Assignee:

Warner-Lambert Company LLC - Morris Plains NJ

International Classification:

C07D 471/04
C07D 487/04

US Classification:

544279

Abstract:

Assignee:

Danotek Motion Technologies - Ann Arbor MI

International Classification:

H02K 9/00

US Classification:

310 54, 310 52

Abstract:

The invention is a generator and cooling mechanism. The generator includes a rotor comprising a shaft with a skewed alignment of magnets on a ring, a stator of toothed laminations with coils wound around the teeth, and a housing with cooling chambers. The housing has annular subchambers arranged successively along the length of the generator in such a way that cooling fluid must flow to the opposite side of the generator to pass into the next chamber. Because the housing is highly heat conductive, this structure of annular subchambers increases the uniformity of the fluid temperature.

International Classification:

H02K 21/12

US Classification:

31015601, 31015647, 31015401

Abstract:

A direct-drive generator and assembly procedure for that generator include a permanent magnet assembly that is partitioned and assembled piece-by-piece after the rotor and stator have been attached. The magnets are attached to a plate in columns, and adjacent columns have a N-S orientation. The air gap between the rotor and stator is variable, and application of an input torque produces a first cogging torque in a first direction due to the variable air gap that offsets a second cogging torque in a second opposite direction.

International Classification:

H02K 15/03
H02K 1/30

US Classification:

29596, 31015626

Abstract:

A method for assembling a direct drive generator assembly includes the steps of placing a rotor over a stator, leaving a gap therebetween. A magnetic hub is assembled using adjacent columns of magnets having opposed orientation, and placed in the air gap. Application of an input torque to generate cogging torque in first direction that offsets coggery torque in second direction.

International Classification:

H02K 11/00

H02K 9/18

US Classification:

310064000, 31006800B, 31006800C, 310089000

Abstract:

The present invention is an integrated brushless permanent-magnet motor with the circuit board controller in the same chamber as the rotor and stator. Including the circuit board controller in the same chamber as the rotor and stator allows for a more compact motor. The motor may include fins on its housing exterior such that the heat generated by the motor flows out of the housing through the fins, cooling the motor. The invention may also include features designed to reduce cogging.
