Reasons for unstable power of synchronous motors1. Poor circuit connection: The circuit connection of synchronous motors, such as poor circuit connection and poor contact of contacts, can lead to unstable motor power.2. Mechanical load changes: The operating environment and load changes of synchronous motors can affect the output power of the moto...
2024-11-2850101. Autotransformer starting method: The starting voltage of the motor is reduced through an autotransformer. During the starting process, the motor is first connected to the lower voltage side of the autotransformer, and then the voltage is gradually increased to gradually accelerate the motor. After the motor reaches its rated speed, connect it to...
2024-11-256300Common faults of synchronous motorsAlthough synchronous motors can maintain high work efficiency in most cases, there may still be some faults, as described below:1. Power reduction: Due to the inability of the rotor to rotate synchronously with the power supply, it may result in a decrease in the output power of the synchronous motor.2. Vibrati...
2024-07-256710Steps for calibrating permanent magnet synchronous motors:1. Determining the coordinates of the calibration starting point usually involves single component adjustment of the d-axis and q-axis components of the current, obtaining the gradient vectors of the d-axis and q-axis of torque variation with the current.2. Calculate the test current based ...
2024-07-055310Why is synchronous motor more efficient than asynchronous motor?
2024-06-055720Permanent magnet synchronous motors are AC motors that require AC power supply.The stator of a permanent magnet synchronous motor generates a rotating magnetic field through three-phase alternating current, thereby driving the motor to rotate.A square wave driven permanent magnet synchronous motor can also be considered as a type of brushless DC ...
2024-05-304610What are the structural differences between synchronous motors and asynchronous motors?
2024-05-205520The reason why permanent magnet synchronous motors have gradually become a research hotspot is mainly due to their various advantages and application prospects.Firstly, permanent magnet synchronous motors have the characteristics of high efficiency and high power factor. Compared to traditional electrically excited motors, permanent magnet synchr...
