The relationship between the step motor drive and the controller and the encoder
Stepper motor actuator, as power drive, the encoder is stepping motor's speed and position feedback to the controller, the controller according to the feedback information to make decisions and to control the step motor, thus forming a closed loop control system, connect with each other; The step motor is an open loop controlling element which converts the electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.
The step motor is controlled by pulse voltage, not ordinary sinusoidal alternating current. Is it going to be the controller. How much of a step motor is going to be done with an encoder.
A step motor is an actuator that has the ability to control the Angle of rotation, the direction, or the number of turns. The actuator is a power amplification system that accepts the number of pulses and the rotation direction of the step motor. The controller accepts the encoding instruction, the man-machine dialogue, and the change of the instruction to the central component of the drive. This is where the coder detects the Angle of rotation of the motor, the direction, and feedback to a detector element in the controller.
