LINEAR MOTOR FOR AIR VAPOR COMPRESSOR

This paper describes the modeling of linear motor compressor for use in household
refrigerator compressor system. Literature review has been conducted for various types of
linear motor technologies such as linear synchronous motor, linear induction motor, linear dc
motor and also linear permanent magnet motor. Three proposed designs has been proposed
which are tubular slotless linear motor using rectangular/trapezoidal permanent magnet with
the magnet arrangement separately with mild steel and tubular slotless linear motor with
rectangular permanent magnet. The designs are proposed due to force capability, simplicity
and cost-effectiveness. Type of permanent magnet also will be taken into consideration. The
characteristic and other element of the motor will be simulated using ANSYS software.
The results in terms of air gap flux density and moving force have been presented. The most
suitable design is chosen based on the higher average value of magnetic flux and force. In
addition, this project is mainly focused on the selection of the design from the three proposed
design that have been proposed. In future work, the selected design then can undergo design
optimization to prove that the design can increase the efficiency of the compressor and thus
reduce the power consumption.
