Abstract

A new wall-mountable vacuum cleaner and bracket combination provides easy locking. Both the vacuum cleaner and the bracket have mounting rims. When the vacuum cleaner is on the bracket, a support surface on a proximal end of one of the two mounting rims engages a terminal edge of the other of the two mounting rims. The vacuum cleaner can be secured in place by moving a movable arm from an extended position to a retracted position in which the vacuum cleaner is locked in place. To accommodate the required movement of the movable arm, the bracket has a deflectable locking edge that moves between a rest position and a deflected position. In the rest position, the distance between the locking edge and the terminal edge of the bracket mounting rim exceeds the distance between the terminal edge of the vacuum mounting rim and the base surface, but is less than the distance from the terminal edge of the vacuum mounting rim to the part of the vacuum cleaner that lies directly beneath the locking edge when the vacuum cleaner is stored on the bracket.

Abstract

In a method of controlling current in a control circuit of an electric motor, pulse-width modulation (PWM) pulses are applied to a stator of the electric motor, via a plurality of transistors of the control circuit, using a first control mode when a rotational speed of a rotor of the electric motor is within a first range. At least one PWM pulse is applied to the stator, via a subset of the plurality of transistors, using a second control mode when the rotational speed of the rotor is within a second range. When it is determined that the rotational speed of the rotor has changed from being within the second range to being within the first range, additional PWM pulses are applied to the stator such that, for each of the plurality of transistors, a current through the transistor does not exceed a maximum current capacity of the transistor.

Abstract

Methods and systems of accelerating a brushless, DC electric motor based on torque may include determining a slope based on a maximum torque of the BLDC motor at a lower operating load and a maximum torque of the motor at a higher operating load, determining a period of the rotor based on sensor signals, and determining and applying a phase advance to a PWM pulse for a subsequent revolution of the rotor based on the period and the slope. In some embodiments, the amount of the phase advance is further based on maximum load optimum advance and/or maximum load speed. In some embodiments, a phase dwell is determined based on a positive torque zone and applied to the PWM pulse. In some embodiments, when the motor is operating below a given threshold, fixed-width PWM pulses are applied to subsequent revolutions of the rotor instead of phase-advanced PWM pulses.

Abstract

A new motor assembly uses a switch module to facilitate the assembly of an electric motor. The switch module can be prefabricated, and is connected to a terminal block on the motor by plug and socket connectors on the terminal block and on a terminal end of the module. The switch module is pre-wired with a power inlet and a switch, eliminating the need for a worker on the motor assembly line to make difficult electrical connections to a traditional terminal block. The switch is arranged in a switch housing that fits within an extension on the motor housing. An interior support wall on the housing fits within a channel between the switch housing and the rest of the switch module, helping to hold the assembly in position. The power inlet is positioned laterally outward from the terminal end and laterally inward of the switch.

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.

Abstract

The disclosed vacuum cleaner system for an automobile fits in a cavity in the vehicle and has a tank that can be removed in a lateral direction without tools and without detaching the vacuum hose. A circuit board that carries an electronic controller is positioned alongside the motor and extends generally parallel to both the axis of the motor and the lateral direction in which the tank is removed. Cooling air is drawn though a cooling air inlet on the cabin wall to the circuit board, and then one side of the motor, through the center of the motor, to the cooling fan. From there, it is blown into a cavity where it joins exhausted working air from the vacuum and is exhausted from the vehicle through an air release opening that leads to the exterior of the vehicle.
