Optimal Pole Number and Winding Designs for Low Speed–High Torque Synchronous Reluctance Machines

Abstract: This paper studies the feasibility of using synchronous reluctance machines (SynRM) for low speed-high torque applications. The challenge lies in obtaining low torque ripple values, high power factor, and, especially, high torque density values, comparable to those of permanent magnet synchronous machines (PMSMs), but without resorting to use permanent magnets. A design and calculation procedure based on multistatic finite element analysis is developed and experimentally validated via a 200 Nm, 160 rpm prototy… Show more

“…The rotor of the reference SynRM was optimized with its stator in [22] to obtain an improved performance. A rotor with 4-poles is selected as it has been proved in [24] that a 4-poles rotor shows a better performance. Consequently, 20, 40 and 60 slots are the possible number of slots of the 5-phase stator which achieve the constrains of (2) and Table I.…”

“…However, unfortunately, a simple and balanced 5phase winding might not be possible from the existing 3phase stator. This is because, most of the existing 3-phase stators were manufactured to give an integer number of slots per pole per phase with 3-phase winding (18,24,36 or 48slots and 2, 4 or 6-poles) [15]. Consequently, a fractional number of slots per pole per phase will be obtained when applying a 5-phase winding to these stators.…”

“…By use of some optimal design methods, 1,2 the synchronous reluctance motors (SynRMs) have high power factor, high efficiency and low torque ripple compared with the induction motors (IMs). The SynRMs have been diffusely applied in the moving fluids and the textile industry, such as water well pumps and fiber spinning machines.…”

“…Low-speed permanent magnet (PM) machines have attracted increasing attention in several fields, such as wind power generation, electric vehicles, electric vessels, home appliances, etc. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. They can offer so-called direct-drive operation, which is beneficial for avoiding disturbances caused by a gearbox [7].…”
