Mains voltage and frequency differ around the world, and they directly affect compressor motor speed and output. Specifying the correct power supply prevents motor damage and lost performance.
Why Voltage Matters
- 380V/50Hz is common in China, Europe and much of Asia.
- 460V/60Hz is common in North America.
- The motor must be wound for your supply voltage.
How Frequency Affects Flow
- A 60Hz motor runs about 20% faster than a 50Hz motor.
- Faster speed means higher flow for the same machine.
- Always confirm the FAD at your local frequency.
Specifying Your Supply
- Tell the supplier your voltage, phase and frequency.
- Confirm starting method and control voltage.
- Allow for voltage variation in your area.
Can I run a 380V/50Hz machine on 460V/60Hz?
No. The motor must match the supply. Running on the wrong voltage or frequency can damage the motor.
