Synchronous starter
Before we start synchronous motor starting methods, let us brush up on some basics of synchronous motor. 1. A Synchronous motor belongs to the category of AC motors. But, a single supply source is not enough to start it. It requires a double excitation systemto operate the motor. 2. The stator of this motor … See more The main problem that prevents the motor from starting is the rotor inertia. If we can break this resting inertia, we can obtain a continuous (unidirectional) rotor torque. For this, we have different synchronous motor starting … See more The most common synchronous motorstarting methods are: 1. Supply frequency control 2. Using an external motor 3. Small pony motors 4.
