Publication number: 20110285254Abstract: A self-starting electromotor having a stator and a rotor, the stator including at least one stator module of N toroid shaped electromagnets, the electromagnets arranged along an arc a predetermined distance apart defining a stator arc length. Each of the electromagnets has at least one gap. The rotor includes a disc adapted to pass through the at least one gap. The disc includes a plurality of permanent magnets spaced side by side about a periphery thereof and arranged so as to have alternating north-south polarities. The permanent magnets are sized and spaced such that within the stator arc length the ratio of permanent magnets to electromagnets is N+1 to N, to where N is the number of electrical excitation phases applied to the electromagnets.Type: ApplicationFiled: January 3, 2011Publication date: November 24, 2011Applicant: APEX DRIVE LABORATORIES, INC.Inventors: John E. Bales, Edward Failing Ritz, JR., Tommy Long, J. Lynn Saunders, Mohamed Sabri

Patent number: 6930433Abstract: An electromotive machine having a stator element and a rotor element, the stator element including at least one set of N preferably toroidally shaped electromagnetic members, the electromagnetic members arranged along an arc a predetermined distance apart defining a stator arc length. Each of the members has a slot, and the rotor element includes a disc adapted to pass through the slots. The disc contains a plurality of permanent magnet members spaced side by side about a periphery thereof and arranged so as to have alternating north-south polarities. These permanent magnet members are sized and spaced such that within the stator arc length the ratio of stator members to permanent magnet members is N to N+1, where N is the number of electrical excitation phases applied to the electromagnets. The electromagnetic members are energized to create high torque and smooth operation.Type: GrantFiled: August 4, 2003Date of Patent: August 16, 2005Assignee: Apex Drives Laboratories, Inc.Inventors: John E.
