Can realize the infinite speed adjustment Is accomplished by continuous change of frequency. Deceleration of the motor speed is through a adjustment of the motor. It can be at the same time to improve the output torque, torque output ratio according to the motor output by reduction ratio. Change the rotational torque, under the condition of the same power, the faster the speed of gear, shaft torque of the smaller, vice . separate the two meshing gears, achieve the goal of separate the motor and load., Weight: 0.34612575134 Pounds, Manufacturer: Ehwisbe
