Which example project did you base? svgen_dq is independent of the pole pairs of a motor, even any parameters of a motor. You might check if other modules which are related to the pole pairs of a motor and change it to the right one.

Hi Yanming,
First of all thank you for your reply. yes, svgen_dq is independent of the number of poles. However, I notice noises in the 14P engine that I do not hear with the 8P engine (i hear nothing with the 8P). I notice either a background noise or a clattering according to the parameters i do not notice with 8P that is without noise.
I precise that i notice this phenomenon in open loop: I change the angle theta by constant step, fixed flux value D to zero and torque value Q to a fixed value before to call arm_inv_park_q31 to get Ualpha and Ubeta.
An assumption: About clattering noise, It seems that the engine runs on 2 phases. When I manually brake the engine this slam decreases or even disappears Maybe would you know eventually how to phase out the signals in svgen_dq algorithm ? or another assumption.

another assumption is a maybe delta connected motor 14P versus a star connected 8P motor

Did the motor spin with the same mechanical frequency, or electric frequency to measure noise? You may try to use different PWM frequency for these two motors, to implement a higher PWM frequency for the 14P motor.
