Stepper motor acceleration and deceleration process control technology
Because of the wide application of stepping motors, there are more and more researches on the control of stepping motors. If the stepping pulse changes too fast when starting or accelerating, the rotor cannot follow the change of the electrical signal due to inertia, resulting in a blockage. Rotation or out of step may produce overstepping due to the same reason when stopping or decelerating. In order to prevent stalling, out of step and overstepping, and increase the working frequency, it is necessary to control the speed up and down of the stepping motor.
The speed of a stepper motor depends on the pulse frequency, the number of rotor teeth and the number of beats. Its angular velocity is proportional to the pulse frequency and synchronized with the pulse in time. Therefore, when the number of rotor teeth and the number of running beats are fixed, the required speed can be obtained as long as the pulse frequency is controlled. Since the stepper motor is started by its synchronous torque, in order not to lose the step, the starting frequency is not high. Especially with the increase of power, the diameter of the rotor increases, the inertia increases, and the starting frequency and the highest operating frequency may differ by as much as ten times.
