  • Patent number: 8429792
    Abstract: A cleaning appliance includes a motor arranged to drive a fan for generating suction air flow and a cleaner head having a drivable agitator with a dedicated motor. The agitator drive motor has a selectively-operable switch and a resettable circuit breaker arranged such that, when the switch is activated, the circuit breaker is reset. A button actuates the switch and simultaneously resets the circuit breaker. When there is a blockage so that the circuit breaker trips out the motor, the user can reset the circuit breaker and restart the agitator motor by the simple act of depressing one button, thereby obviating the need for a separate control.

  • Patent number: 8312590
    Abstract: Embodiments of a switched reluctance (SR) motor for use in a integrated vacuum system for a vehicle are disclosed. The SR motor may receive input voltage directly from an electrical storage device used to start up an engine of the vehicle. The SR motor may include an encoder that triggers an optical sensor to provide signals to a motor controller. The motor controller may energize stator poles based on the received signals. The encoder may be mechanically phase-advanced with respect to poles of the rotor to ensure proper start-up of the SR motor. Commutations of the motor may occur before a point of maximum inductance where the rotor and stator are aligned. In a preferred embodiment, the input voltage received by the SR motor is in a range of 9-16 Volts DC, a maximum drawn current is 36 amps, and the phase advance is between 9-11 degrees.

  • Publication number: 20120279011
    Abstract: A vacuum cleaner with a cooled drive belt is described. The vacuum has a handle, body, base housing, cooling fan, motor, drive belt and a drive belt housing. A fan draws ambient air over a drive belt within the belt housing. The belt housing can have a main belt housing and a belt housing cover. The belt housing can contain an air intake and air exhaust connected by an air duct. Belt housing can have a filter in order to clean intake air. The result is a vacuum with significantly greater longevity—reducing costs and increasing reliability of the vacuum for the user.
