Abstract: One or more examples relate, generally, to an orientation of a rotor. Some examples relate to an apparatus. The apparatus may include sample-accumulation logic to generate, over a time duration, a value indicative of inductance at least partially responsive to a probe signal provided to a stator of a motor. The apparatus may also include a probe-current discriminator to generate a further value indicative of an orientation of a rotor of the motor at least partially responsive to the generated value. The apparatus may also include update logic to update a process variable of a control loop at least partially responsive to a state of the further value.
