Voltage
Motors are designed to run at the voltage listed on their nameplate. Many industrial motors are designed to run at more than one (line power) voltage. For example, many motors are dual rated and are designed to run at 230V and 460V.
Typically, motors have an operating tolerance of 10%± of the rated voltage on the nameplate (consult your manual). This means that a motor designed to run on 230V can run at 208V (or 240V). Motors should not run outside their designated voltage range, doing so will damage your motor and or equipment. When working with a motor rated for dual voltages don’t forget to verify the corresponding amperage rating and lead connection
