The magnetic steel of the permanent magnet motor is on the stator or the rotor？
Most of the motors are internal rotors, that is, the motor rotor is located inside the stator and outputs mechanical energy through the rotating shaft. The external rotor motor is on the contrary, the initial wire winding is placed on the iron core fixed together with the shaft, the motor is in a...Read More -
Motor bearing and grease selection
The motor is widely used, due to the power size, installation type, protection grade, load type and connection method is different, the selection of bearings is also very different, only the correct selection of bearing type, so that it can adapt to the operating requirements of the equipment, in...Read More -

Why should we choose deep groove rotor for squirrel cage asynchronous motor?
With the popularization of variable frequency power supply, the starting problem of motors has become easy to solve, but for ordinary power supplies, the starting of squirrel cage rotor asynchronous motors has always been a problem. From the analysis of the starting and running performance of as...Read More -
Large motor shaft voltage analysis and solutions
Four sets of bearings were replaced consecutively at the shaft extension end of a motor, which was eventually found to be due to shaft voltage. Shaft voltage is a frequent problem in the operation and testing of high-voltage and low-voltage high-power motors. In order to ensure the normal operati...Read More -
When selecting an inverter, is it necessary to consider the slot characteristics of the motor rotor?
For continuous changes in speed requirements for the conditions, will use a frequency converter to drag the motor, that is, through the motor power supply frequency changes, to achieve stepless adjustment of motor speed. In the original tweet we have talked about, through the frequency converter ...Read More -
