Abstract: A method and apparatus for quasi-sensorless adaptive control of a high rotor pole switched-reluctance motor (HRSRM). The method comprises the steps of: applying a voltage pulse to an inactive phase winding and measuring current response in each inactive winding. Motor index pulses are used for speed calculation and to establish a time base. Slope of the current is continuously monitored which allows the shaft speed to be updated multiple times and to track any change in speed and fix the dwell angle based on the shaft speed. The apparatus for quasi-sensorless control of a high rotor pole switched-reluctance motor (HRSRM) comprises a switched-reluctance motor having a stator and a rotor, a three-phase inverter controlled by a processor connected to the switched-reluctance motor, a load and a converter.

Abstract: The present embodiment is a high rotor pole switched reluctance machine (HRSRM) which provides a plurality of combinations of the number of rotor poles Rn and number of stator poles Sn utilizing a numerical relationship defined by a mathematical formula, Rn=2Sn?Fp, when Sn=m×Fp, wherein Fp is the maximum number of independent flux paths in the stator when stator and rotor poles are fully aligned, and m is the number of phases. The mathematical formulation provides an improved noise performance and design flexibility to the machine. The mathematical formulation further provides a specific number of stator and rotor poles for a chosen m and Fp. The HRSRM can be designed with varying number of phases. The HRSRM provides a smoother torque profile due to a high number of strokes per revolution.

Abstract: A system and method, in various embodiments, maintains a cryptographically protected ledger of transactions pertaining to enabling a property owner to require subsequent holders of interests in its property to verify the property owner's informed consent to any transaction that creates or created an interest in its property in any other party. The method may include receiving, at a computing device running an automated agent, a request from a property owner to prepare a record of a contract for verifying and authenticating title-modifying transactions according to a protective scheme included in the contract and a covenant recorded against the title of the real property, which are stored as digital records in a cryptographically protected ledger. A digital certificate is used to verify authenticity of the digital records and confirm consent to the title-modifying transaction.
