    Tips: Difference between gear motor and VFD
    The VFD changes the routine power supply into AC power supply of various frequencies, so as to realize the variable speed operation of the motor. In this process, the control circuit completes the control of the main circuit, the rectification circuit transforms the AC into DC, the DC intermediate circuit carries out smoothing filtering to the output of the rectification circuit, the inverter circuit transforms the DC into AC. As for the VFD that requires large amount of calculation, such as the vector controlled inverter, a CPU for torque calculation and some corresponding circuits may also be required. Frequency control is realized by changing the frequency of power supply for motor stator winding.

    Gear motor is a power transmission mechanism that can be used for both high torque and common speed applications such as conveyer belt, mixer, windlass, clapper and automation special machine etc.. Moreover, with the development of industry and the automation of factories, demand for gear motor keeps on increasing. There are many ways to decelerate, but the most commonly used method is to decelerate with gears as it can reduce the space and costs.

    • Instantaneous maximum torque line
      The maximum torque momentarily impacts the load when the motor is started.
      Beyond this torque, the over-current protection of the driver will cause the motor to stop.
    • Short time operation area
      The motor can run at a short time within this torque range at different speeds.
      If the operation time is too long, the motor will generate heat, which may cause the motor to stop or burn.
    • Rated operating torque line
      The rated torque of motor running at different speeds, and the motor can run for a long time at this torque.
    • Continuous operating area
      When the motor rotates at different speeds, it runs continuously in this corresponding zone.
