Abstract: A permanent magnet shaft bearing includes a shaft bearing bushing and a flange bearing bushing which are magnetized to saturation. The outer surface of the shaft bearing bushing is magnetized to have the same polarity as the inner surface of the flange bearing bushing so that both bearing surfaces repel one another. Such repulsion creates a space between the bearing surfaces so that no physical contact is present. Both the flange bearing bushing and the shaft bearing bushing are tapered to mate each other. The shaft load requirements determine the magnetic flux density, the mass of the bearing bushings, the composition of the bearing bushings, and the proper angle of the taper. An insulating sleeve protects the bearing bushings from heat transfer in order to help retain permanent magnetization. A magnetically impermeable shield protects the bearing bushings from attracting metal particles.

Abstract: The present invention includes an electromagnetic motor having an asymmetric field stator. An aluminum rotor 6 includes a gorup 26 of permanent magnets that occupy a 153.degree. segment of the rotor 6 and are counterbalanced mechanically by brass counterweights 28 on the other side of the rotor 6. An aluminum stator housing 42 includes a large segment 48 of permanent magnets 54 separated by an electromagnet segment 50 from a small segment 52 of permanent magnets 54. The large segment 48 subtends an angle of 122.degree., the small segment 52 an angle of 22.degree.50' and the electromagnets 43.degree.. The permanent magnets 54 and electromagnets 56 and 58 of the staotr 42 produce a magnetic field that can have its center shifted from a first position or equator C by 32.degree.25' to a second position or second equator C'. As the rotor 6 spins the shifting of the center of the magnet field created by the stator 42 imparts momentum to the rotor 6 as it tries to align with the stator magnetic field.

Abstract: The present invention provides enhanced electromagnetic radiation transmission by providing an electrically conductive lamination between the silicon iron laminations in transformers, motors, alternators and solenoids. The conductive laminations increase the transmission of electromotive force and enhance cooling. An alternative to providing conductive laminations in a laminated core or stator is to provide a solid sintered metal core including iron, silicon and a conductor. Each transformer also includes a conductive amplifier coil connected in series with the primary coil and circling the primary coil and another conductive coil connected in series with the secondary coil and circling the secondary coil. The coils take advantage of the negative induction current described by Lenz's law to increase efficiency. In a motor, the stator laminations are optionally surrounded by a conductive amplifier coil which produces an amplification effect.

Abstract: An improved magnetic sensor assembly comprising a permanent magnet recessed within a pole extension magnet with a pick-up coil disposed around a portion of the pole extension magnet, each of the permanent and pole extension magnets having one end thereof substantially coplanar. The sensor assembly may be enclosed within a magnetic shield having an access opening providing access to the sensing region of the sensor assembly.

Abstract: A rotor and base, rotatingly connected, are each provided with a plurality of magnet assemblies. The magnet assemblies on one of the rotor and base are fixed and the magnet assemblies on the other of the rotor and base are moved radially in synchronization with the rotation of the rotor to produce a torque on the rotor.

Abstract: A magnetic coin element sensor for sensing, detecting and identifying coin elements and the like interposed in a magnetic field wherein the metallurgical structure of each interposed coin element causes an identifiable change in the magnetic field responsive to the metallurgical structure of the interposed coin element and uniquely indicative of the interposed coin element, the change in the magnetic field being sensed, detected and utilized to uniquely identify each of the interposed coin elements. The magnetic coin sensor is particularly useful for identifying coins deposited in a coin handling apparatus such as a vending machine, a coin telephone or the like.
