how?

@ServoCity 7 жыл бұрын

Unfortunately, the limit switches are non-adjustable. Adding external limit switches would be the best solution for a shorter amount linear travel. Please let us know if you have any additional questions tech@servocity.com.

Will it work if we use a hi torque dc geared motor to drive a threaded rod using a timer belt and a pully enclosed in a hard PVC pipe/casing?

@ServoCity 6 жыл бұрын

Hi Parish, yes, that's one way to make a linear servo. Keep in mind that normal threaded rod is not meant for creating linear motion but for fastening. The threads of a lead screw are cut much smoother and more consistent to create linear motion while minimizing friction. Please let us know if you have any other questions tech@servocity.com. Thank you

Hi. I was considering to use a linear actuator to change the tilt angle of a structure holding solar panels. Overall, around 200kg. Would this option vaild to keep the structure to a certain angle for longer periods? Or the weight would push it back? Thanks

Hey @MrSavage77 did you find any linear actuator that worked for that kind of load?? I'm looking for something similar for a project.

I want to use these motors for my robotic arm project.But my doubt is whether these motors are able to hold the weight of robotic arm when not powered or are at halt at a certain point .

Hi Saksham, the HD series actuators are extremely difficult to backdrive. It depends on your setup, but I would highly doubt that it will cause the actuators to move when powered down. Let us know should you have any other questions tech@servocity.com.

That was an awesome demo guys..I have a question..I am trying to build a scale model of an excavator using the hydraulic principle with syringes.these motors act as Pistons so I should be able to use them instead right,I want to know what torque do these motors have cause I want my excavator to dig and lift just like the real thing.are they expensive to buy and could you pls do a demo on how to convert it to remote control..tnx guys

@ServoCity 7 жыл бұрын

You can certainly use linear actuators or linear servos in place of hydraulics if the speed, thrust, stroke length and overall size fit your model. Since we’re quantifying a linear force they are rated in pounds rather than a torque measurement. The amount of weight it can lift will depend on the placement of the actuator in your assembly. Prices vary based on what selection you make; we have HD linear servos which are the most plug-and-play solution for r/c. We offer HD linear actuators that are less expensive but more intensive to hook up to R/C (require a motor controller that can convert the PWM signal to a voltage that would get sent on to the motor). and SD linear actuators which are the same as the smaller ‘HD’ linear actuators but beefier for more industrial applications. The video covers how to connect a linear servo or linear actuator to a servo controller. An R/C transmitter and receiver is just a wireless servo controller so it’ll connect the same way.

Super!!!tnx for the prompt reply!! Another question..how does the boom of a crane extend..do they all have multistage cylinders or are they also equipped with linear actuators within each boom extension? And i.would really appreciate it if u could do a demo on how the excavotor rotates 360degs and still powers its tracks without its wirings and hydraulics getting twisted in the slew ring.i have looked online but not really satusfued with info or the lack of detail given. Cheers bros!!

Here’s a link to a brief explanation of how a crane boom extends: answers.yahoo.com/question/index?qid=20081125153736AAiN8mW. I would have to do more research on an excavator before commenting on the rotating base; sorry I couldn’t be more assistance in that department. Let us know if you have any other questions tech@servocity.com. Thank you

If your still around I would like to ask a question. I have an actuator that has stopped working (extending and retracting) and need to raise (retract) the shaft to its shortest length. What would be the simplest way to do this manually, if possible?

@ServoCity 5 жыл бұрын

It depends on the design of your actuator, but if you can access the lead screw driving the piston, just rotate the lead screw manually (assuming it will still turn) to manually extend/retract. Feel free to contact us should you have any other questions tech@servocity.com.

How do you call an actuator that has a linear motion , but also has the rotating motion (screw or turning head)

@littlegoobie 7 жыл бұрын

Is there an easy way to get this to go one way with a single wire that powers on, then reverse when power to that wire goes off? I was trying to think of a way to include a dpdt relay and i think that's the idea but i can't think of how to flip the polarity using that single wire's power change.

@greengeckodesign 7 жыл бұрын

Interestingly I made this ( circuits.io/circuits/2563498-dpdt-relay-to-toggle-polarity-via-on-off-switch ) recently to illustrate this very thing to someone. This of course would apply to the linear actuators not the linear servos. If you are using a microcomputer/microcontroller you will either want to find a DPDT relay which does not exceed the current rating of your pins (for example Arduinos are generally 40mA) or you could use a transistor to turn the DPDT relay on/off. Sort of like this ( www.instructables.com/id/Simple-Cheap-Motor-Controller/ ) only going to the relay instead of a motor and pulling it high/low instead of sending it a PWM signal.

@littlegoobie 7 жыл бұрын

I just checked out the circuits.io link with the relay. That will do exactly what i want. thanks. I just found the motor controller you're using too. I want one but i don't know if moving a light back and forth on the front of a truck is worth that much even though it would help me locate sasquatch.
