To improve the control performance of an automotive traction drive, this work proposes a direct flux sensing concept: An array of six high-resolution flux sensors is integrated into a traction motor. One PCB with the flux sensors is placed between stator laminations and end windings of an electrically excited synchronous motor (EESM) for BEV traction applications. The Integrated Flux Sensor Array (ISA) offers several advantages: it provides more sensor information from 18 flux measurements (+ temperature), has no moving parts, requires less space, and reduces costs by more than 80% compared to a mechanical resolver. Flux is measured with low distortion through low order cancellation applying spatial multipath sampling. HV-testbench measurements demonstrate closed-loop control using the ISA concept replacing the resolver also at low speeds.
