The output speed of the reducer is smaller than the theoretical value.

If it is rated load, the output speed of the reducer is smaller than the theoretical value.

1. If the reducer is separate, the speed ratio of the reducer is the transmission multiple of the internal gear of the reducer. For example, in a gear reducer, the product of the number of teeth of all large gears divided by the number of teeth of all pinions is the speed ratio.

2. If the motor and the decelerator are integrated, such as the miniature deceleration motor, the output of the motor is toothed and meshes with the gears on the decelerator, then the deceleration ratio is: the product of the number of teeth of all driven gears divided by the number of teeth of all active gears is the speed ratio.

3. Drive Ratio Motor Input Speed Divided by Retarder Output Speed = Drive Ratio

The DC Gear motor , consisting of a DC electric motor and a gearbox, is at the heart of several electrical and electronic applications. ZHAOWEI have been designing and developing such high quality mini DC gear motors in an easy-to-mount package for a range of products and equipment. Our miniature gear motor work smoothly and efficiently, supporting these electrical and electronic applications. These geared motors have reduction gear trains capable of providing high torque at relatively low shaft speed or revolutions per minute (RPM).  ZHAOWEI DC geared motors reduce the complexity and cost of designing and constructing applications such as industrial equipment, actuators, medical tools, and robotics. ZHAOWEI has engineered a range of planetary and spur gear motors (also known as mini-geared motors and micro-geared motors) suitable for many future and existing applications. The main characteristics of these gear motors are miniature form factors, offering significant strength
