Patent number: 9246362Abstract: A stator is formed from two stacks of laminations have different outer perimeters to enable electrical motors with different output ratings to be built with a same hub-to-hub distance. The stator includes a first plurality of laminations having a first outer perimeter with at least two flanges with mounting holes, and a second plurality of laminations having a second outer perimeter that is different than the first outer perimeter. The second outer perimeter of the laminations in the second plurality of laminations are configured to enable a portion of an endplate to pass the second plurality of laminations and contact a face of the first plurality of laminations.Type: GrantFiled: March 14, 2013Date of Patent: January 26, 2016Assignee: Nidec Motor CorporationInventors: Marshall J. Huggins, Stephen J. Burton

Patent number: 9228292Abstract: A drying device has been developed having a single electric motor configured to drive a drum and directly drive an air blower. The single electric motor is a non-line frequency electric motor. The drum is coupled to a support frame to enable rotation of the drum relative the support frame. The drum has an interior space for holding a load of articles, such as clothing. The motor includes a controller configured to regulate the angular velocity of the output shaft of the motor with reference to the current drawn by the motor.Type: GrantFiled: December 20, 2013Date of Patent: January 5, 2016Assignee: Nidec Motor CorporationInventors: Robert E. Wehrheim, Keith I. Hoemann, Gregory A. Peterson, L. Ranney Dohogne, Marshall J. Huggins, Gregory M. Levine

Patent number: 8615897Abstract: A drying device has been developed having a single electric motor configured to drive a drum and directly drive an air blower. The single electric motor is a non-line frequency electric motor. The drum is coupled to a support frame to enable rotation of the drum relative the support frame. The drum has an interior space for holding a load of articles, such as clothing. The motor includes a controller configured to increase gradually the angular velocity of the drum to provide a “soft start” for the dryer.Type: GrantFiled: July 16, 2009Date of Patent: December 31, 2013Assignee: Nidec Motor CorporationInventors: Robert E. Wehrheim, Keith I. Hoemann, Gregory A. Peterson, L. Ranney Dohogne, Marshall J. Huggins, Gregory M. Levine

Publication number: 20100031529Abstract: A clothes dryer includes a motor adapted to be mounted on a frame of the dryer for driving a dryer belt to rotate a drum of the dryer. The motor includes a rotor adapted to rotate the belt, at least one winding energizable to cause rotation of the rotor, and a first switch operable to control energization of the winding. A second switch has a sensor for sensing belt breakage. The second switch is mounted on the first switch and is electrically connected to the winding so that when the belt is no longer sensed, the second switch stops operation of the winding and thereby stops rotation of the rotor.Type: ApplicationFiled: October 14, 2009Publication date: February 11, 2010Applicants: Emerson Electric Co., BSH Home Appliances CorporationInventors: Philip S. Johnson, Marshall J. Huggins, Michael Peebles, John R. Holden

Patent number: 5877572Abstract: A reluctance machine system is provided that comprises a reluctance machine having a stator defining a plurality of stator poles, a plurality of phase windings wound around the stator poles, and a rotor defining rotor poles and inter-pole gaps. Contoured topsticks, a dust cover and an endshields are used to reduce the amount of noise in the reluctance system. A winged terminal housing is also used to allow manipulation of the terminal housing and enhance alignment while protecting critical wires.Type: GrantFiled: October 1, 1996Date of Patent: March 2, 1999Assignee: Emerson Electric Co.Inventors: Paul G. Michaels, Barry M. Newberg, Marshall J. Huggins, Vernon E. Kieffer
