Abstract
The invention relates to a method for producing an electric motor housing, comprising the steps: (a) positioning at least stator part (30) in a support body interior chamber of support body (22), (b) arranging a casting core (42) on the support body (22), (c) then casting the liquid metal around the support body (22) and the casting core (42), resulting in a torque-proof connection between stator part (30) and a casting (26) as a result of the solidification of the liquid metal.
Claims19
A method for producing an electric motor housing, comprising:
- (a) positioning at least one stator part in a support body interior chamber of a support body,
- (b) arranging a casting core on the support body,
- (c) casting liquid metal around the support body and the casting core to produce a torque-proof connection between the at least one stator part and a casting as a result of solidification of the liquid metal.
The method according to one of the preceding claims, further comprising:
- after arranging the support body in the casting mould, closing the casting mould by moving at least two mould parts towards each other,
- wherein when the at least two mould parts are moved towards each other, the support body is sealed against the casting mould.
A cast part production system for producing an electric motor housing, comprising:
- (a) a salt moulded part production machine for producing a salt moulded part that comprises
- (i) a mould for a salt moulded part,
- (ii) an insertion device designed to automatically enclose a support body and introduce a salt or a salt mixture in liquid form into the mould for the salt moulded part so that the salt or salt mixture comes into contact with the support body, and
- (iii) a de-moulding device for de-moulding the salt moulded part, resulting in a pre-blank,
- (b) an injection moulding machine for injection moulding metal around the salt moulded part resulting in a blank, wherein the injection moulding machine comprises an injection mould configured to enclose the support body, and
- (c) a salt moulded part removal device for dissolving the salt moulded part resulting in the electric motor housing.
An electric motor, comprising:
- (a) a one-piece cast electric motor housing in which a cooling channel extends, wherein the cooling channel, at least in sections, does not extend in a straight line,
- (b) a housing or housing part is produced entirely from identical casting material.
