What should I do if the motor heats up?

1. The air gap between the stator and rotor of the motor is very small, which is easy to cause collision between the stator and the rotor. In medium and small motors, the air gap is generally 0.2mm to 1.5mm. When the air gap is large, the excitation current is required to be large, thereby affect... Read More

Move your little hands and stay away from annoying motor failures?

Move your little hands and stay away from annoying motor failures? 1. The motor cannot be started 1. The motor does not turn and there is no sound. The reason is that there is a two-phase or three-phase open circuit in the motor power supply or winding. First check for supply voltage. If there is... Read More

Why are electric motors more likely to burn out now than in the past?

Why are electric motors more likely to burn out now than in the past? 1. Due to the continuous development of insulation technology, the design of the motor requires both increased output and reduced volume, so that the thermal capacity of the new motor is getting smaller and smaller, and the ove...

Eight kinds of motor coil failure reasons?

When the motor is in an abnormal working state (including electrical, mechanical and environmental aspects), the life of the motor coil will be seriously shortened. The reasons for the failure of the fan coil are: phase loss, short circuit, coil grounding, overload, rotor lock, voltage imbalance,... Read More
