Theory of linear induction motor
WebbThe use of linear machines for industrial purposes is described and this is followed by a report of their application to transport propulsion and levitation. The development of linear forms of induction motor, synchronous motor, stepper motors, DC motors, permanent magnet motors and reluctance motors is described. Webb17 dec. 2024 · Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. In a traditional electric motor , the rotor (rotating part) spins inside the stator (static …

WebbEquation 1. In the supply-frequency equivalent circuit, the secondary e.m.f. is E 2, rather than sE 2, so to obtain the same current in this model as given by equation (1), we require the slip-frequency rotor resistance and reactance to be divided by s, in which case the secondary current would be correctly given by. WebbInduction motors are most commonly run on single-phase or three-phase power, but two-phase motors exist; in theory, induction motors can have any number of phases. Many single-phase motors having two windings …
