Basic knowledge of the stepper motor

Stepper motor, stepper motor, or pulse motor, etc... With all kinds of call way, these with the Japanese words to said, became a step motor, and order is stage step by step action meaning, this use another language to say, is to be stepping driving means, in short, is a pulse input there will be a certain Angle, the distribution of rotor displacement motor.

Stepper motor's brief introduction:

Stepper motor is the electrical pulse signal into angular displacement or linear displacement of open loop control components.

In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, which give the motor a pulse signal, a step from the Angle of motor is turning.

This line sexual relations, and the error of the stepper motor only periodic without cumulative error, etc. Made in the field of speed and position control with stepper motor to control becomes very simple.

Single-phase stepper motor has a single way electrical drive, power output is generally small, the purpose for small power drive. Multiphase stepper motor with multiphase square wave pulse drive, quite useful. Using multiphase stepper motor, single-channel electrical pulse signal is converted to a multiphase pulse signal can be through the pulse distributor first, after the power amplification, respectively, into the stepping motor each winding. For every input pulse to pulse distributor, motor current state of each phase is changed, the rotor turns an Angle (called the step Angle). Under normal circumstances, the stepping motor turned is directly proportional to the total number of Angle and the input pulse; 

Continuous input a certain frequency of pulse, the speed of the motor keep strict corresponding relation with the frequency of the input pulse, not affected by voltage fluctuations and load change. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, which give the motor a pulse signal, a step from the Angle of motor is turning.
