Abstract
A method of joining a lamination stack of an electromagnetic actuator to a housing of the actuator includes providing a lamination stack having at least one surface feature. A mold is provided to define the housing. The lamination stack is inserted into the mold such that the surface feature of the lamination stack will define a mating surface feature in the housing. Material is cast around at least a portion of lamination stack to define the housing such that the surface feature of the lamination stack is engaged with the surface feature of the housing, thereby joining the lamination stack to the housing. The assembly of the lamination stack and housing is then removed from the mold.
Claims15
A method of joining a lamination stack of an electromagnetic actuator to a housing of the actuator, the method comprising:
- providing a lamination stack having at least one shaped feature,
- providing a mold to define the housing,
- inserting the lamination stack into the mold such that said shaped feature of said lamination stack will define a mating shaped feature in said housing, and
- casting material around at least a portion of said lamination stack to define said housing such that said shaped feature of said lamination stack is engaged with said shaped feature of said housing, thereby joining said lamination stack to said housing.
A lamination and housing assembly for an electromagnetic actuator comprising:
- a lamination stack comprising a plurality of individual laminations, said lamination stack including a bottom surface and a shaped feature associated with said bottom surface, and
- a housing having an upper surface and a shaped feature associated with said upper surface, said housing receiving said lamination stack such that said shaped feature of said lamination stack is engaged with said shaped feature of said housing, with said bottom surface of said lamination stack contacting said upper surface of said housing.
