Lamination For A Permanent Magnet Machine

View page
US Patent:
20140283373, Sep 25, 2014
Filed:
May 7, 2014
Appl. No.:
14/271922
Inventors:
- Fort Smith AR, US
Richard F. Schiferl - Chagrin Falls OH, US
Stephen D. Umans - Belmont MA, US
Robert F. McElveen - Anderson SC, US
William E. Martin - Greenville SC, US
International Classification:
H02K 15/03
US Classification:
29598
Abstract:
A method includes forming a lamination that may be used in a rotor of an interior permanent magnet motor or further processed for use in a line-start interior permanent magnet motor. The lamination has been optimized for low cogging, minimal usage of magnet material, and maximum torque per ampere and may be further processed to include rotor bars slots to allow the lamination's use in connection with an LSIPM. In accordance with the method, the lamination is formed with magnet slots that are radially inward of the outer diameter. The magnet slots are formed in a plurality of V-shaped arrangements. Each V-shaped arrangement has a leading edge and a trailing edge. The leading edge and trailing edge are arranged such that when the leading edge aligns with a stator tooth, the respective trailing edge is generally not aligned with a stator tooth.

Asymmetric Rotor For A Line Start Permanent Magnet Machine

View page
US Patent:
20140285050, Sep 25, 2014
Filed:
May 5, 2014
Appl. No.:
14/269456
Inventors:
- Fort Smith AR, US
Richard F. Schiferl - Chagrin Falls OH, US
Stephen D. Umans - Belmont MA, US
International Classification:
H02K 21/46
US Classification:
31015678
Abstract:
A rotor comprises laminations with a plurality of rotor bar slots with an asymmetric arrangement about the rotor. The laminations also have magnet slots equiangularly spaced about the rotor. The magnet slots extend near to the rotor outer diameter and have permanent magnets disposed therein creating magnetic poles. The magnet slots may be formed longer than the permanent magnets disposed therein and define one or more magnet slot apertures. The permanent magnets define a number of poles and a pole pitch. The rotor bar slots are spaced from adjacent magnet slots by a distance that is at least 4% of the pole pitch. Conductive material is disposed in the rotor bar slots, and in some embodiments, may be disposed in the magnet slot apertures.

Micro-Channel Heat Exchanger For Stator Of Electrical Machine With Supply Header

View page
US Patent:
20140265666, Sep 18, 2014
Filed:
Mar 13, 2014
Appl. No.:
14/208747
Inventors:
- Fort Smith AR, US
Andreas A. Meyer - Richmond Heights OH, US
Richard F. Schiferl - Chagrin Falls OH, US
Qimin Dong - Greer SC, US
Michael Brinkmann - Broadview Heights OH, US
Assignee:
Baldor Electric Company - Fort Smith AR
International Classification:
H02K 1/20
US Classification:
310 59
Abstract:
An electric machine has a stator that comprises a plurality of laminations with teeth and cooling apertures about a central opening. When the laminations are stacked to form the stator core, the teeth of adjacent laminations cooperate to form slots disposed circumferentially about the central opening that are configured to receive a plurality of stator windings, and the cooling apertures angularly spaced about the central opening cooperate to form cooling manifolds that extend along a length of the stator core. A portion of the laminations has their cooling apertures offset from other laminations in the stack in a manner to create a plurality of flow paths transverse to the manifolds. The transverse flow paths extend angularly between laminations and adjacent manifolds. A header assembly directs flow into and out of the stator core.
