Demonstration of linear induction motor and Matrix converter
Greetings from Department of EEE, Jerusalem college of Engineering. We have installed linear induction motor lab set-up in our department. It was funded by AICTE-MODROB Scheme. A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. ... Their practical uses include magnetic levitation, linear propulsion, and linear actuators. About matrix converter: In industrial applications there is a strong demand for power quality and energy efficient power converters with reduced number of switches. MC has recently received considerable interests, because it possesses the necessary features to fulfil these current trends. The most desirable features of MC in power converters are a. Generation of output voltage with the desired amplitude and frequency b. Sinusoidal input current c. Sinusoidal output voltage d. Improved power factor e. Regeneration Capability These features of MC replace Voltage Source Inverters in IM drive applications. MC uses nine bi-directional controlled switches in a 3 x 3 matrix form to produce variable output voltage with variable frequency. The main advantage of MC is that it does not have any dc link and energy storing elements which reduce the performance of the converter
