3.7.2 Types
The electric motors which can be connected to the mains electricity supply normally have
on the motor plate one of the following voltage specifications:
• Motor 230 V~ : 230 V. Single phase motors which are connected between the live
and the neutral or on 230V between the phases.
• 230/400 V : These motors can be connected in a circuit of 230 V between the
phases. The windings are then in a delta configuration (see figure 7). In a circuit with
400 V between the phases, the windings are in a star configuration (see figure 8).
