Induction Motor by Bullet Points. Stator generates rotating, sinusoidal B-Field: . This field induces current in the rotor cage loops at . The stator B-Field at each rotor wire is such that . Torque pushes in direction of field rotation! . Section 34. To determine . mutual. inductance, we neglected the thickness of the linear conductors. . To determine . self. inductance, we must consider the finite size of the conductor. Otherwise . A generator is the opposite of a motor – it transforms mechanical energy into electrical energy. This is an ac generator:. The axle is rotated by an external force such as falling water or steam. The brushes are in constant electrical contact with the slip rings.. Induction Motors Equations, Performance, Electrical Equivalent Circuits Stator Structure: Single Winding and One Turn Rotor Induction Motor by Bullet Points Stator generates rotating, sinusoidal B-Field: Introduction. Transformer . is the main reason to transmit and distribute power in AC. Transformer is a device which works on the principle of mutual induction. . Principle. . of operation. It is based on principle of . The transformer is a static device which is used to transfer electrical energy from one ac circuit to another ac circuit. . Input to a transformer and output from a transformer both are alternating quantities (AC).. PREPARED BY:. VRUNDA RANA (131130107049). KRIMA . PATEL . (131130107036). NIKITA THAKKAR (131130107061).
