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.

Why A synchronous motor is sometimes called a synchronous capacitor Explain?
A synchronous motor can operate as either a Generator or a Motor.When a synchronous motor has current applied to the windings on its rotor and the stator is energized with say a 50hz line supply (with little or no physical load) then the exact amount of excitation provided by the rotor can determine whether the stator displays inductive or capacitive properties.If the rotor is under excited (too Little rotor current) the Synchronous Motor will behave as an Inductor, however if the rotor is over excited then the Synchronous Motor will behave like a Capacitor.Hope this helps
Will a 240v motor run on 220v power?
yes, the voltage and frequency are both nominal. As long as your within 10% of the rated voltage and frequency of the name plate you will be good. 50Hz and 60Hz are not within 10% of each other. I do not think it will work. u also run the risk of burn out because it will run faster
Can you use a 240v 50hz drill in a country that uses 220v 50hz?
There should be no problem at all.
How do you reduce the speed of a single phase digital meter 1600mp or kWh 50HZ without reducing the consumer load?
The speed of a single phase digital meter 1600mp or kWh 50HZ can be reduced. By decreasing the voltage to reduce the speed of the single phase digital meter the motor is to decreased in speed meaning the consumer load will be decreased as well.
How do you calculate the cost of electricity bill of a 3 phase 125kW induction motor running at 400v 50Hz motor running for 8 hrs condition if 1000w equal to Rs0.238?
To answer this question, i need the power factor of the motor.CommentYou don't need the power factor, as you already know its true power (watts), but you do need to know the efficiency of the motor to determine its input power. You also need to know the cost per kilowatt hour.But you can get a rough idea by multiplying the number of kilowatts, by the time in hours, by the cost per kilowatt hour. For a more accurate answer, you need to divide this by the efficiency of the motor.

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.
What size of wire should i use with a 50hz motor?
Depends on the current rating which should be on the motor.
Will a 500volt 50hz squirrel cage motor run on 380volts 50hz?
No, the voltage of 500 volts is too high to operate a 380 volt motor.
What size of generator to run 5.5kw 400v 50Hz motor?
You need a 5.5kw generator to run a 5.5kw motor.
How can you operate a electric motor rated at 400V 3phase 50Hz on a 400V 3phase 60Hz system?
Yes, however, the RPM will increase by 20%, if the motor is connected to a shaft or driving something that can not handle the torque, then you might run to heating issues or performance issues.
How can you operate a electric motor rated at 400V 3phase 50Hz on a 480V 3phase 60Hz system?

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?
