Overview:
The working principle of the permanent magnet synchronous motor is the same as that of the electric excitation synchronous motor, but the magnetic flux provided by the permanent magnet replaces the excitation winding excitation of the latter, which makes the structure of the motor simpler.In recent years, the performance of permanent magnet materials has improved and...

Overview:
A permanent magnet synchronous motor is a synchronous motor that generates a synchronous rotating magnetic field by exciting permanent magnets.Permanent magnets are used as a rotor to generate a rotating magnetic field.The three-phase stator winding reacts through the armature under the action of the rotating magnetic field and induces a three-phase symmetrical current.this...

Overview:
In order to avoid and reduce the occurrence of accidents of sudden damage to the three-phase asynchronous motor, the three-phase asynchronous motor needs to be regularly maintained and overhauled. If the motor is overheated and the stator winding insulation is too low during use, it needs to be stopped for maintenance immediately.Three-phase asynchronous motor...

Overview:
The temperature rise of the motor refers to the difference between the temperature of the windings and the temperature in the cold state when the motor is running at the rated load to a stable state. The higher the temperature rise, the worse the performance of the motor. Below I will give the reasons for the increase in the temperature of the motor. The factors are as follows: 1. Copper consumption...

Overview:
The difference between ordinary asynchronous motors and variable frequency motors: ordinary asynchronous motors are designed according to constant frequency and constant voltage, and it is impossible to fully adapt to the requirements of variable frequency speed regulation.The following is the influence of the frequency converter on the motor: 1. The efficiency and temperature rise of the motor, no matter what kind of form...

Overview:
In a society with energy shortages, high-efficiency and energy-saving motors are widely used, so what is the difference between high-efficiency and energy-saving motors and ordinary motors? (1) The output power of ordinary motors is less than energy-saving motors.The output power of ordinary motors is only 50% of the input power, while energy-saving motors can reach...

Overview:
After a long-term operation of the motor, various failures will occur. To determine the cause of the failure in time and deal with it accordingly is an important task to prevent the expansion of the failure and ensure the normal operation of the equipment.When the motor is running, pay attention to observe whether the motor smokes, vibrates, or is too large...
