Summary:...
In order to realize the high-performance operation of the stepper motor, it is important to know whether it is necessary to equip the stepper motor with a
planetary gearbox.
The role of planetary gearboxes is closely related to the development of motors. With the introduction of motors with speed control functions, the main function of the planetary gearbox is to amplify torque. However, with the widespread acceptance of stepper motors, in order to meet the speed and position control requirements, planetary gearboxes have found new uses, including increasing torque, improving allowable inertia, and reducing motor vibration. In addition, the precise positioning ability of the motor puts forward requirements for high-precision and non-backlash planetary gearboxes.
The design focus of the planetary gear reducer used in the stepper motor is the allowable high torque, long life, low noise, wide gear ratio range, and can be used as a power source continuously. Stepper motors and other control motors are designed to achieve precise positioning, so these gearboxes for motors must provide the same level of accuracy.
In addition to the correct torque, speed and inertia values of the gear motor, it is also important to choose a high-precision, low-recoil planetary gear reducer, especially when connecting the gear box to the stepper motor.
