“…Tolerance analysis is performed on a 24-slot 28-pole TCW-MPMSM, considering the design parameters shown in Table 1, and results that were presented in a previous conference publication [10]: a tooth-tip width of 6 mm and pole-to-arc ratio of 0.9 should be adopted in the machine. These Given the novelty of TCW-MPMSM, clear tolerance values for their manufacturing do not exist so far.…”

“…where d is an integer equal to Q s /6 [7]. In this section, a 24-slot 28-pole outer-rotor machine is analyzed, which was previously optimized with focus on the full-load electromagnetic torque mean value [10]. Tooth tips are included to increase the flux linkage and, consequently, to enlarge the back electromotive force (back-EMF) and the electromagnetic torque.…”

“…Depending on the geometry, the modular stator structure can be classified as either an I-shape [9], E-shape, or U-shape [10] (also called a C-shape). The I-shape stator core is commonly used in yokeless and segmented armature (YASA) axial flux permanent magnet machines [9], whereas the E-shape and the U-shape structures are typically adopted in radial flux topologies.…”

This paper analyzes the impact of manufacturing tolerances on the cogging torque of a 24-slot 28-pole tooth-coil-winding permanent magnet synchronous machine with a modular stator core (TCW-MPMSM). Dimensional tolerances and asymmetries associated with the modular topology are studied by means of finite element simulations in order to identify key parameters that increase the cogging torque above the expected values of a faultless machine. Among five selected dimensional parameters, it was found that angular displacement, radial displacement, and tooth–tip width deviations of the stator segments have the most significant impact on the cogging torque. Considering these three key parameters, a full-range tolerance analysis is carried out by means of a proposed superposition-based approach, evaluating all possible combinations of typical deviation values. It is concluded that the cogging torque increment, generated by tolerances, is relatively independent of the faultless tooth–tip width of the stator segments and the arc-to-pole ratio. Robustness of the TCW-MPMSM, regarding cogging torque generation, depends on both the tightness of the tolerances handled in the manufacturing process and the rated cogging torque: the lower the cogging torque of the ideal machine, the less robust is the machine and, therefore, manufacturing imperfections will be required to be tightened.
