摘要： The disclosed vacuum assembly can be mounted in a vehicle. The motor/fan assembly is positioned above a chassis wall. Lateral flanges on opposed sides of the tank support the tank in generally horizontal sliding motion from a forward position to an elevated rearward position. A rear flange supports the tank as it pivots to a mounted position in which an inlet on a removable lid on the tank communicates with a hose, and an outlet on the lid communicates with the motor/fan assembly. In a removed position, the inlet and outlet are disconnected. Alignment bosses fit in aligned openings when the tank is in the mounted position.

摘要： In a method of controlling speed of a brushless, direct current (BLDC) motor based on dwell, an indication of a desired speed of the BLDC motor is received. A dwell is determined based on a magnitude of a voltage corresponding to the indication of the desired speed. A pulse-width modulation (PWM) pulse having a pulse length corresponding to the determined dwell is applied to a stator of the BLDC motor to adjust a rotational speed of a rotor of the BLDC motor to the desired speed.

摘要： 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.

摘要： 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.

摘要： A control circuit for a motor includes a voltage regulator having a thermal shutdown apparatus that turns off the voltage regulator when the temperature of the control circuit rises above a pre-determined threshold level, wherein the voltage regulator is used to provide power to a plurality of insulated gate bipolar transistors controlling a plurality of stator windings of the motor. Thus the voltage regulator prevents the control circuit and the various components on the control circuit from being damaged from overheating. An embodiment of the control circuit is adapted to generate an error code in response to the shutdown of the voltage regulator and to monitor the operation of the motor to ensure that the motor has been turned off and then on before turning on the power supply to a plurality of phase windings.

摘要： A new vacuum cleaner that is adapted for use in a vehicle has a user-removable debris collection tank that has spaced recesses on the bottom that inhibit both fore-and-back movement of debris within the collection tank and side-to-side movement of debris within the collection tank. The recesses are located in opposed outer corners of the tank, and have lower surfaces that support the tank in a standing position. Raised sections divide each of the recesses into two corner recess sections and an offset recess section, and inhibit both fore-and-aft movement of debris within the recesses and side-to-side movement of debris within the recess sections. The offset recess section has tracks that curve in different directions from an intermediate position adjacent or near a side of the tank. The bottom of the tank is generally curved downwardly towards the sides of the tank.
