Stator for an electric motor

Abstract: The present invention pertains to a stator for an electric motor, composed of a stator core assembly (2), stator windings (3) and, arranged at one end of the stator core assembly (2), an interconnecting arrangement (4) for the stator windings (3). An interconnecting arrangement (4) features an insulating part (9) with slotted chambers (11) in order to accept electrical connecting leads (12), insulated from each other, in order to interconnect the wire ends (7) of the stator windings (3).

Stator for an electric motor having a temperature monitor

Abstract: A stator for an electric motor, in particular for an external rotor motor, includes a laminated stator core which is provided with a stator winding and having a connecting arrangement, which is arranged on one end side in the region of an end winding of the stator winding, for the purpose of electrically connecting winding wire ends of the stator winding and connecting wires of a temperature monitor connected upstream of the stator winding The connecting arrangement has an insulating switching disk which covers the region of the end winding, in particular in the form of a cap The temperature monitor is held in the switching disk in an integrated manner such that, on the end-winding side, it rests between the Mater winding and the switching disk such that it is in thermally conductive bearing contact with said stator winding

Compact high power alternator

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.

Insulator for stator assembly of brushless DC motor

Abstract: An insulator for a stator assembly includes at least a first insulator adapted to be mounted to the stator core and structured to insulate the stator core from the coils. The at least one insulator includes structure to perform at least one additional function. For example, the structure may include a support member to support and/or locate the PCBA on the stator core, a wire guide to guide cross-over wires that form a connection between coils, and/or positioning structure to precisely position the PCBA with respect to the coils.

Electric rotating machine

Abstract: An electric rotating machine capable of lowering the temperature of a rotor disposed, wherein at least one of closed ventilation loops for cooling is formed, one of the loops constituting a ventilation passage communicating with an exhaust side through a heat source of the end of the generator to a cooler, thereby to supply cooling wind to the rotor after it passes through the cooler.
