What is the maximum allowable variation from the motor nameplate voltage?

The maximum allowable variation from the motor nameplate voltage is ±10%. This standard is in place to ensure the efficient and safe operation of electric motors. When the supply voltage stays within this range, it helps prevent overheating, excessive current draw, and potential damage to the motor and other connected equipment. Operating outside this voltage range can lead to reduced performance levels, increased wear and tear, and can potentially shorten the lifespan of the motor. Therefore, maintaining a voltage variation of ±10% is critical for optimal functionality and longevity of electric motors used in commercial food equipment.
