Patent number: 10816013Abstract: An appliance provides a platform having a platform bottom and a platform base which supports a main base. A motor is carried by the platform base and rotates a ventilation fan which has a plurality of radial vanes with a fan aperture centrally positioned therein, such that the ventilation fan draws air in through an intake port provided by the platform. A fan shroud encloses the ventilation fan and has a shroud opening. The fan shroud extends from the platform base toward the platform bottom, wherein the main base surrounds the motor. The main base has an outer housing with at least one housing port, wherein rotation of the ventilation fan draws air into the fan aperture from the intake port, through the shroud opening, and expels the air radially from the plurality of radial vanes so that the air flows through the motor and out the housing port.Type: GrantFiled: January 22, 2019Date of Patent: October 27, 2020Assignee: AMETEK, INC.Inventors: Michael L. Gilliland, Robert A. Ciccarelli, Jr., David B. Finkenbinder

Patent number: 10221865Abstract: An appliance includes a reverse air flow motor housing. A casing carries and supports a motor, and a ventilation fan is rotated by a rotatable shaft driven by the motor. A lower platform with an air intake port carries a ventilation shroud that partially encloses the ventilation fan. An inner support is mounted between the lower platform and the casing. An outer housing has a sidewall that substantially encloses the motor and is supported by the lower platform. Rotation of the ventilation fan draws in ambient air through the air intake port which then proceeds between the casing and the motor and subsequently through the sidewall port.Type: GrantFiled: May 27, 2016Date of Patent: March 5, 2019Assignee: AMETEK, INC.Inventors: Michael L.

Publication number: 20070296293Abstract: A motor assembly having improved flux properties comprises a rotor lamination rotatably disposed within a field lamination. The field lamination comprises a constant cross-sectional dimension, and is configured to provide a pair of opposed, tapered yokes that provide constant impedance to the rotor lamination. The rotor lamination includes a plurality of spaced teeth that are dimensioned so that taper of the yokes changes by a factor of the width of one of the teeth, thereby reducing the material needed to adequately carry the magnetic flux of the rotor lamination.Type: ApplicationFiled: June 26, 2006Publication date: December 27, 2007Inventors: David B. Finkenbinder, Michael L. Gilliland

Patent number: 7091635Abstract: A flywheel/motor assembly is disclosed that comprises a motor housing having a sidewall and an end wall extending substantially perpendicularly from the sidewall. The end wall enclose a motor assembly having a rotatable shaft extending therefrom. The motor housing has at least one air flow opening therethrough. A flywheel is coupled to the shaft, and includes a pulley side and a motor side opposite the pulley side, wherein the motor side is aligned substantially with the end wall and does not extend over the sidewall. A plurality of vanes are associated with the flywheel, wherein adjacent vanes form channels therebetween. A ring is coupled to the plurality of vanes and at least partially encloses the channels and forms exhaust ports away from the shaft. Rotation of the flywheel draws air through the motor housing's openings into the channels and out the exhaust ports. The pulley side may include balancing bores for receiving balancing material to balance the finished assembly.Type: GrantFiled: October 20, 2004Date of Patent: August 15, 2006Assignee: Ametek, Inc.Inventors: Michael L Gilliland, David B Finkenbinder, Michael Coles

Patent number: 6762531Abstract: A motor assembly having improved flux density includes a field assembly and an armature assembly rotatably received by the field assembly. The field assembly includes a plurality of like laminations stacked upon each other wherein each field lamination comprises a pair of substantially parallel bracket sides, and a pair of substantially parallel yoke sides which are substantially perpendicular to the pair of bracket sides. Corner pieces connect the yoke sides to the bracket sides wherein the corner pieces are angularly directed between about 40° to about 50° with respect to the yoke sides and the bracket sides. A yoke extends inwardly from each yoke side to form an armature opening therebetween for rotatably receiving the armature assembly.Type: GrantFiled: October 25, 2002Date of Patent: July 13, 2004Assignee: Ametek, Inc.Inventors: Michael L. Gilliland, Robert K. Salamon, John M. Lebo

Patent number: 6309180Abstract: A molded through-flow motor assembly has a motor housing, including a cup portion and a flange portion. The flange portion includes a plurality of ramp surfaces extending outwardly therefrom. The cup portion has a field retaining wall and guide rib extending inwardly therefrom on opposite sides of the housing. A diffuser plate is provided having a plurality of scalloped ramp surfaces on a first side thereof adjacent to a plurality of air inlet apertures which open into air chambers on the second side thereof. The field and armature portions of a motor assembly are mounted in the motor housing and the diffuser plate is fitted to the flange portion of the housing such that the ramp surfaces abut one another to form a continuous ramp surface from each air inlet aperture into the air chambers. A rotating fan member is mounted to the armature shaft and is housed within a shroud cover fitted to the motor housing.Type: GrantFiled: August 18, 2000Date of Patent: October 30, 2001Assignee: Ametek, Inc.Inventors: Michael L.
