Connecting the motor to the inverter in a star or delta connection

Standard induction motors with a rated power of approximately ≤ 3 kW are normally
connected in a star/delta connection (Y/Δ) at 400 V/230 V. For a 400-V line supply, you can
connect the motor to the inverter either in a star or in a delta connection.

The motor goes into field weakening above
the rated frequency. In field weakening, the
available motor torque decreases linearly with
1/f. In field weakening, the available power
remains constant.
