    摘要: A method for assembling a motor shaft with a bearing, a motor housing, and an impeller is disclosed. A motor shaft extension is used to retain the impeller axially on the motor shaft and allows the motor shaft to drive an additional component, such as an impeller, located a distance from the motor. The motor shaft extension may be fabricated from aluminum or hardened steel. Additionally, the motor shaft extension may be embodied in a tube extending past the end of the motor shaft and a shaft extension pressed into the end of the tube.

    摘要: A vacuum cleaner capable of drawing different current levels in vacuum and blower modes is disclosed. The vacuum cleaner comprises at least one electric motor and an impeller disposed in an impeller housing, the impeller driven by the at least one electric motor. A receptacle has an inlet and an orifice in fluid communication with the impeller housing, wherein the impeller creates a low pressure area in the receptacle thereby drawing air into the inlet. An outlet is in air flow communication with the impeller housing, wherein air from the impeller is expelled through the outlet. A switch is associated with the outlet, wherein the switch has a first position in which a first current may be drawn by the at least one motor and a second position in which a second current, less than the first current, may be drawn by the at least one motor. A device is removably attached to the outlet for directing air.

    摘要: A support structure includes first and second support members which are interlocked with a body. The second support member is placed in a die such that a hole of the second support member is located at a predetermined position and the body is placed on the second support member. The first support member is placed on the body such that apertures of the support members and an opening of the body are aligned. A shaping pin is then advanced toward the first support member in alignment with the predetermined position so that a shoulder of the shaping pin extends into the first support member. The shaping pin continues to advance through the first support member until a portion of the body extends past a surface of the second support member, thereby joining the first and second support members and the body together.

    摘要: An electric motor brush subassembly includes a housing base, a housing cover, a brush, and a constant force spring. The brush is mounted between the housing base and the cover with the coil of the spring mounted adjacent to the outer end of the brush. The axis of the coil is disposed at a right angle with respect to the length of the brush and an unrolled spring segment extends along a side of the brush and is fixed in a slot in the cover. The spring exerts a force against the brush to bias the brush against the motor commutator.

    摘要: The disclosed mulcher has a base unit and a shredding blade in a removable assembly. Two different embodiments are disclosed. In both embodiments, shredded material is removed from air exiting the shredding blade before it reaches an exhaust port. In one embodiment, the material is removed by a filter. In the other embodiment, walls are arranged so that debris must double back against high-speed airflow leaving the shredding blade before exiting the unit. The shredding blade can be mounted in front of and on the same shaft as an air impeller, with the back surface of the shredding blade being supported by the impeller. In another embodiment, the air impeller and the shredding blade are carried in assemblies that are separable from each other and are each separately attachable to a base unit. A detachable power module and a detachable blower are also shown. The power module has a safety switch that disables the power module when it is removed. A power receptacle is shown with a switch that alternately switches power to either the shredder motor or to the power receptacle, but not to both simultaneously.

    摘要: A thermal protection mechanism for electric motors includes a pair of spaced contacts secured to an electrically insulating carrier having a cavity and a surface adjacent to a motor winding. The surface of the carrier has an aperture that forms a thermal passage between the surface of the carrier and the cavity. The contacts are engaged with a fusible electrically conductive pin made of solder that is disposed within the cavity and that interposes along a current path to the windings of a motor. A high winding temperature causes the pin to fuse, thereby terminating operation of the motor.
