Abstract:
A device such as an electric motor, an electric generator, or a regenerative electric motor includes at least one stator arrangement having a plurality of electromagnetic assemblies with each electromagnetic assembly including at least a portion of a magnetic core that is formed from thin film soft magnetic material. The electromagnetic assemblies define a plurality of stator poles. The device also includes at least one rotor arrangement supported for rotation about a given rotational axis at a certain range of normal operating rotational speeds. The rotor arrangement has a plurality of rotor poles for magnetically interacting with the stator poles. The rotor poles are supported for rotation about the rotational axis along a circular path. A switching arrangement for controlling the electromagnetic assemblies is configured such that the switching arrangement is able to cause the stator poles of the electromagnetic assemblies to magnetically interact with the rotor poles of the rotor arrangement within a certain range of frequencies. The number of rotor poles is selected to be a number such that the switching arrangement causes the stator poles of the electromagnetic assemblies to magnetically interact with the rotor poles of the rotor arrangement in a way which causes the ratio of the frequency of the device in cycles per second relative to the revolutions per minute of the device to be greater than 1 to 4 during the operation of the device.
Abstract:
A device such as an electric motor, an electric generator, or a regenerative electric motor includes a rotor arrangement and a stator arrangement. The stator arrangement has a dielectric electromagnet housing and at least one energizable electromagnet assembly including an overall amorphous metal magnetic core. The overall amorphous metal magnetic core is made up of a plurality of individually formed amorphous metal core pieces. The dielectric electromagnet housing has core piece openings formed into the electromagnet housing for holding the individually formed amorphous metal core pieces in positions adjacent to one another so as to form the overall amorphous metal magnetic core. The device further includes a control arrangement that is able to variably control the activation and deactivation of the electromagnet using any combination of a plurality of activation and deactivation parameters in order to control the speed, efficiency, torque, and power of the device.

Abstract:
A reel includes a reel drum enclosed within a housing comprising a first housing portion, a second housing portion, and a middle housing portion positioned therebetween. A spindle member has a first end connected to the first housing portion and a second end connected to the second housing portion. The spindle member extends through an opening in the drum so that the drum is rotatable about a spindle axis defined by the spindle member. The middle housing portion encircles the drum and has an aperture through which linear material can extend, the linear material of a type that may be spooled on the drum. The middle housing portion is rotatable about the spindle axis independently of the drum. In preferred embodiments, the reel is a cord reel and the linear material is electrical cord. In preferred embodiments, the middle housing portion is rotatable at least 360° about the spindle axis. In preferred embodiments, the drum is powered by an electric motor. In preferred embodiments, the housing is substantially spherical and the reel further comprises one or more support structures that include handles and are configured to prevent the housing from contacting a flat surface such as a floor or wall. In preferred embodiments, one or more temperature-sensitive switches are configured to shut off power to a spooled electrical cord in the event that a temperature of the reel exceeds a given threshold. In preferred embodiments, a solenoid is provided for locking the middle housing portion with respect to the first and second housing portions while the motor is rotating in a direction to spool the linear material onto the drum.
Abstract:
A hose control system comprising a receiver and a transmitter by which one can remotely control both the flow of water through a hose and the winding or unwinding of the hose onto a reel. The system preferably has power saving advantages, for example, by the use of a power control unit that reduces the power consumed by the electronics of the devices, but does not unreasonably disrupt the use of the devices. The receiver may be used with different aspects or all of the hose control system.
