Why Did They Stop Making These? [Restoration]

This 1930s Leland Electric Co. throttle variable speed and direction electric motor is one of the coolest tools I have restored.
The restoration was fairly straight forward, but the mechanics of how this works were the most interesting. I give a quick explanation near the end of the video on how I believe this works, but if you specifically know, please leave a comment below.
The tag was in the worst condition I have ever seen, and I'd like to thank @joshsfick on Instagram for once again helping model the tag digitally so I could laser it out.
The wiring was also a larger than usual issue as there was a lot of deterioration.
I could see many use cases for this type of motor and I really wish they were still made like this today.
I'd like to thank @CRCAutoUS for sponsoring this video. I've switched to a food-grade penetrating oil from them as a more safe alternative, and it as worked just as well as the usual penetrating oils I've used.

There is a better tool for removing the rivet-heads from the name plate; use an old pair of wire cutters/dykes. Use a belt sander to flatten the side of the dykes where the edges meet up; this will allow the blades to slide under the rivet heads without significant marring of the nameplate

I've been doing motor repair professionally for over 35 years. That "string" is lacing that was doped in-place to keep the winding leads, attached to the commutator segments, from being pulled out of position by centrifugal force. The lacing should have been redone and "doped" (cemented with high temperature motor winding epoxy ). If this motor is used for any length of time it will have a catastrophic failure due to this major oversight. There is a special tool used for "under cutting" the space between the segments of the commutator. The tool removes a precise amount of the insulating bedding material the segments are embedded in and chamfers the leading and trailing edges of the segments to reduce wear, chatter and arcing of the carbon brushes, a very important step in turning a commutator. Minimally, these two items should be corrected before this motor is put in service.

@Ax89 2 ай бұрын

Good comment and explanation. I was wondering about the "string" removal.... It was originally there for a reason and removing and not replacing it without understanding it's function is not really a restoration.

@mikefochtman7164 2 ай бұрын

I'm sorry to say but this isn't a repulsion start induction motor, much rather a universal motor. This one lacks any mechanism that would disengage the brushes and short out the rotor windings once it reaches near synchronous speed, to which this doesn't seem to 'pull into'. It just seems to spin at an arbitrary speed controlled by the lever.

@TauCu 2 ай бұрын

@@LouAlvis It's hard to explain it without graphics of some kind but I'll give it a go. All this is effectively doing is biasing the position of the attractive/repulsive fields of the rotor in relation to the stator. Eventually the field generated by the rotor will match that of the stator at that position and the motor will not move. Continue moving the brushes and the field will move the rotor in the opposite direction. It doesn't matter if it's a brushed DC motor or a brushed AC/Universal motor this method works the same way.

@NeilWhelchel Ай бұрын

That is not what this is. This is an AC motor, and the brushes are not connected to power, they are connected to each other. (Shorted.) What is going on there is that depending on the position of the brushes, it is either including or excluding shunts (shorted turns) from the area of the rotor that is under the area of magnetic transition, so it is effectively a variable ratio.

These sort of motors are apparently called "repulsion motors" ( en.wikipedia.org/wiki/Repulsion_motor ). They seem to be very similar to a normal brushed AC motor (e.g. vacuum cleaner) but are wired up differently. My $0.02 for what it's worth. In a regular AC motor, mains current passes through one stator coil, through the rotor via the brushes, then out through the other stator coil. However, in a repulsion motor, mains is connected only to the stator coils. The brushes are shorted together. Depending on the angle of the brushes relative to the stator, that determines whether it runs fowards, backwards, or is stationary. It's now got me wondering if it would be possible to convert a regular AC motor into a repulsion motor with a bit of tinkering!

A lot of modern mains powered drills (at least from Bochs, DeWalt, Hilti and Metabo) have a brusholder that is turned to reverse rotation but the brushes are wired the same way as on models with a reverse switch. On some of them you can turn it partially and get lower speeds, but that's not the proper way since those have electronic speed controllers and some also 2 speed gearboxes, but I think all of them have an interlock to not allow the trigger to be pulled when the brush holder is in "neutral" or too close and the same way you can't reverse it while you have the trigger pulled

I've never seen an electric motor like that before, and I've spent most of my life around tools and equipment from the 10's to the fifties. Awesome! The speed control and reversing works on an electrical timing principle. Moving the handle, and thus the brushes, makes the magnetic interaction of the opposing fields happen sooner and increases the power / rpm. When you move the handle to the middle the opposing forces are directly over each other and nothing happens. Great video!!

This technology is still very useful and much more durable in industrial environments than solid state motor controllers. However please be advised: when the motor is going full speed and then is slammed into reverse the motor will create a voltage spike in the line. Any delicate electronic devices sharing the house wiring may be damaged. This principle is refered to as dynamic breaking. (when a running electric motor is disconnected and leads shorted to rapidly stop it). The motor momentarily becomes a generator until the inertia is lost. The leads can also be shorted with a high amperage resistor for less violent breaking. This brushed motor most likely can also run on DC. Great videos. Watching from far far away.

@merendell 2 ай бұрын

It could probably be converted to run on DC but it did not look like there was any electrical connection to the brushes. the AC in the stator is inducing a current in the rotor windings with the brushes completing the circuit. The alignment of the brush position adjusts the bias of the resulting magnetic field and by extension the speed and direction. The video's analogy of the water wheel is a good enough layman's explanation for what's happening magnetically. If the stator wiring is laid out how I suspect it is there would not be any significant adjustments needed there. Just connect DC voltage to generate a static magnetic field. The brush rigging however would need to be insulated and have its own power supply added to the brushes. You'd loose the speed variability with moving the lever however as you control the speed by adjusting the voltage. It would make setting neutral a lot easier but moving it around would just make your brushes spark while running. Honestly this thing is unique enough that I wouldnt even want to try. DC motors have their own design and theres no reason to try and cludge this interesting bit of old tech into being a DC motor that would be inherently temperamental unless you locked down the lever so it couldn't move.

Bent handle was probably an indication of the predominate direction the motor was used. Maybe high speed in one direction, (hard over) and slow speed in the other direction negating going hard over. Good stuff. We were taught shifting the field for speed and direction but never had our hands on it. Thanks.

Interesting motor; I've never seen, nor heard of such a thing, and I have friends that have come across a lot of unique equipment. I have been able to weld cast iron with a wire feed welder, and it's held up perfectly. I first discovered it would work, after my dad tipped over our Harbor Freight drill press, and broke the platform crank in two. I made the obligatory double-groove grind for the braze, and thought I'd try out my new wire feed welder, with ER70-S7 wire, just to tack the edges together. It went really nice, so I thought I'd make a base pass. That went so well, that I welded it completely, and it never broke again, even after scrapping it some 30 years later. That went so well, that I welded a huge crack in my neighbor's 390 Ford exhaust manifolds. He held the rosebud down there to keep it cherry red, and I made pass after pass, filling in the gap. He drove it for several years, and they still weren't leaking 15+ years later, when he sold the truck. I found cast iron welds at a much lower temperature.

@dmclegg66 2 ай бұрын

The key to welding cast iron is preheating and post heating don't let it cool fast after welding keep heating it and slowly let it cool that keeps it from cracking.

@berryj.greene7090 Ай бұрын

Very interesting! I've never seen this precise device before. The commutator is just a switch that applies current to successive windings as it rotates. The electromagnetic forces make it turn. However with the extra brushes you can produce two fields that will balance each other at the central position. In theory it will then be drawing a minimal current due only to eddy currents and any losses. It's a very interesting concept. I think that string should have been replaced and lacquered down with a shellac of some kind as it supports the wire ends of the armature (rotor?) coils. Good job and instructional video. I wonder what it was used for?

Im studying to be an electrician, we have one of these ate school. They went the way of the dodo when cheap inverters/speed controllers became available, because they have a massive flaw many other motors share; it has brushes, and brushed motors require maintenance much more often than induction motors. Asynchronous motors on the other hand only need yearly lubrication of their bearings for the most part.

@guillaumepare9651 2 ай бұрын

What maintenance? Decades ago, I had a Dremel prcision tool. From times to times I had to check the brushes. Two 5 cents caps, then the spings and brushes at the tips of them. Changing brushes that were about to fail or were gone were like a 5 min operation at most. Brushed engines have cons but they also have pros.

No mechanic or anything other than a wise old fart but Just take a good look at anything made in the past 30/40 years and is it still working and/or repairable? Most of 'todays' goods are made for 'the throwaway society' Yet 60+ years ago they built machines to last - yes they had to be maintained / serviced but they lasted and repairing them was easy. 40 years ago my dad got 3 non running twintubs (washing machine) from an auction - from those 3 he made one functional....for my first home. Now...I'm looking for a pre '86 car [pre engine management/pre computer/pre electronics because they're easy to maintain and hardly anything goes wrong except body rot and crashes....nowadays a simple rear end shunt will write a vehicle off.

@donwillman4587 2 ай бұрын

To put it simply, the electromagnet created in the windings is interacting with the fixed magnets in the casing. As you move the location of the brushes, you're changing the direction and efficiency of push. As you move further away from center, the motor gets more and more efficient- ie: more speed. The energy is still going through the armature in other positions but- instead of creating torque, it's creating heat- which it likely why they're not made anymore. Too many barn fires.
