• Why does the variable frequency motor run with shaft current

    Shaft current occurs when a variable frequency motor is running, and it is common in high-power variable-frequency motors. Because when a high-power variable-frequency motor is running, when the stator core of the motor is unbalanced in the reluctanc...

  • Talking about the thermal stress in the starting process of high-power motors

    For high-power motors that require forward and reverse rotation, if the full-speed motor is braked in the reverse direction and rotates in the reverse direction, the energy consumed by the rotor at this time is much larger than the energy consumed du...

  • What are the requirements for a high-quality three-phase asynchronous motor

    There are many three-phase asynchronous motor manufacturers, and the quality and value of each are not communicated. Although my country has already drawn up the standards for motor production design skills, many companies have conducted adjustments ...

  • The difference between frequency regulation motor and ordinary motor

    Compared with ordinary motors, there is not much difference in appearance between frequency conversion motors and ordinary motors, but there is a big difference between the two in terms of function and utilization. The frequency conversion motor is p...

  • Explanation of main noise sources of motors

    The noise source of the motor can be divided into electromagnetic noise, machine noise and ventilation noise according to the cause of occurrence. Electromagnetic noise The magnetic field in the air gap of the motor is contaminated with each other an...

  • What is the cause of motor vibration

    The vibration of the motor will shorten the winding insulation and bearing life, affect the normal lubrication of the sliding bearing, and the vibration force will promote the expansion of the insulation gap, which will cause the intrusion of externa...

  • What customers should pay attention to when purchasing high-power motors

    Customers should pay more attention to these points when purchasing high-power motors: materials, manufacturer qualifications, quality systems, etc...factors, not just value! Because these factors are the key factors that affect the quality and life ...

  • Can ordinary three-phase asynchronous electric performance be used as a variable frequency speed moto

    With the growth of modern household products, variable-frequency speed-regulating motors have become the preferred power equipment for industry equipment such as fans and pumps. Some customers ask Wanbang Motor: Can ordinary three-phase asynchronous ...
