Effect # of poles on 3 phase motor current

Hello

Good morning

I want to clear my basics.

I know the formula for the speed of 3 phase motor is 120f/P.
So, if no of poles are increased then for a given frequency, the motor speed decreases and if the frequency is increased then for a given # of poles, the motor speed increases.

However, what is the effect on 3 phase motor current if no of poles are increased or decreased if while

1. The motor is running directly on 400 or 600Vac
2. The motor speed is controlled thru a VFD

Changing pole count affects current indirectly, mainly via motor design parameters and load torque-speed demands. But generally, More poles = lower speed, more torque = slightly higher current, Fewer poles = higher speed, less torque = slightly lower current

Basically the motor input power (voltage times current times power-factor) is determined by its power output, and is not largely affected by the number of poles or its speed, as long as the motor is operating in its normally efficient region of speed and voltage.
