ELECTRIC MOTOR DRIVES

3.2
An electric motor drive system is made up of five main components. Figure 3.1 shows a block diagram of an electric motor drive. The input to the drive is the power source. The power source is the energy for the system. Next is the power electronic converter. The electronic converter manipulates the voltage, current, and frequency provided by the power source. To control the system, a controller is needed. Of course, the remaining two components of the system are a motor and a mechanical load.
In the following sections, different types of electric motor drive systems are explored. Drives for DC and AC motors are explained in detail.
