Nettet10. jan. 2016 · On a VFD, frequency is speed, but current is torque. 100% rated current is essentially 100% rated torque regardless of the speed. However, 100% rated current means 100% rated heat, but now with only half the cooling air from the shaft-mounted cooling fan. Your motor may (or may not) be rated for this. Check with the manufacturer. NettetTo calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM. You can also calculate the slip rating by ...

NettetThis is exactly what will happen in this case. It will run with following problems for a 50Hz motor running on 60Hz: The core loss will increase and cause over heating of core. As the core loss will increase, the Power Factor of motor will reduce. The motor speed will be higher, so shaft load will increase. Motor will be overloaded at rated load.
