Brushless Inrunner vs Outrunner Motor

Brushless Inrunner vs Outrunner Motor - RC Motor Basics

In this video, we look at key performance differences between the Brushless Outrunner motor and the brushless inrunner motor.
When comparing the inrunner vs the outrunner, the outrunner having a larger diameter allows it to generate more torque at the cost of Kv or RPM per volt. The inrunner brushless motor spins more RPM with less torque.
It's important to understand the differences between the motors in order to select the best motor type for your application.

Sounds correct that larger diameters with larger torque has smaller RPM KV value.

Wow, That is nice piece of knowledge. Thank you for this video. As you are very familiar with motors maybe you could kindly help me. I was wondering if is it possible to push the shaft in the inrunner motor to make it double sided shaft motor? When I look at the rotor shaft, it seem solid and glued/soldered to the magnets. I am at the start of my new rc car project and my "jerky mind" thought about mid engined, double shaft, center driven layout. Without the pinion/spur design. I have found some 700-800 kv motors for this project but the main showstopper is this "double shafted motor" thing. Cheers and Happy New Year :)

Some outrunner motors allow you to move the shaft and even swap its orientation. This is done by removing set screws. I'm not sure the shaft would be long enough however but you could replace it with another. Happy New Year

Thanks for support :) However those holding screws seems to be present only in outrunner motors (my small experience) In the inrunners that I had there are only some sealing that seems to he glued. Rotor+shaft+magents look like bounded forever :) Maybe hydraulic press or other tomato squisher could be useful?

@RCexplained 3 жыл бұрын

That's right. I have a few outrunner where the shaft can come out. I have never tried to get the shaft out of an inrunner. Maybe if you are able to cool the shaft it can help as cold Temps will shrink the metal. Not really sure.

very valuable info. tks a lot for pylon f5d racing in summer do u think inrunner could have more advantages in general? re the weight to thurst ratio and the close cabinet of the pylon inrunner still the best choice ? tks

@RCexplained 3 жыл бұрын

yes my vote inrunner

How to know that my motor is a brushed DC motor or a inrunner BLDC motor ?

@RCexplained 5 жыл бұрын

A brushless motor uses 3 wires where as a brushed motor uses 2. This would be the easiest way to determine the difference in a radio controlled application.

@hafizuddinmohdlowhim8426 4 жыл бұрын

I want to build high pressure water pump. I choose inrunner BLDC because the pump needs high RPM and I can cool the motor easily. Is my decision right?

@RCexplained 4 жыл бұрын

What is high RPM ?

@hafizuddinmohdlowhim8426 4 жыл бұрын

RCexplained RPM: 160000rpm. Power: 4MW

@RCexplained 4 жыл бұрын

@@hafizuddinmohdlowhim8426 that's a lot of RPM. I don't know of a motor that can spin over 100,000 RPM. Most outrunners max out at about 30,000.
