Abstract:
Implementations of a system for sensing rotor position of a PMSM may include: a controller which may be coupled with the PMSM. The controller may be configured to apply a plurality of voltage vectors to the PMSM to generate a plurality of sensing signals from a stator of the PMSM in response. A comparator may be coupled to the PMSM configured to receive and to compare each one of the plurality of sensing signals with a threshold voltage. A rise time measurement circuit may calculate a plurality of rise times using the plurality of sensing signals in response to receiving a signal from the comparator. The rotor-angle estimation circuit may be configured to identify from the plurality of rise times a shortest rise time and a voltage vector corresponding with the shortest rise time and thereby identify the position of the rotor of the PMSM.

Claim (Index 18):
The method of  claim 17 , further comprising generating a first threshold current and a second threshold current using the controller, wherein the first threshold current and the second threshold current are related by the equation I th \ue89e \ue89e 1 = 4 3 \ue89e I th \ue89e \ue89e 2 where I th1  is the first threshold current and I th2  is the second threshold current.
