• ## What is the working principle of gear reducer?

Gear reducer uses gear transmission at all levels to achieve the purpose of speed reduction. The reducer is composed of gear pairs at all levels. For example, using small gears to drive big gears can achieve a certain purpose of speed reduction, and ...

• ## What is the deceleration ratio? How to calculate the reduction ratio of the reduction motor?

The reduction ratio is output speed by engagement of large and small gears, and multi-stage gear engagement, with lower reduction ratio and greater torque. The reduction ratio is generally understood. For example, the reduction ratio of 1:100 is the ...

• ## What do you mean by a class 4 motor?

Level 4 motor refers to the motor with 4 stator magnetic poles. The actual synchronous speed of 1430r / min is 1500 rpm motor. According to the speed formula: speed = time (60s) × frequency (50Hz) divided by the number of poles, one pole pair is two ...
