Rated motor voltage: 230/400 V - 3 ph - 50 Hz
System voltage:
276/480 V - 3 ph - 60 Hz - 2 & 4 poles (motor voltage + 20 %)
System voltage:
265/460 V - 3 ph - 60 Hz - 6, 8 & 12 poles (motor voltage + 15 %)
If a 50-Hz motor with a 20 % higher voltage is operated on a 60-Hz supply system, frequency
and speed increase by 20 %. But except for minor deviations, the rated motor parameters
remain constant (V/f constant).
If the supply voltage is increased by 15 % compared to the motor voltage, the actual motor
output decreases to 92 % of the original motor output.
In this operating mode, the drum motor should have an output reserve of at least 20 %.
Supply voltage = 1.2 x rated motor voltage (for 2 and 4 number of poles)
