It is crucial to use an efficient motor in an HVAC system as the majority of the power is consumed by the compressor motor. Although the permanent magnet synchronous motor has been a viable solution with high efficiency, the induction motor is the dominant type in the industry primarily due to the cost of rare earth magnets. As an alternate solution, non-rare-earth permanent magnet assisted synchronous reluctance motors have been studied in depth. In this thesis, analytical models of permanent magnet assisted synchronous reluctance machines are discussed. Based on the analytical models, design variables are selected such that, while meeting the mechanical constraints, the difference between d-axis magnetizing inductance and q-axis magnetizing inductance is maximized. Additionally, using finite element analysis the design is optimized specifically for compressor application, maximizing integrated part load value efficiency. As a result, efficiency of 97.28% (IPLV of 96.65%) at rated speed of 16500 rpm is achieved. The design is also compared with a standard-general purpose induction machine and permanent magnet synchronous motor in terms of cost and efficiency.","abstract_html":"A large portion of electricity is consumed in HVAC systems of residential and commercial sectors.
