In the alternating current motor class, we have the three-phase asynchronous and synchronous motor classification.
We must not forget that the single and two phase motors are also alternating current motor.
ASYNCHRONOUS SINGLE-PHASE MOTOR WITH NORMAL START-UP TORQUE
The single-phase motors have been designed for a single nominal voltage.
They have two windings (start-up and operation) that must be connected to the capacitor when the motor is installed. The rotation direction can be reversed by inverting the power supply of the operating winding or the start-up of the single-phase motor.
Used to control the speed of three-phase motors in general industrial applications
The purpose of the regulator is to maintain the output voltage “ov” in a predetermined value over the expected current load range, regardless of the variations in the load’s current, input voltage to the “vi” regulator and temperature “t”.
