60Hz to 50Hz Frequency Converter

As a controls systems engineer, and in dealing with frequency converters for over 25 years, a frequency converter with motor regulating capabilities and adjustable to 50 Hz or 60 Hz outputs regardless of the Hertz input, the AC motor speed ratio can be set nearly precisely and regulated to within plus/minus 0.5% of selected motor speed without an encoder, depending on the quality of the frequency converter. A good frequency converter will also regulate the voltage output to match the 20% difference figure between 50Hz/400V VS 60Hz/480V applications, with a resulting boost in torque and HP from a 50Hz to 60Hz power supply. It's the ability to provide the balance that affords peak performance and efficiency from the motor. Keep in mind the power grid, if this is where the system is intended for use, is anything but precisely uniform in voltage levels. Frequency converter capability to output the selected Hz and V, while regulating precise motor speed, regardless of the Hz input is very commonly done with frequency converter.Frequency Converter 60Hz to 50Hz

Can a three phase 380V 50Hz motor running on 460V 60Hz power supply?
Having worked for a major motor manufacturer the difference between a 50Hz motor and a 60Hz motor is what was printed on the nameplate! For a more technical explanation, please consider that 380V/50Hz = 460V/60Hz or 7.6V/Hz which is the key to AC motor operation. Using a 60 Hz motor in 50 Hz power supply will change the nameplate speed.

Another way to think of it is to imagine you were in a 60Hz supply using a frequency converter. Running the motor at 50Hz the frequency converter would be supplying around 380V to the motor.

The motor will be fine at three phase 460V 60Hz no difference then 380V 50 Hz as long as the increased RPM does not increase the application load beyond the limits of the application or the motor. This can occur in a variable torque application like centrifugal fan or pump. If over loaded, you can reduce the load by changing pulley ratio, restrict flow or add a frequency converter to name a few.

For some applications need specific Hertz and Volts, you can buy a GoHz frequency converter for both single phase and three phase with a reasonable price, then you can convert Hertz from 40 Hz to 499.9 Hz, volts from 0-300V single phase and 0-520V three phase, for example:
Convert single phase
110V 60Hz to 220V 50Hz;
230V 50Hz to 110V 60Hz;
120V 60Hz to 240V 50Hz;
... ...
Convert three phase
480V 60Hz to 400V 50Hz;
380V 50Hz to 460V 60Hz;
... ...
Both Hertz and Volts are adjustable in separate with better output pure sine wave.
