The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
Motor speed formula:
N = 60f / p
In the above formula
N - the speed of the motor (r / min);
60 - per minute (s);
F - power frequency (hz);
P - pole pairs of motor rotating magnetic fields.
Hello, poles (a pair of pole) motor, the theoretical speed of 50 rpm when the theoretical speed of 3000 r / min, if the display shows only 1500 rpm, it is possible to have a motor shaft speed or speed device Yeah, gear ratio of 2 to 1 ,
The speed displayed on the display may be the speed of the deceleration or transmission. It is also possible that your inverter parameter ratio is not set, you need to modify and adjust, you want to help.
