For any motor, as long as the actual operating current of the motor does not exceed the rated current, the motor is relatively safe. When the current exceeds the rated current, the motor winding is at risk of being burned out. Among the faults of three-phase motors, phase deficiency is a relatively typical type of fault. However, with the emergence of motor operation protection devices, such problems have been better avoided.

Phase loss is a unique electrical fault of three-phase motors, which may occur during the testing stage of the motor or during its operation stage. It may be caused by problems in the manufacturing quality of the motor or issues during its use.

The standards for the number of motor starting times mainly depend on the type, design, and operating conditions of the electric motor. The common international and industry standards are as follows:

In today's era, energy issues are becoming increasingly prominent. With its unique advantages, permanent magnet synchronous motors are quietly leading a profound energy revolution. First of all, permanent magnet synchronous motors have the remarkable char...

With the introduction of the national "dual carbon" target requirements and policies, high-efficiency motors have quietly become a necessary supporting power source in the large-scale equipment renewal process. In addition to traditional markets such as new ...

In order to ensure that the rotor can rotate freely in the stator cavity during the operation of the motor, an air gap must be maintained between the rotor core and the stator core. Although there is no direct electromagnetic connection between the rotor and t...

The permanent magnet synchronous motor is mainly composed of a stator, a rotor and a housing. Like ordinary AC motors, the stator core is a laminated structure to reduce iron loss due to eddy current and hysteresis effects during motor operation; the winding i...

Overload is a practical problem that may occur during the application of motor products. Today we will give you a basic summary of this topic: Whether the motor is overloaded is relative to the motor's load capacity. When the load driven by the motor is grea...
