Stepper motor

Stepper motors at NKX Motor. We offer a wide selection of the most diverse types of stepper motors in standard Nema dimensions, intended for both hobby and industrial applications. The most commonly used stepper motors are Nema 17, Nema 23 and Nema 34.
A stepper motor is basically a brushless DC electric motor that divides a full revolution into several smaller steps. The distance between the steps is determined by the distance between the toothed electromagnets, which are arranged like a stator around the central rotor. The electromagnets are powered by an external driver circuit. To rotate the motor shaft, the driver sends current through a single electromagnet that magnetically attracts the rotor teeth. When the rotor gears are aligned with the first electromagnet, they are slightly offset from the next electromagnet. This means that when the next electromagnet is turned on and the first one is turned off, the shaft rotates slightly to align with the teeth of the next electromagnet. Then the process is repeated. In this way, we can very precisely control the rotation angles of the stepper motor, which is their biggest advantage.
For the proper operation of the stepper motor, we need more controller, stepper motor driver and power supply.
