Graphical Analysis for Performance of Electric motor of Compressor used in VCRS

In Vapour Compression Refrigeration System(VCRS), the electric motor used to run the compressor is called single phase induction motor. The control performance of compressor directly depends on the control parameters of single phase induction motor. In induction motor the temperature of auxiliary winding plays an important role to set the performance of motor. For example, when the temperature of auxiliary winding increases beyond a particular limit, the insulation of winding burns and hence the induction motor becomes short-circuited. To avoid this situation for a running compressor some accessories are attached in the circuit, which control this overheating effect by controlling the charge flow rate through the winding of induction motor. In this paper detailed prospects to avoid overheating or burning are suggested.
