Different between 50hz and 60hz generators?
Will it cause more damages than to the system?
Answer:
The guy above has it backwards. We're 60Hz here in N.A. Most of the rest of the world is working at 50Hz.
Answer: depends upon the design of the motor. Many kitchen appliances, inexpensive power tools and vacuum cleaners use a "universal" motor that will work acceptably at either frequency. You'll find these as somewhat noisy, using carbon brushes. The rating plates should show that they're OK for 50/60Hz use. HOWEVER: You won't find one of these in ANY air conditioner!
If you drive an induction motor designed for 60Hz at 50Hz, it will run slower, at a significantly increased current, and due to the latter, will run hotter - quite possibly hot enough to do some real damage if under a fair percentage of the motor's rated load. Ideally, a reduction in frequency should be matched with an proportional reduction in voltage in order to avoid this. One method is to use a step down transformer to reduce the voltage. Use the 168J from the link below with the 95V tap, and you've got 2KW to play with... enough to run your AC unit at 95V/50Hz.

Hope that helps.
I honestly should know this, since i am taking heating and air classes. But i dont.
Damn i need to study.
But i think that 60 hz is used in most european countries and 50 is used in America, and yes-60 hz would probably damage a 50 hz system.
But then again i could be way off.
Ten hertz difference comes from a different engine speed. I have to assume you are looking at 220/240 volt single phase units.
A motor rated for use at 60Hz probably lists 1760 as synchronous rpm. At 50Hz it will turn something like 1450. If the torque (voltage) were the same the hp is reduced. Motor cooling might be an issue depending on the duty cycle.
Variable frequency (speed) drives output the programmed frequency whether powered at 50 or 60 hertz. Some VFDs can take single phase power and output 3-phase.
Check the air conditioner input power requirements. At 50Hz the compressor will run slower = longer and the blower will run slower = colder air but not as much. AC control unit might not be happy.
