In speed torque curve of Induction motor lab module of Motor CAD constant torque region is not going into constant power region at the base speed. What is to be done? For the speed torque curve Maximum speed is to be specified...How to specify it

[Howard]

For peak performance of constant torque and power, it would calculate peak capability of the electrical machine with voltage and current limit.
If it is over-designed, the constant torque region will exceed the required base speed. It is a design problem. Please modify the design.
However, there are two options.
1). Power limit, in Lab->Electromagnetics, could limit power for the map.
2). Thermal, in Lab->Thermal, could create continuous and peak thermally constrained operational envelope. Please check both in the manual. Thanks.
