1, the starting torque is too small and the friction is too large, which makes it difficult to start.

2. If the motor is out of phase and single-phase, it is necessary to consider whether the main winding and auxiliary winding are short-circuited or whether the capacitor is damaged.

3. The motor related matching error is too large, which leads to uneven air gap and different stator and rotor axes.

It is recommended to find a professional to repair it.

Motor:

Motor refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. In the circuit, it is represented by the letter m (the old standard is d). Its main function is to generate driving torque as the power source of electrical appliances or various machinery. The generator is represented by the letter g in the circuit. Its main function is to convert electric energy into mechanical energy.
