I'm afraid I can't be as much help when discussing internal combustion engines. But let's look at it mathematically for a moment. At low engine RPM, the torque is low -- there is a whole torque curve, low at both the low and the high end. Power is the product of the angular velocity and...

Oh, a point about the motor controller and voltage multiplier circuitry. This is typically done at a rate ranging from around 100 hz to maybe 50 khz, depending on the application. Fast enough that, to the motor, it is seeing essentially a continuous load or source of current or voltage. This...

OK, here's how regenerative braking works. First, a little background information about motors and generators. This is all directly derived from the basic electromagnetic physics of a conductor in a magnetic field. Basically, a motor and a generator are the same thing, used differently. Every...
