Frequently it is necessary to connect three-phase not ors to single-phase mains. In this connection, the following disadvantages must be taken into account. The rated output (see rating plate) will be reduced to 80 % to 65 %.
The rated torque will be reduced to 30 %.
The output or power can be calculated according to the following equation:
C = capacity of the capacitor in μF
P = power in kW
U = voltage in V
f = frequency
The following approximate values can be assumed when connecting to single-phase alternating current of 220 V:
| Power (kW) |
