Question:

Why should the motor slow down?

Why does the motor slow down? I'm not in engineering do not understand, a lot of the motor and the turbine box collocation to decelerate, is gear box and gear motor or some others do not need to slow down reduction hope expert advice, speak understand the theory of strength. Thank you!Is not all motors should be equipped with a reducer, in which case should the motor be equipped with reducer?

Answer:

A child learning to walk will start to slow down so you'll have to exercise his muscles to control speedThe motor is also a machine, there is a need to vigorously torque low speed, so you have to use the reducer, the car can not start on the 1 speed, but also to slow down
After rational design, the volume and cost of the motor reducer are less than that of the direct drive motor after the two are added togetherBut the disadvantage is easy to wear, drive back difference, accuracy is not high, only suitable for output, not suitable for high-precision position control.
In order to output a certain power, to reduce the cost of saving materials, the volume of the motor is as small as possible, according to the 2), the corresponding torque is small, according to 1), then the speed of the motor is designed to be high, affected by the bearing cost, speed is not too high.The actual operation of the use of less than the high speed, but the need for greater torque, so the needs of the reducer, reducer role: small torque * high speed = big torque * low speed
1) energy conservation, that is, the power output of the motor = torque * speed2) the volume of a general motor is proportional to the torque3) the maximum speed is limited by the linear speed of the bearing, and the higher the speed of the bearing, the more expensive the bearing
