May 31, 2016· Construction of Linear Induction Motor: The stator is cut axially and spread out flat in Linear Induction Motor (LIM). In this type of motor, the stator and rotor are called primary and secondary respectively. The secondary of the linear induction motor consists of a flat Aluminium conductor with a ferromagnetic core.
They are, fundamentally, rotary motors that are rolled out flat. In a linear motor, the rotor rolled out to become a magnet track. The rotary stator became linear motor forcer coil assembly. It is typical, in linear applications, for magnet track to be stationary and to have a moving forcer assembly, due to their relative sizes and masses.

Electric motor - Electric motor - Construction of induction motors: The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.
The trainsets themselves are popularly known in Japan as linear motor car (リニアモーターカー, rinia mōtā kā), though there have been many technical variations. Government permission to proceed with construction was granted on May 27, 2011. Construction of the line, which is expected to cost over ¥9 trillion, commenced in 2014.
Jun 28, 2017· Synchronous speed of linear motor can represent by following equation. Ns =2fs/p. fs = supply frequency (Hz) P = number of poles in motor. Ns = synchronous speed of the motor. What is Double Sided Linear Induction Motors . In double sided linear induction motor (DLIM) there are primary on both side of the rotor side.
A Linear Induction Motor (LIM) is a specific type of alternating current (AC), multiple-phase machine that provides force and movement in a linear direction. Numerous applications of LIM's can be found in industry today, one of the most interesting being high speed magnetic levitation railway systems.
Related Post: Servo Motor – Types, Construction, Working, & Applications What is a Stepper Motor? Stepper Motor is a brushless electromechanical device which converts the train of electric pulses applied at their excitation windings into precisely defined step-by-step mechanical shaft rotation. The shaft of the motor rotates through a fixed angle for each discrete pulse.
