A novel winding configuration for an open-slot permanent magnet synchronous machines with modular stator (MPMSM) that improves the electromagnetic performance is proposed in this paper. Core-coil-winding (CCW) in combination with tooth tips between the stator modules are used to increase the induced voltage and electromagnetic torque. Furthermore, the proposed topology helps to reduce the eddy current losses in the permanent magnets. A 24 slot and 20 poles CCW-MPMSM is analyzed by means of finite element method and compared with a machine with the same rotor structure and continuous stator core (classical topology). The preliminary results show that the CCWMPMSM achieves similar performance compared to the classical topology when a suitable value of tooth tips width is selected.
