Questions for repetition and control
1. How does a single-phase induction motor generate its rotating field?
2. Explain the operation of a three-phase asynchronous motor through a single-phase mains.
3. Explain the efficiency principles of the universal motor torque.
4. What must be heeded if a motor which had been connected to the alternating voltage mains, is to be driven by direct current?
