Electrical Motor Supply Distribution System

Electrical Motor Supply Distribution System

The electrical  Motor supply distribution system must supply the correct voltage

and have sufficient capacity to start and operate the motor load.

Voltage and Frequency

- Motors are available in standard voltage ranges:

- Single-phase motors are rated for 120/240 volts @ 60 Hz

- Three-phase motors up to 100 HP are available for 208-230/460 or

575 volts @ 60 Hz.

- 125 HP and up – 460, 575, 2400 or 4160 volts @ 60 Hz

- Other voltages and frequencies can be ordered to meet special requirements

- Single-phase and three-phase motors are designed to operate

successfully with voltage variations of +/- 10%.

- Phase unbalance must be less than 1% for proper motor operation.

Phase unbalance leads to excessive temperature rise and a rise to the full load amps of the motor.

- Frequency variation of up to 5% is permitted for normal motor

operation. Motor speed varies directly with the frequency of the power supply.
