History. The history of linear electric motors can be traced back at least as far as the 1840s to the work of Charles Wheatstone at King''s College in London, but Wheatstone''s model was too inefficient to be practical. A feasible linear induction motor is described in US patent 782312 (1905 inventor Alfred Zehden of FrankfurtamMain), and is for driving trains or lifts.
Ultrasonic Motor Working The vibration is induced into the stator of the motor, and it is used for conveying the motion to the rotor and also to modulate the frictional forces. The amplifiion and (micro) deformations of active material are utilized for generation of the mechanical motion.
A linear motor is an electric motor that has had its stator and rotor "unrolled" thus instead of producing a torque it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor''s active section has ends, whereas more conventional motors are arranged as a continuous loop.
How Does a Linear Induction Motor Work? Linear induction motor (LIM) theory is most easily understood as a rotary motor that has been cut and unrolled to generate linear motion, instead of rotary motion. It is comprised of two parts, the primary and secondary, which interact with one another only when power is applied.

This article outlines basic construction and working of a DC generator. Construction of a DC machine: Note: A DC generator can be used as a DC motor without any constructional changes and vice versa is also possible. Thus, a DC generator or a DC motor can be broadly termed as a DC machine.
Just like a DC Machine, a same induction machine can be used as an induction motor as well as an induction generator, without any internal modifiions duction generators are also called as asynchronous generators. Before starting to explain how an induction (asynchronous) generator works, I assume that you know the working principle of an induction motor.
