Have you ever wondered what is the difference between the electric motors included in those two Development Kit with S12 MagniV?

 

 

MTRCKTSBNZVM128: 3-phase Sensorless BLDC Development Kit with S12 MagniV S12ZVM

MTRCKTSPNZVM128: 3-phase Sensorless PMSM Development Kit with S12 MagniV MC9S12ZVML128 MCU

 

Well frankly writing none. They include the same motor model 45ZWN24-90       .

So the motors are same from physics perspective, only the flux distribution in an air gap is different. It is sinusoidal for PMSM whereas it is trapezoidal for BLDC motor.

The powerstage is same for both but what is different however is the control strategy.

The Linix motor equipped with the DevKits is in fact somewhere between PMSM and BLDC, The flux is not sinusoidal nor trapezoidal.
