• The connection between common asynchronous motor and frequency converter

    The influence of variable frequency speed regulation on motor and its efficiency: no matter what kind of control method is adopted, the voltage pulse output to the motor terminal is non sinusoidal. Therefore, the analysis of the operation characteris...

  • Guide for quick installation and use of reducer

    Reducer is a common power transmission mechanism, which is used in various mechanical transmission systems. The installation and use of the reducer must comply with the technical specifications and standards, which is directly related to the operatio...

  • Correct selection, installation and maintenance of precision planetary gear reducer

    Precision planetary gear reducer is widely used in the drive system of servo, stepper, DC brushless control motor (also known as drive motor) because of its small size (basically the same diameter as the matching motor), high transmission efficiency ...

  • Heating power analysis and cooling mode selection of reducer

    During the normal operation of the reducer, due to the loss of efficiency, part of the input power will be converted into heat energy, which makes the internal temperature of the reducer rise. If the temperature is too high, the internal parts will b...

  • The relative influence of the frequency converter's harmonics on the motor and its bearings

    Frequency converter adjusts the voltage and frequency of the output power supply by the internal IGBT switch, and provides the required power voltage according to the actual needs of the motor, so as to save energy and speed. Influence of Frequency C...
