Product Description
Since the formula for governing synchronous speed of a three-phase motor is = [(120*Hz)/# Motor Poles], if this is a 4-pole motor, the speed will be 1500 RPM at 50 Hz and 1800 RPM at 60 Hz. Since motors are constant torque machines, applying the formula HP = (torque*RPM)/5252 you can see that with a 20% increase in speed the motor can also produce 20% more horsepower. The motor can produce rated torque at both frequencies valid only if the V/Hz ratio is constant; this means that at 50 Hz the supply voltage should be 380 V and at 60 Hz the supply voltage should be 460 V. In both cases, the V/Hz ratio is 7.6 V/Hz.
