Title:
Stepper Motor Control with dsPIC DSCs
Name:
AN1307
Date:

Author:

Description:
This application note demonstrates the advantages of using dsPIC33F motor control family DSC to drive stepper Motors. Particular methods of using higher voltages to achieve high torque, accurate micro-stepping, and an increase in maximum motor speed are presented. A comparison is made between the classical open loop approach and the closed loop current control mode. Eight PWM channels are used to control a stepper motor in all possible ways, whether it is bipolar or unipolar, using full step or microstepping, open or closed loop, without the need for external jumpers or complicated logic circuitry. Note: Please refer to AN907: Stepping Motor Fundamentals for information on the types of stepper motors, microstepping and current limiting techniques.
