    • This torque value is the rated output value of the reducer, not the final motor + output torque value T after reducer.
    • The formula for calculating the output torque after the final motor + reducer: T = rated torque of the motor * reduction ratio * 0.6, and T≤ rated allowable output torque value of the reducer.

    300 W DC Worm Gear Motor Speed Torque Curve

    • 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.

    Tips: Difference between a DC worm gear motor and a gear motor?

    Worm gear motor and gear motor are two widely used reduction equipment. Worm gear motor is a kind of power transmission mechanism that uses gear speed converter to decelerate the number of revolutions of the motor to the required number of revolutions and obtain a larger torque. In the mechanism used to transmit power and motion, the application range of the reducer is quite wide.

    The basic structure of the worm gear motor is mainly composed of the driving parts worm gear, shaft, bearing, box and its accessories. It can be divided into three basic structural parts: box body, worm gear, bearing and shaft combination. The box body is the base of all the accessories in the worm gear motor. It is an important accessory that supports the fixed shaft system components, the correct relative position of the drive accessories, and supports the load acting on the reducer. The main function of the worm gear motor is to transmit the motion and power between the two interleaved shafts, and the main function of the bearing and the shaft is to transmit power, operate and improve efficiency.

    Gear motor is generally used for low-speed and high-torque driving equipment. The ordinary reducer of the motor will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the drive ratio.

    Gear motor is a drive device enclosed in a rigid box. It consists of several gear drive groups, shafts, bearings, output shafts and other parts. It can be used to change the speed and torque between the input shaft and the output shaft. The gear motor uses all levels of gear drive to achieve the purpose of speed reduction. The reducer is composed of various levels of gear pairs. For example, a small gear can be used to drive a large gear to achieve a certain reduction purpose, and then a multi-stage structure is adopted, which can greatly reduce the speed.

    Existing reviews of 300 W DC Worm Gear Motor, 12V/24V/48V
    Great quality.
    I like this worm DC gear motor. Runs exactly at the speed specified, lots of torque, strong shaft and gears, decently high torque and perfect for the robotic arm I’m building. Easy to use and control. I would recommends this product in a heartbeat.
