4 FAQs about [Inverter variable frequency motor rated voltage]
What is an inverter duty motor?
An inverter duty motor is designed to run under the variable power conditions delivered by a Variable Frequency Drive (VFD). VFDs adjust motor speed by varying voltage and frequency, which saves energy and improves process control. However, standard motors can suffer from overheating and insulation failure when operated on a VFD.
Why do inverters need a variable frequency supply?
To avoid magnetic saturation and to obtain constant flux conditions in the machine, the voltage fed to the motor must also be varied. Therefore an inverter feeding a three phase motor must be capable of providing a variable voltage, variable frequency supply.
Can an inverter feed a three phase motor?
Therefore an inverter feeding a three phase motor must be capable of providing a variable voltage, variable frequency supply. The required voltage control can be obtained either external to the inverter or within it (Fig. 3.91).
What is a medium-voltage inverter-duty motor?
Medium-voltage inverter-duty motors with a base rating that exceeds 600 V must be able to withstand a peak voltage equal to 2.04 times the motor's rated line-to-line voltage. Rise times must equal or exceed 1 microsecond. Inverter-duty motors are also designed for wider constant-torque speed ranges than can be provided with a general-purpose motor.
