Motor flux factor map showing slip versus magnetising current
factor. Used to give additional torque at low speed.

2. Use the motor name plate data and the self characterization routine provided by Gen4 and
DVT (described below).
The flux vector variant of software includes motor temperature compensation which can be used
to adjust rotor resistance (4641
h
,8) with motor temperature. This is set at 4621
h
,4 to 7.
Self characterization
WARNING: The self characterization function will cause the motor to operate. Always
ensure the vehicle is jacked up, with the driving wheels off the ground and free to turn
before starting the test.
The motor self-characterisation process allows a user to determine the electrical parameters
required for efficient control of AC induction motors using a Gen4 controller connected to a PC
or laptop running characterisation software. For further information, please contact your local
Sevcon representative.
