Supply Voltage & Frequency

The Motors can be wound for any voltage from 200 volt to 660 volt and for either 50 Hz or 60 Hz frequency. Standard motors are wound for 3 phase, 415 volt, 50 Hz supply condition.

The Motors can also be supplied for dual voltage operation or for operation with variable voltage and variable frequency supply(VVVF),or for operation over a wide voltage range. Separate ‘VD’ series of motors suitable for VVVF drive are specially designed to withstand higher dielectric strength to combat voltage surges originated from high switching frequency with IGBT drives.

The supply voltage is assumed to be virtually sinusoidal and balanced as defined in IS 325.
