A Cost-Effective Switched Reluctance Motor Drive for Vacuum Cleaners

A cost-effective switched reluctance motor drive for vacuum cleaners is presented in this work, as good compromise between performance and costs. Low resolution rotor position sensors are utilized in the proposed motor drive in combination with a vector tracking observer, providing an accurate control of the turn-on and turn-off angles of each motor phase, and a high bandwidth speed estimation. Effectiveness of the technical solution has been verified by experimental tests performed on a 300W switched reluctance motor drive.
