Reduction motor is composed of reducer (gear box) and motor. The motor can provide a considerable high speed speed, but the moment is very small and the inertia of motion is quite large.
The function of the reducer is to control the descending speed, improve the torque, and the inertia of the descending motion. It has reached the ideal speed and moment. For example, the rare electric window cloth and the electric rolling gate all adopt the decelerating motor, which has the characteristics of slow speed and large moment.
Simply speaking, stepper motor is able to achieve constant length and speed control. For example, when the worktable moves 1 meter, the speed of the motor can be set freely. Rare use cases are, for example, stepper motor on the worktable of milling machine.
The difference between the two is that the stepper motor can achieve constant speed and punctuality (how long you want to walk and how fast you rotate can be set). However, the speed of the decelerating stepper motor is determined by the deceleration ratio, which can not adjust the speed of rotation; but the moment of the stepper motor is small, and the moment of the decelerating motor is large.
Stepper motor, can be fixed length and speed control, for example, the workbench walking 1 meter, speed 500R/MIN, but deceleration motor can not do if it is three-phase asynchronous deceleration motor, it can achieve deceleration through the gearbox, but the speed is not adjustable, it needs to go through the frequency converter speed control, and it is impossible to say how many journeys I want to go, want to achieve stepper motor timing and speed work. If used (fixed length speed regulation) is to be combined with frequency converter and encoder.
In addition, the motion force of the deceleration motor is large, the force of the stepping motor is not very large, and the motion force of the stepping accelerator and decelerator is large.
