Stepper motor use precautions
Stepper motors of different specifications should select the corresponding driver. The phase, power supply mode, voltage and current of the driver meet the needs of the stepper motor.
Precautions
1. Stepper motors of different specifications should select the corresponding driver. The phase, power supply mode, voltage and current of the driver meet the needs of the stepper motor. The driving power of the stepping motor is mainly composed of a pulse generator, a pulse distributor and a pulse amplifier (also called a power amplifier). The MCU sends commands to control the stepper motor by controlling the driver. The pulse generator is a pulse signal generator whose pulse frequency is continuously variable from a few Hz to several tens of kilohertz. According to the instruction, the pulse distributor applies the pulse to the power amplifier of each phase winding according to a certain logic relationship, so that the motor operates in a certain manner to realize the forward, reverse and positioning.
2, the control method of the stepper motor, take the three-phase stepper motor, not only the three-phase three-shot method. It is also possible to implement a three-phase six-shot method in software. The three-phase six-shot method is half the step angle of the three-phase three-shot method. For example, the three-step step angle is 30 degrees, and the six-shot step angle is 15 degrees. This means of improving the accuracy of the step angle is called subdivision.
3. The instruction used in the above code is STC89C52 MCU. If you need to use other chips, please change it separately.
