Abstract
The disclosure relates to electronics of an electric motor of a motor vehicle, having a connection unit that is placed in electrical contact with a circuit board and attached thereto. The connection unit has a number of leadframes that are stabilized with respect to one another. The connection unit at least partly forms a connector socket for a mating connector, and the connection unit at least partly forms a contact point for an electromagnet of the electric motor.
Claims19
A brushless electric motor of a motor vehicle, comprising:
- a connection unit that is in electrical contact with a circuit board and attached thereto, wherein the circuit board includes a number of leadframes encapsulated by a thermoplastic material, wherein the thermoplastic material is configured to stabilize each of the leadframes with respect to one another and,
- wherein the connection unit at least partly forms a connector socket for a mating connector and a contact point for an electromagnet of the electric motor;
- and
- a covering formed of a thermoset material, the thermoset material extends to an edge of the thermoplastic material and is configured to stabilize the thermoplastic material.
An electric motor of a motor vehicle, comprising:
- a connection unit in electrical contact with a circuit board, wherein the circuit board includes a number of leadframes encapsulated by a thermoplastic material, wherein the thermoplastic material is configured to stabilize each of the leadframes with respect to one another, wherein the connection unit includes a connector socket for a mating connector and a contact point for an electromagnet of the electric motor;
- a heat sink in thermal contact with the circuit board;
- and
- a covering produced from a thermoset material that completely surrounds the circuit board and at least partly surrounds the connection unit, wherein the thermoset material extends to an edge of the thermoplastic material and is configured to stabilize the thermoplastic material.
A method of manufacturing electronics of an electric motor of a motor vehicle, comprising:
- punching out a plurality of leadframes from sheet metal;
- encapsulating the plurality of leadframes with a thermoplastic;
- placing a connection unit of the electric motor in electrical contact with a circuit board that has a plurality of leadframes, wherein the connection unit includes a connector socket for a mating connector and a contact point for an electromagnet of the electric motor;
- and
- surrounding the circuit board and the connection unit via a covering produced from a thermoset material, wherein the thermoset material extends to an edge of the thermoplastic material and stabilizes the thermoplastic material.
