The main advantage of an electrical drive is that the motion control can be easily optimized. Put simply, the system which controls the motion of electrical machines are known as electrical drives.A typical drive system is assembled with an electric motor (there may be several) and a sophisticated control system that controls the rotation of the motor shaft.

In some rare cases where a strange motor configuration or a motor with 6 or more poles is used, the motor inductance may be too low and a reactor may be needed. Running multiple motors on one drive may also result in a low inductance load and the requirement of an output reactor. Reactors at the drive output to reduce the effect of reflected wave:
