स्टेपर मोटर का कार्य सिद्धांत क्या है?

एसtepping motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the motor speed and stop position only depend on the frequency and pulse number of the pulse signal, and are not affected by the load change. When the stepper driver receives a pulse signal, it drives the stepper motor according to The set direction rotates a fixed angle, called "step angle", and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, to achieve the purpose of accurate positioning; at the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, achieve the purpose of speed regulation.

एसtepper motor is a kind of induction motor. Its working principle is to use an electronic circuit to transform direct current into la time-sharing power supply. Multi-phase sequential control current. Use this current to supply power to la stepper motor, and la stepper motor can work normally. The driver is a time-sharing power supply for the stepper motor, a multi-phase sequential controller.

Although the stepper motor has been widely used, the stepper motor is not like an ordinary DC motor, and the AC motor is used conventionally. It must be composed of a double ring pulse signal, power drive circuit, etc. to form a control system before it can be used. Therefore, it is not easy to use a stepper motor well. It involves much professional knowledge such as mechanics, electric motors, electronics, and computers. As an executive element, la stepping motor is one of the key products of mechatronics and is widely used in various automation control systems. With the development of microelectronics and computer technology, the demand for stepper motors is increasing day by day, and they are applied in various fields of la national economy.
