Can you run a 460v 60hz motor to a 480v supply?
The the supply stays within +/- 5% of what the motor is rated for, you can do this.
3 phase reverse relay can be utilized for motor control speed?
3 phase reverse relay can be utilized to control 480V motor 60HZ for controlling their speedspeed.
How can you determine if an electric motor is 50HZ or 60HZ if there is no name plate?
One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.
Can you use a 480V 60hz deep fryer on a 380v 50hz power supply stepped up to 480v 50hz by a transfomer?
It is an extremely expensive way of utilizing the deep fat fryer. You should look into changing the heating coils in the fryer to utilize the new voltage. That said it can be done.
Can you run a 460v 60hz motor to a 400v supply?
yes can run but motor only delivers 90%rated power because v/f less by 10%

Can a 440 - 480V 60Hz motor run in a site with 380V 60Hz supply If No how can it work?
The motor will run, probably at nearly the same speed, but it cannot supply the same mechanical load. If it can be run on a lighter load, proportional to the voltage, it should be OK.
Can I run laundry equipment 440V 60hz 3 pH on a 480V 60Hz system?
This should not be a problem but check with the manufacturer of the laundry equipment to be certain.

What is impact ampere in 50Hz motor connected to 60Hz?
What effect will be there on the motor (Induction) output power when a 100kW 50hz motor is connected to a 60hz power supply.
Can a vfd be run any higher than 60hz?
Yes, most VFDs can run faster than the input power frequency so you can run a motor to 60Hz with a 50Hz power source. Just be aware that as speed increases, so will the current. Also be aware that a motor is rated to run a specific rpm and running faster may cause motor bearing failure after a short time.
How can you run a 380v 50hz motor with 440v 60hz source?
Yes. It will make your motor a little faster though, so it depends on what you are powering with this motor. IE Can the piece of eguipment be ran faster?
How will work motor 460V 3ph 60Hz at 380V 3ph 50Hz power net?
It will not work at all.
Will a 230V 50Hz drain pump of a washing machine work on a 220V 60Hz?
No! Normally not, the recistance in the windings is to hig on 60Hz and the pump motor has not power enough to work propelly. This happened to myself when I connected my Whirpool AWE 7519 to 230V 60Hz. Europian model for 50Hz.
