Tiivistelmä

The design process of direct-driven permanent
magnet synchronous machines (PMSMs) for a full electric 4 ´ 4
sports car is presented. The rotor structure of the machine
consists of two permanent magnet layers embedded inside the
rotor laminations thus resulting in some inverse saliency, where
the q-axis inductance is larger than the d-axis one. An integer slot
stator winding was selected to fully take advantage of the
additional reluctance torque. The performance characteristics of
the designed PMSMs were calculated by applying a twodimensional
finite element method. Cross-saturation between the
d- and q-axes was taken into account in the calculation of the
synchronous inductances. The calculation results are validated
by measurements.
