It is a motor where the frequency of the AC voltage is 50 cycles per second. In U.S.A. 60 Hz is standard. 50 Hz would be overseas.

Can you convert motor winding 50 hz to 60 hz?
60Hz frequency on 50 Hz motor will create more resistance in its coils. Will cause electromagnetic force trying to increase the speed of the rotor by about 20 %. Less current will flow but the torque will be less, because of the increased resistance of the coils. Usually if the motor is not loaded much it will work fine on 60 Hz. One solution if there is problem running the motor is to remove part of the all coils equally from all of the bobbins by 10-20% .CommentThe resistance of the coils will remain unchanged, however, their inductive reactance will increase -thus reducing the current.
Is it okay to connect 50 hz to 60 hz?
Assuming that you are referring to a piece of equipment designed for 60-hz power being connected to a 50-hz power line (common overseas), It depends on the application. If the load is a DC power supply, they are often rated for both 50 and 60 hz. If the load is a motor made for 60 hz, for example, it will run about 17% slower at 50 hz than at 60 hz due to the design of induction motors, and at higher current because of lower inductive reactance. If the load is fluorescent lighting, it may display an annoying flicker, and the ballasts will probably die an early death. If the load is transformer-powered, you'll have the same current problems as you get with the motor. OTOH, if you want to connect a 50-hz load to a 60-hz supply, it has its own issues. E.g., the motor will run faster and cannot be loaded as heavily. Best bet: research to see if the piece of equipment is rated for both frequencies.
Why does the rpm of a three phase motor decrease as the number of poles increase?
The synchronous speed is 6000 divided by the number of poles for a synchronous motor on 50 Hz, and 5-10% less than that for an induction motor. On a 60 Hz supply these speeds are 20% higher.
If you can Chang winding 50hz to 60hz?
If you have the motor rewound you could possibly have it changed. You can run some 50 hz motors on a 60 hz system but there are no guarantees. The motor will run faster and there is a chance it will overheat. There is no way to change the field connections of a motor to accomplish this. Best bet is to just purchase the correct motor.
Can you use 50hz insted of 60hz?
I've seen it done, but be certain that the motor is connected to the correct VOLTAGE. The UK uses a 50Hz, 240V electrical system. The US uses a 60 Hz, 120/240V. The motor you are referring to was probably used in the UK, so will probably need 240V.
What will happen 50 HZ motor when you will give 60 HZ?
motor will run at a faster rate.....

Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
A 6 pole induction motor is connected to a 415v50hz mainsIt runs at a speed of 960 rpmCalculate the answer of synchronous speed?
Answer 1000 RPM or 16.667 HZ, 50 Hz * 60 = 3000 RPM 3000 / 3 = 1000 RPM, or 50 HZ / 20 (1/3 of 50 Hz) * 60 seconds. Or Hz * 20 ( converts to RPM) For 4 pole then, Hz * 30 = RPM For 8 pole, Hz * 15 = RPM
What is dsadvantages of having 50 Hz supply over 60 Hz supply?
There is no inherent disadvantage of 50 Hz compared with 60 Hz, bearing in mind that systems that run at 50 Hz are designed to run at 50 Hz.
How do you run a 460 volt 60Hz motor with 460 volt 50Hz power?
If 50 hz is applied instead of 60 Hz, the speed of the motor will reduce by 10 hz equivalent. If you still want to keep the output speed equivalent to 60 Hz, you will have to use suitable gear box or so, to increase the speed to 60 hz equivalent.
If a motor designed for 50 or 60 cycle operation is connected to 60 hz current the motor will what?
The motor, being designed to run on either a 50 or a 60 cycle (a.k.a. hertz) system , will turn faster.
Can you operate a motor of 575 v 60 Hz with a power supply of 575v 50 Hz?
Yes, it will just run slower than rpm indicated on nameplate

Can a 415V 3-phase 50 Hz motor run on 380V 3 phase 60 Hz?
Yes, it will run drawing little more extra current in similar conditions. The motor is expected to be running in lesser rpm as well.
Can I run a 220 volt 50 hz motor with 220 volt 60 hz supply?
Yes. It will work OK but run about 20% faster than the name plate indicates.
