Stepper motor is an electrical pulse will be converted into angular
displacement of the implementing agencies. Put it in simple language-speaking:
When the stepper drive pulse signal to a receiver, it drives stepper motor rotation
direction by setting a fixed point of view (and the step angle). You can control the
number of pulses to control the amount of angular displacement, so as to achieve
the purpose of accurate positioning; At the same time, you can by controlling the
pulse frequency to control the motor rotation speed and acceleration, so as to
achieve the purpose of speed.
Stepper motor directly from the AC-DC power supply, and must use
special equipment - stepper motor drive. Stepper motor drive system
performance, in addition to their own performance with the motor on the outside,
but also to a large extent depend on the drive is good or bad. A typical stepper
motor drive system is operated by the stepper motor controller, stepper motor
drives and stepper motor body is composed of three parts. Stepper motor
controller stepper pulse and direction signal, each made of a pulse, stepper motor-
driven stepper motor drives a rotor rotating step angle, that is, step-by-step
further. High or low speed stepper motor, or speed, or deceleration, start or stop
pulses are entirely dependent on whether the level or frequency. Decide the
direction of the signal controller stepper motor clockwise or counterclockwise
rotation. Typically, the stepper motor drive circuit from the logic control, power
driver circuit, protection circuit and power components. Stepper motor drive
controller, once received from the direction of the signal and step pulse, the
control circuit on a pre-determined way of the electrical power-phase stepper
motor excitation windings of the conduction or cut-off signal. Control circuit
output signal power is low, can not provide the necessary stepping motor output
power, the need for power amplifier, which is stepper motor driven power drive
