The speed and stop direction of the decelerating stepper motor will only depend on the frequency and number of pulses of the pulse signal, but will not be affected by the change of load. Whenever the stepper driver receives a pulse signal, it drives the stepper motor to roll a fixed viewpoint in the set direction.
The so-called "step angle" rotation is that the angular displacement can be controlled step by step by step through the number of controlled pulses at a fixed point of view, and then the precise positioning can be achieved. Together, it can be used to control the speed and acceleration of motor rolling by controlling the pulse frequency, and then the rolling speed can be adjusted.
The difference between deceleration stepper motor and common stepper motor:
Reducer motor is composed of reducer (gear box) +motor, which can provide a considerable high speed speed, but the moment is very small, resulting in a considerable inertia of motion; the function of reducer is to control the down speed, improve the torque, and reduce the inertia of motion, which has reached the ideal speed and moment; for example, rare electric window cloth, electric winding gate, are all used. The speed reducer motor is adopted, which has slow speed and high torque.
Simply speaking, stepper motor is able to achieve fixed length and speed control. For example, when the worktable moves 1 meter, the speed of the motor can be set freely. There are rare application cases, such as 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 can rotate). However, the speed of the decelerating stepper motor is determined by the deceleration ratio, which can not adjust the speed of rolling; but the moment of the stepper motor is small, and the rolling 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 the deceleration motor can not do if it is three-phase asynchronous deceleration motor, it can come through the gearbox to decelerate, but the speed is not well adjusted, it is the need to speed through the frequency converter, but also can not do that is, I want to walk as many journeys as I want, want to achieve the stepper motor timing and speed work. If used (fixed length speed regulation) is to be combined with frequency converter and encoder.
Other deceleration motors have great motion force, and stepper motors generally do not produce much force. The stepper accelerator and decelerator can produce great motion force.
