Stepper motor

Convert electrical pulse signal into angular displacement of the stepping motor to control the micro &special motor rotors. As actuators in the automatic control device. For each pulse signal input, further before stepping motors, also known as the pulse motor. Stepper motor used in digital computer peripheral equipment, as well as the printer, plotter, and disk device.

Stepper motor is the electrical pulse signal into angular displacement or line open loop control elements of displacement. 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. Although the stepper motor has been widely used, but stepping motor does not like ordinary dc motor, ac motor under normal use. It must be driven by double annular pulse signal and power circuit of control system can use. So good with step motor is not easy, it involves the mechanical, electrical, electronic and computer and many other professional knowledge. Today, the manufacturer of stepper motor is indeed many, but has the professional and technical personnel, can be developed, developed at the factory are very few, most manufacturers only a, 20 people, even the most basic equipment. Only in a stage of blind imitation. This gives households in product selection, use lots of trouble.

Stepping motor driving power source by frequency pulse signal generator, pulse distributor and pulse amplifier, thus provide pulse current drive power supply to the motor windings. The performance of the stepper motor depends on the good cooperation between the motor and drive power supply.

Stepper motor is no cumulative error, the advantages of simple structure, convenient operation and maintenance, low manufacturing cost, the ability of stepper motor to drive the load inertia is big, suitable for small and medium-sized machine speed and accuracy is not high, defect is low efficiency, fever, sometimes out of step. Stepper motor is widely used in the digital control system, such as d/a conversion device, numerical control machine tools, computer peripherals, recorder, clocks, such as in the industrial automation production lines, printing equipment, etc are used.

Stepper motor is divided into electromechanical, magnetoelectric and linear three basic types.

Electromechanical stepper motor consists of core, coil, gear mechanism, etc. Will produce magnetic solenoid coil electricity, promote its core panels, through a rotary Angle of the output shaft gear mechanism, rotating the gear 天行健，自强不息；地势坤，厚德载物。1/5
