11/710239
Inventors:
Charles Y. Lafontaine - Berthoud CO, US
Harold C. Scott - Lafayette CO, US
Harold C. Scott - Lafayette CO, US
Assignee:
Magnetic Applications, Inc. - Lafayette CO
International Classification:
H02K 9/00
US Classification:
310 58
Abstract:
A compact, high power, power conversion apparatus including a rotor and a stator. The rotor includes a cylindrical casing, and a predetermined number of permanent magnets disposed on the casing, and is adapted for rotation about the axis of the casing. The stator includes a core and a plurality of sets of conductive windings, each set including a predetermined number of individual conductive windings and associated with an electrical phase. A respective collecting conductor is associated with each set of conductive windings, with each individual conductive winding of the set being electrically connected to the associated collecting conductor. The respective collecting conductors are disposed in a coolant flow path a coolant flow path directing coolant into contact with the stator windings, electrically isolated from each other and spaced apart from each other and from the windings. Collecting conductors in the form of continuous rings and in the form of a plurality of arcs are disclosed.

US Classification:
310 71, 310 68 C
Abstract:

The control system includes a zero crossing detector and variable ramp generator for generating control signals to a switching rectifier to generate a regulated DC signal.
Compact High Power Alternator
US Patent:
7768166, Aug 3, 2010
Filed:
Dec 6, 2005
Appl. No.:
11/295888
Inventors:
Charles Y. Lafontaine - Berthoud CO, US
Harold C. Scott - Lafayette CO, US
Harold C. Scott - Lafayette CO, US
Assignee:
Magnetic Applications, Inc. - Lafayette CO
International Classification:
H02K 21/22
US Classification:
310 90, 31015614
Abstract:
An apparatus for converting between mechanical and electrical energy, particularly suited for use as a compact high power alternator for automotive use and “remove and replace” retrofitting of existing vehicles. The apparatus includes a rotor with permanent magnets, a stator with a winding, and a cooling system. Mechanisms to prevent the rotor magnets from clashing with the stator by minimizing rotor displacement, and absorbing unacceptable rotor displacement are disclosed. Various open and closed cooling systems are described. Cooling is facilitated by, for example, loosely wrapping the winding end turns, use of an asynchronous airflow source, and/or directing coolant through conduits extending through the stator into thermal contact with the windings.

US Patent:
8018108, Sep 13, 2011

Appl. No.:
12/368212
Inventors:
Charles Y. Lafontaine - Berthoud CO, US
Harold C. Scott - Lafayette CO, US
Harold C. Scott - Lafayette CO, US
Assignee:
Magnetic Applications, Inc. - Lafayette CO
International Classification:
H02K 7/20
US Classification:
310112, 310 59
Abstract:
An apparatus for converting between mechanical and electrical energy, particularly suited for use as a compact high power alternator for automotive use and “remove and replace” retrofitting of existing vehicles. Various aspects of the invention provide a means of significantly increasing the output of permanent magnet alternators while addressing the issues of radial loading applied to a permanent magnet alternator rotor. Another aspect of the invention allows for the production of power in two discrete voltages. An aspect of this invention allows for a marked increase in output capability without increasing axial length through the use of magnetic fringing. One aspect of the invention offers an effective means of mounting a skewed stack that eliminates or reduces cogging that is present in a permanent magnet machine without negatively impacting airflow. Another aspect of the invention reduces cogging by radially offsetting opposing magnets of a dual rotor permanent magnet machine.

International Classification:
H02K 21/22
US Classification:

Abstract:
An apparatus for converting between mechanical and electrical energy, particularly suited for use as a compact high power alternator for automotive use and “remove and replace” retrofitting of existing vehicles. The apparatus comprises a rotor with permanent magnets, a stator with a winding, and a cooling system. Mechanisms to prevent the rotor magnets from clashing with the stator by minimizing rotor displacement, and absorbing unacceptable rotor displacement are disclosed. The cooling system directs coolant flow into thermal contact with at least one of the winding and magnets, and includes at least one passageway through the stator core. Various open and closed cooling systems are described. Cooling is facilitated by, for example, loosely wrapping the winding end turns, use of an asynchronous airflow source, and/or directing coolant through conduits extending through the stator into thermal contact with the windings.
