2 pole 0.75 kW motor can increase the speed through the inverter?
if the 4-pole motor to rise to 2-pole motor frequency, The frequency of the motor rises to about 100 Hz, which is easy to implement for the frequency converter.
2-pole motor speed of about 2900 r / min or so, 4-pole motor speed of about 1400 r / min or so, which are in the case of 50HZ,
