This should be a real engineering question, we can't give your clear answer since it's lack of enough information. That depends on the pole pair, the rated speed of the motor, the control algorithm you used, and the running performance you want. You have to do the evaluation by yourself if you want to get a further answer. 

Sir,

     I am  working on a motor with 2 pole pair ,rated rpm 95000  and control alogorithm used is speed control using instaspin_foc (PROJ_LAB05b)
