I saw a synchronous belt drive motor, and his precision is quite high. But with two lines, will it be a stepper motor?
Stepper motor is an induction motor, its working principle is the use of electronic circuit, the DC power supply variable components, multi-phase timing control current this current stepper motor power supply, stepper motor can work normally, the power supply for the stepper motor driver is divided into the multi phase sequence controller.
The use of 220V AC motor is actuated in single phase two wire stepper motor.The stepping motor is an open loop control element which transforms the electric pulse signal into angular displacement or linear displacement. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. Number of pulses can be controlled by controlling the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.
Although the stepper motor has been widely used, but stepper motors can not be like ordinary DC motors, AC motors in the regular use. It must be composed of double ring pulse signal, power drive circuit and so on, and the control system can be used. Therefore, it is not easy to make good use of stepping motor. It involves many specialized knowledge, such as mechanical, electrical, electronic and computer. Stepping motor, as an actuator, is one of the key products of mechatronics. It is widely used in various automatic control systems. With the development of micro electronics and computer technology, the requirement of stepping motor is increasing day by day, and it is applied in every national economic field.
Yes, use 220V alternating current electric motor is in the single-phase stepping motor, 50 rpm, the reducer driven clock, it only when accuracy and power supply frequency.There are some electric fans in the motor used to shake the head, but also single-phase stepper motor.What's more, the stepping motor in the current quartz clock is also a single-phase, a positive pulse and a negative pulse, two seconds to turn a circle,As for the motor that you say is stepping motor, you can lower the supply voltage. If you are stepping motor, lower the voltage, can not change the speed, and the asynchronous motor will slow down.
