A stepping motor is an actuator that converts an electric pulse into an angular displacement. When the stepping driver receives a pulse signal, it drives the stepping motor to rotate a fixed angle in a set direction (this angle is called the æ© angle angle). ). We can control the angular displacement of the motor by controlling the number of pulses to achieve precise positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the purpose of speed regulation. "Phase" means that the stepper motor has several coils (also called windings). The “line†is to show that the stepper motor has several wiring ports. “Polarity†is divided into unipolar and bipolar. If the stepper motor's coil is bidirectionally conductive, then the stepper motor is bipolar. Conversely, if the stepper motor's coil is only unidirectionally conductive, then the stepper motor is unipolar. As long as you know the two of the above three, you can infer the third one. Such as: The five-wire four-phase stepper motor has five wiring ports and four coils. Since there are five terminals, that is, the number of terminals is an odd number, that is, one terminal is a common connector, the conduction mode of its coil is only allowed to be unidirectional, that is, the stepping motor is single. Polar. As shown below: The four-wire bipolar stepper motor has four wiring ports, and the conductive mode is two-way. Since there are four wiring ports and the conduction mode is bidirectional, this stepping motor is two-phase.
AC Contactor switch mainly used for making or breaking circuit at a long distance, suitable for controlling starting\stopping\reversing of AC motor. AC Contactor of korlen conforms to the requirement of IEC60947-4-1& GB14048.4 standards.
Except AC Contactor, there are many different types of low voltage electric appliances, such as Thermal Relay,Manual Motor Startor ,led light, Circuit Breaker, etc.
