A stationary induction motor can be represented by an equivalent circuit consisting of the following components:
1. Stator winding: The stator winding is represented by a series combination of resistance (R1) and leakage reactance (X1). This component represents the electrical resistance and inductance of the stator winding.
2. Rotor winding: The rotor winding is represented by a series combination of resistance (R2) and leakage reactance (X2). This component represents the electrical resistance and inductance of the rotor winding.
3. Magnetizing reactance: The magnetizing reactance (Xm) represents the magnetizing inductance of the motor, which is responsible for creating the magnetic field necessary for motor operation.
4. Core loss resistance: The core loss resistance (Rc) represents the losses in the motor core due to hysteresis and eddy currents.
5. Mechanical load: The mechanical load is represented by a resistance (Rm) in parallel with the rotor winding. This component represents the mechanical losses in the motor due to friction and other factors.
The equivalent circuit of a stationary induction motor can be represented as follows:
