How To Select The Planetary Reduction Micro DC Motor?

Planetary reducer motor is a new type of reducer with wide versatility. The motor is mainly composed of planetary tank, solar wheel, planetary wheel, inner gear ring and other components. The planetary tank is composed of multiple planetary wheels and solar wheels, the planetary wheel and solar wheel are connected by the key, and the deceleration output shaft through the inner gear ring. In the process of motor work, the parts inside the motor will be coordinated movement, so as to realize the deceleration effect of mechanical transmission.

1. When selecting a planetary reducer, please multiply the rated torque of the servo motor by the deceleration ratio, and determine the required output torque and speed. Before selecting the motor reduction ratio, it is necessary to specify the required output torque and speed torque. Different types of applications have different requirements for the motor output. For example, some applications require high speed but lower output torque, while others require high output torque but lower speed. To understand the characteristics of the motor, in the selection of deceleration ratio, but also need to understand the characteristics of the motor, such as operating voltage, rated current and input power. These parameters help you determine whether the required output requirements. Considering mechanical load, mechanical load is the resistance provided from the motor output shaft to the load (e. g., gear, belt, or chain). When choosing the deceleration ratio, the influence of mechanical load on the deceleration ratio. The larger the mechanical load, the greater the deceleration ratio that needs to be selected in order to provide sufficient output torque. Choose the appropriate deceleration ratio, according to the above factors, choose the appropriate deceleration ratio is very important. Typically, choosing a higher deceleration ratio provides a greater output torque, but reduces the output speed of the motor. Instead, choosing a lower deceleration ratio increases the output speed of the motor, but the output torque decreases. The required output torque and rotational speed are therefore counterbalanced to choose the most appropriate deceleration ratio.

2. Consider the return trip gap. The return trip gap has a direct relationship with the load of the transmission system. The working occasions with large load and harsh working environment require small return clearance to ensure the tightness of transmission system, and large return clearance can be appropriately selected in small load and light working environment to relieve the wear of transmission system. Transmission accuracy: the return clearance and the transmission accuracy are also closely related. Usually, the transmission accuracy is high, the return clearance should be small, otherwise it will affect the transmission accuracy. In the transmission accuracy requirement is not high, the appropriate large return clearance can be selected to reduce the cost and production difficulty. Finally, you should also consider the weight of the fitted motor. A speed reducer is only allowed to be matched with a motor of less than a certain weight. The motor is too heavy, and the long-time operation will damage the input flange of the speed reducer.

Selection considerations:

The selection of planetary reducer motor should follow the principle of combining applicability and economy, that is to say, the technical indicators can not only meet the requirements of the equipment but also save the cost. The structure type, bearing capacity, deceleration ratio, output speed, axial force, radial force, backgap and other internal performance indicators should be considered. Consider the external factors such as the installation form, working conditions and working environment.
