Linear Induction Motor Diagram
They are capable of speeds up to 1800 insec 45 ms and are typically used in applications where accurate positioning is not required.
Linear induction motor diagram. The voltage and current is induced in the rotor circuit from the stator circuit for the operation. 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. Characteristically a linear motors active section has ends whereas more conventional motors are arranged as a continuous loop. In this type of motor the stator and rotor are called primary and secondary respectively.
Linear induction motor a linear induction motor lim is an advanced version of rotary induction motor which gives a linear translational motion instead of the rotational motion. Linear induction motor background alternating current ac electric motor powered by a three phase voltage scheme force and motion are produced by a linearly moving magnetic field used in industry for linear motion and to turn large diameter wheels 6 4. Equivalent circuit of an induction motor enables the performance characteristics which are evaluated for steady state conditions. Linear induction motor design.
Linear induction motors have also been used for launching aircraft the westinghouse electropult system in 1945 was an early example and the electromagnetic aircraft launch system emals was due to be delivered in 2010. Force engineering is a company with a truly global scope dedicated to the development design and production of linear induction motors and other electro magnetic and permanent magnet solutions. Save shaded pole motor is a split phase type single phase induction motor. Numerous applications of lims can be found in industry today one of the most interesting being high speed magnetic levitation railway systems.
However linear motors are not necessarily straight. The equivalent circuit of an. Save save it has salient poles on the stator excited by single phase supply and a squirrel cage rotor. A linear induction motor lim is a non contacting high speed linear motor that operates on the same principal as a rotary squirrel cage induction motor.
The stator is cut axially and spread out flat. 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. An induction motor is based on the principle of induction of voltages and currents.
