Characteristics of motor power and motor torque

The maximum motor power dependents on the available HV voltage.

Example: Motor power at 600 VDC and 500 VDC / - - - field weakening area

The transition into the field weakening (characteristic speed point) collaborates with reduced HV voltage earlier.

The maximum motor torque falls generally in field weakening. In addition, the torque falls with reduced HV voltage.

Example: Motor torque at 600 VDC and 500 VDC / - - - field weakening area
