WebbYou can run DC motors in both directions. Some DC motors will run with better performance in one direction than the other, due to commutator advancement built into the motor when it was designed. Motors from Precision Microdrives are generally wound ‘neutral’, that means with no commutator advancement. This, in turn, means that mostly …
A DC motor is any of a class of rotary electrical motors that converts direct current (DC) electrical energy into mechanical energy. The most common types rely on the forces produced by induced magnetic fields due to flowing current in the coil. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current …
