Stepper motor is known to all, stepper motor is different from general motors, can use plugged in. Stepper motor can run digital signal control, only when the pulse provided to drive, in too short time, the number of pulses control system announced too much, also is the pulse frequency is too high, will lead to plugging a stepping motor. To solve the the problem of blocking a stepping motor, deceleration control measures must be adopted. In stepper motor started to gradually increase the pulse frequency, pulse frequency demand gradually slowing. This is what we call the & other; Deceleration & throughout; Methods. Stepper motor speed, which is based on the input pulse signal changes to change. As long as give drives a pulse signal, then the stepper motor is a step away from the Angle of rotation, if the pulse signal changes too fast, step motor as the internal damping effect of back electromotive force, magnetic reaction between rotor and stator will follow electrical signal changes, will lead to the blocked and steps. Thus stepper motor in high speed startup, demand the pulse frequency up to also have to slow down the process when suspension, to ensure implementation stepper motor fine positioning control. Speed up and slow down the principle is the same. To solve the the problem of blocking a stepping motor, deceleration control measures must be adopted. In stepper motor started to gradually increase the pulse frequency, pulse frequency demand gradually slowing. This is what we call the & other; Deceleration & throughout; Methods.
