What is the reduction ratio of micro DC reduction motor? Simply put, it is the transmission ratio of the reduction gearbox, that is, the ratio generated when the micro DC motor is energized and outputs speed to the reduction gearbox instantaneously, represented by "i". For example, if the input speed of the micro motor is 1500r/min, and the output speed through the reduction box is 25r/min, then the reduction ratio is 60:1.
1. The importance of reduction ratio
Micro reduction motor is composed of a micro motor and a reduction box. The reduction ratio determines the output speed and torque of the motor. Some products require a motor with slow speed and large torque. At this time, the reduction ratio must be calculated to produce the micro reduction motor. Micro DC reduction motor that meets product requirements.
2. Classification of micro DC reduction motors
Since micromotors have many applications and are all customized, different products require different parameters. Therefore, there are many types and models of micro DC reduction motors, and different reduction motors are used in different fields. For example, planetary reduction motors, stepper reduction motors, worm gear reduction motors, etc. have different models, parameters, and reduction ratios.
3. Little knowledge about micro DC reduction motor
Under the same power, the faster the speed, the smaller the torque (force), and conversely, the lower the speed, the larger the torque. The larger the reduction ratio, the greater the torque and the lower the speed.
4. Calculation method of reduction ratio
1) Define calculation method
Reduction ratio = input speed/output speed
2) Gear train calculation method
Reduction ratio = number of driven gear teeth/number of driving gear teeth
3) Calculation method of reduction ratio of belt, chain and friction wheel
Reduction ratio = driven wheel diameter/driving wheel diameter
