What will happen in the total phase current if the required ID flux weakening in flux weakening region does it takes more stator current

0 Venkatadri Shantaram84961 3 months ago

Hi,

Flux weakening limit can be configured, motor demands amount of Id required upto limit we set.

If ID is more, motor may stall based on the torque demanded by the load.

Phase current is Id**2+Iq**2 which clamps to limit we set.

Thanks and Best regards

How to set the optimal MTPA Id current for the ipmsm motor

0 Venkatadri Shantaram84961 3 months ago in reply to Karunakaran M

Hi Karunakaran,

You need to enable MTPA and then set the PERI_CONFIG1[SALIENCY_PERCENTAGE] , try different value until you see performance improving.

Before you start, keep LD=LQ in the parameter, device will calculate LD, LQ according to the SALIENCY_PERCENTAGE.

More information available in the datasheet.

Thanks and Best regards
