Động cơ bước (Step Motor) hiện nay rất thông dụng trong nhiều ngành công nghiệp khác nhau. Ví dụ như sử dụng trọng hệ thống di chuyển của các lại máy cnc như máy cắt cnc, máy khắc cắt laser, máy cắt plasma cnc… A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motors position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an openloop controller), as long as the motor is carefully sized to the application in respect to torque and speed.
