Possible reasons:
(1) the power supply voltage is low;
(2) the original angle connection is connected to the star connection;

Treatment methods:
(1) increase the voltage;
(2) check the nameplate wiring method, correct the stator winding connection mode;
(3) after examination and symptomatic treatment.
