facing a problem while driving PMSM Motor using STM32303E-Eval and STEVAL-IPM20B motor driver board for FOC sensored(encoder) method

While driving PMSM motor using STM32303E-Eval with IPM20B driver card, Motor is jerking and spinning abnormaly. I am using sensored feedback method such as encoder having 1024 ppr.

Hello ​@vishu,

Verify the motor U, V, and W phase connections, the encoder connections, and both board settings (the jumper and solder bridges mentioned in the MC Workbench tool, in the Pins Usage & Hw Changes > Hardware Changes tab).

Use the main speed sensor as sensorless STO-PLL and the encoder as the auxiliary sensor. Verify that both electrical angles, STOPLL_EL_ANGLE and ENCODER_EL_ANGLE, are aligned.
