The causes and treatment of the fault that the motor is difficult to start or cannot start are as follows:
(1) A fuse of a phase is broken, the phase is missing, and there is a click. If the two-phase fuse is broken, the motor does not move and is silent. Find out the cause of the fuse blow and replace it with a new one.

(2) The power supply voltage is too low, or the buck is reduced when starting up. The former should find the reason; the latter should increase the starting pressure drop appropriately. If an auto-decompression starter is used, the tap can be changed to increase the starting voltage.

(3) The stator winding or the rotor winding is broken. It may also be that the wound rotor brush has no contact with the slip ring and should be inspected and repaired.

(4) The stator windings are short-circuited or grounded, and can be inspected by a megohmmeter.

(5) The stator winding wiring is wrong. If the triangle is connected to a star by mistake, or the first end is reversed, it should be checked and corrected.

(6) The stator rubs against the rotor core.

(7) If the bearing is damaged or stuck, the bearing should be replaced.

(8) If the load is too heavy, the load should be reduced.

(9) Mechanical failure, the belt-operated machine itself is not flexible, or it cannot be rotated.

(10) The belt is pulled too tight and the friction is intensified. The tightness of the belt should be adjusted.

(11) There is an error or fault in the wiring of the starting equipment, check and correct, and eliminate the fault.
