錦州Motor housing

Detailed

In some cases, the motor shell will produce mechanical resonance in a certain frequency band when the motor is running. At this time, the frequency hopping setting method of the frequency converter can be used. Generally, the frequency converter has a "frequency hopping" setting, which is used to set the frequency of motor resonance. When the frequency converter operates in this frequency band, it skips this frequency to avoid motor resonance. The carrier frequency can be set higher appropriately, but it will bring some problems. If the carrier frequency is set too high, it will cause interference to other equipment, especially when PLC communication mode is adopted. Therefore, the carrier frequency should be set according to the actual situation on site. In cold stamping production, in order to meet the needs of different stamping work, it is necessary to use various types of presses. There are many types of presses, which can be divided into mechanical presses and hydraulic presses according to different transmission modes. Mechanical press is widely used in cold stamping.
