Abstract: A system and method including a runtime thermal model that estimates individual component temperatures, permitting the system to only limit power when necessary or desirable. A power-limiting system for a vector-controlled AC induction motor includes a torque command system for generating a torque command; a thermal protection system determining a runtime estimate for a temperature of a component of a rotational electro-magnetic component of the vector-controlled AC induction motor; and a controller configured to generate a motor control signal for the vector-controlled AC induction motor responsive to the torque command, wherein the thermal protection system determines the runtime estimate responsive to a multi-node thermal model of the vector-controlled AC induction motor, and wherein the controller limits a power of the vector-controlled AC induction motor to maintain a component temperature below its critical temperature.

Abstract: A method of manufacturing a three-phase, four pole motor is provided utilizing a dual-layer winding insertion technique. The first and second winding layers are each comprised of the coil groups for six individual poles, two per phase. Within each layer, the two poles per phase are members of a pole pair. In one configuration, each winding layer is comprised of six concentric coil groups in which there is no coil overlap; alternately, each coil group may be comprised of five coils with either the first or second or both outermost coils of each group being double-turn coils; alternately, each coil group may be comprised of five coils with no coil doubling, although there are overlapping coils from different coil groups; alternately, each coil group may be comprised of five coils with no coil doubling and no overlap between different coil groups, although the coils within each coil group are completely lap wound.
