 Forced start of three-phase motors

The soft starter serves as a start-up aid for 3-phase induction motors. Based on the principle of Phase Control, which is a method for power limiting, applied to AC voltage, also known as “Phase-fired control” or “Phase Cutting”, the power of 3-phase induction motors can be reduced to obtain a soft start or also a soft stop.

0:24 Why using start-up aid?

1:28 Function of a Soft Starter

3:27 Torque decreases during starting

3:51 2-phase or 3-phase Soft Starter

5:08 Soft Starter compared with VFD and Star-Delta-start-up

Learn from the basics how an electric motor works, where they are used, why they are used, the main parts, the electrical wiring connections, induction motor, alternating current AC, electrical machines, rotating magnetic field, star delta, wye delta.

The Three-Phase Induction motor is probably the most commonly used electric motor in industry. The problem with this motor is the high starting current, which is 7 to 10 times the rated current. Especially large Three-Phase Induction motors should be started with the appropriate starting aid.
