WebDescription The Squirrel Cage Induction Machine can be operated in either 'speed control' or 'torque control' modes. In speed control mode, the machine rotates at the speed specified at the input W. In torque control mode, the speed is calculated based on the machine inertia, damping, the input torque and the output torque. WebFrom the above equation, the speed of the motor depends on supply voltage (V), Flux (Φ), and Armature resistance (Ra). Therefore, the speed of a DC motor can be varied, changed and controlled by changing; Terminal voltage “V” (AKA Applied Voltage Control Method).
