High Torque DC Motors
The best way to obtain high torque from a simple 12v DC motor probably is using some kind of speed reducer attached to the motor. It will "swap" velocity for torque.- Odair

Reversing a three phase electric motor.
A 3-phase motor doesn’t need to be stopped before reversing (of course it’s desirable, but not necessary). The magnetic field is able to stop the rotor and start the reversing procedure. Some cares must be taken. Certainly it demands an extra current drawing, that is not higher than the peak...- Odair
