Basic Introduction of Stepping Motor
As an actuator, stepper motor is one of the key products of mechanical and electrical integration, widely used in a variety of automated control systems.
With the development of the microelectronics and computer technology, the demand of stepper motor is daily on the increase in applications over the national economy fields.
Stepper motor is an electric pulse that into the angular displacement of the actuator.
Popular point is that when stepping the driver receives a pulse, it drives stepper motor to rotate along the direction set by a fixed angle (step angle).
You can control the angular displacement by controlling the number of pulses , so as to achieve accurate positioning purposes and can be
controlled via a control pulse frequency motor rotation speed and Acceleration, so as to achieve the purpose of speed.
