Summary
This dsPIC33F/E application note describes a motor
control technique where a single-shunt resistor circuit
used to measure the motor phase current. The algorithm
reconstructs all three phase currents which are then used
to estimate the rotor position in Sensorless Field Oriented
Control (FOC) of Permanent Magnet Synchronous Motors
(PMSM). This algorithm also corrects the PWM waveforms to
compensate for the changes made to take the phase current
readings.

Single-Shunt Three-Phase Current Reconstruction Algorithm
for Sensorless FOC of a PMSM
Summary
This application note describes how to drive a stepper
motor with a dsPIC33F/E motor control family DSC. PWM
outputs are used to control both unipolar and bipolar
stepper motors. Full stepping, half-stepping or variable
micro-stepping is supported, in open or closed loop mode
with a variety of decay modes. The application note software
includes a MPLAB IDE DMCI /RTDM file that providing an
easy to use GUI for selecting the stepping mode, open
or closed loop operation, the decay mode and a “step to
position” command.
