Abstract
This chapter is to illustrate the method that uses the constant Volts Herts (V/F) and the slip speed to control the ACIM torque. It is known as the scalar torque control. This technique can achieve satisfactory torque accuracy, but it usually comes with slow dynamic response.

Notes
- 1.
Asymmetry between motoring and generating is explained in Chap. 2.
- 2.
Relocation of the middle branch to the stator terminal is equivalently an implicit relocation of the stator resistance and leak inductance.
- 3.
The full model can be either from direct calculation of the equivalent circuit in a sense of the full representation, or equivalently, from the Thevenin’s transform.
