These Motors Can’t Be That Difficult: Required Power.
Many years ago, during the industrial revolution, factories, meal mills and woollen mills Etc. were powered by a simple device known as a water wheel. A very simple, but efficient device indeed.
A big heavy wheel on an axle which was driven round and round by a single bucket attached to the wheel which filled with water from a higher source letting gravity do the turning. As it turned another bucket was filled, the first one emptied underneath, and so the turning was continuous.
An electric motor is exactly the same, but requires too much expensive power to turn it, because of the too small radius of the power points. The buckets if you like.
A bigger wheel. Fill all the buckets at precisely the same time even, empty and fill again all in a split second, and the power is going to be much greater. As the power used, maybe from a dynamo, Magneto device, is different from the power taken off by an alternator to power the start and the lights on a vehicle, there can’t be much problem. Computers today can do all the synchronizing if required. It is not rocket science. I still think they should turn in one direction only. A gear box doing the reversing Etc.
Electric motors were designed when power was thought to be infinite, and the internal combustion engine ran on a plentiful supply of cheap gas. (Fuel) They were only designed for the purposes they are used. They need to be re-thought to do more now.
Of course they might need to be renamed. How about ‘electric (as in water) wheels?’ Oh, maybe not.
