Pre-excitation, zero-speed control, and servo lock

Pre-excitation is the process to control current while a motor is stopped so that motor torque can be generated immediately. There are two methods for this p... More Details >>

Can a single potentiometer operate two speed controller?

A single potentiometer cannot operate two speed controller. Reason: Since the control circuit and main circuit of the SC-A speed controller are not insulated... More Details >>
