April 16, 2026
Examples described herein provide a vehicle that includes a drive unit. The drive unit includes a printed circuit board (PCB) having a coil assembly. The drive unit further includes a rotor assembly connected to a shaft, the shaft having a target. The drive unit further includes circuitry electrically coupled to the coil assembly, the circuitry transmitting an electromagnetic field from the coil assembly to the target on the shaft, receiving a reflected electromagnetic field at the coil assembly from the target on the shaft, and determining a position of the shaft based at least in part on the reflected electromagnetic field.
