A stepper motor, also known as a pulse motor, is a type of electromagnet that can rotate freely based on the most basic principle of electromagnets. Its action principle relies on changes in air gap magnetic conductivity to generate electromagnetic torque. Its original model originated from ***0 to ***0. Attempts to control began around ***0 and were applied to the electrode transport mechanism of hydrogen arc lamps. This is considered the initial stepper motor. In ***3, James Weir French invented the three-phase variable reluctance type, which was the predecessor of stepper motors. At the beginning of the *0th century, stepper motors were widely used in automatic telephone exchanges. Due to the Western capitalist powers competing for colonies, stepper motors were widely used in independent systems such as ships and aircraft that lacked AC power. In the late ***0s, the invention of transistors gradually applied to stepper motors, making digital control easier. After the ***0s, due to the emergence of low-cost microcomputers in a multifunctional manner, the control methods of stepper motors became more flexible and diverse.
