Why does the single-phase motor not rotate?

Edward asks:
Single-phase motor does not rotate. How to determine what the malfunction is in the capacitor or in the motor?

The answer to the question:
Hello! And does it even buzz when turned on? If the problem is not buzzing, either in the wire or in the engine. In principle, it should start without capacitors, if you twist its shaft by hand. You can ring the motor windings - they should not be torn off and should not ring on the housing. The capacitor also ring, while the ring at the first moment of time can squeak, and then, as the capacitor charges, it stops squeaking. It may not squeak immediately if the continuity is weak or the capacitance is small.
