Description
Technical Field
The present invention relates to an interconnection assembly for a rotary electric machine, and to a rotary electric machine equipped with an interconnection assembly of this type.
Background
The rotating electrical machine is preferably a multiphase electromechanical device which makes it possible to convert electrical energy into mechanical energy, or vice versa. A known application of rotating electrical machines in the motor vehicle industry is alternator starters, i.e. devices for stopping and automatically restarting the heat engine of a motor vehicle, which allow to reduce fuel consumption and pollution, for example during a brief stop at a red light.
A rotating electrical machine comprising:
-an electric motor comprising a rotor and a stator;
-a control system for electrically controlling the electric motor.
More specifically, the control system comprises a power module making it possible to define the value of the current circulating in each electric phase of the stator of the electric motor, and a control device comprising a control module making it possible to control the power module as a function of certain environmental parameters and of data measured on board the motor vehicle.
The control system may also include a heat sink body and a cover that protects the electrical components of the control system (such as the power module and the control module).
In a known manner, using interconnectors, the interconnectors make it possible to establish a correspondence between the ends of the phase windings of the stator and power modules, which are angularly offset with respect to the ends of the phase windings of the stator.
Patent application FR3056842 describes a machine of this type in which the ends of the phase windings of the stator are welded to the terminals of the interconnector. The terminals of the interconnector are electrically connected to the connection terminals by rails on which supports made of insulating material are overmolded. The connection terminals project in the axial direction, i.e. in the same direction as the axis of rotation of the motor rotor. The connection terminal is electrically connected to a tab of the power module. Since the screws extend in a radial direction (i.e. a direction perpendicular to the axis of rotation of the motor rotor), an electrical connection of each connection terminal to the lug of the power module is provided.
Such a connection by means of screws extending in radial direction is very limited. In practice, this requires the provision of a passage area for the screw driver.
These pass through areas for the screw driver can complicate the shape of the surrounding parts. For example, it may be desirable to have an uneven interface between the radiator body and the cover of the control system. This uneven interface results in a more complex seal being applied between the radiator body and the cover of the control system.
It is only after the threaded connection between the connection terminal and the lug of the power module that it is necessary to assemble the heat sink body and/or the cover of the control system. This is a significant industrial constraint. In fact, it is not possible to assemble the finished control system on the motor.
Furthermore, tightening is a particularly slow assembly process, requiring complex automated tools, in particular because of the handling of the screws.
Furthermore, this type of screw connection is not removable, i.e. it is not possible to separate the connection terminals from the lugs of the power module without disassembling or breaking the connection.
Disclosure of Invention
The object of the present invention is to propose an interconnection assembly for a rotating electrical machine in order to solve at least in most cases the above-mentioned problems.
The invention relates to an interconnection assembly for a rotating electrical machine, comprising:
-a first interconnection module comprising a first terminal designed to be electrically connected to an end of a phase winding of a stator of an electric machine, and a first connection terminal electrically connected to the first terminal;
a second interconnection module comprising a second connection terminal electrically connected to a second terminal designed to be electrically connected to an electronic control module or to an electronic power module of the rotating electrical machine,
the first connection terminal and the second connection terminal are configured to be electrically contacted by a connection that is removable in a connection direction, in particular in the direction of the rotation axis O of the electric motor.
The use of this type of interconnection assembly facilitates the assembly of the system for controlling a rotating electrical machine on an electric motor. In fact, the assembly does not require screws or other non-removable electrical connection means in order to establish an electrical connection between the phase windings of the electric motor and the electronic module of the control system. The assembly is faster and does not require complex tools.
This type of interconnect assembly also facilitates separation of the control system from the motor, for example, during disassembly. Thus, the control system or motor can be replaced without complicated or damaging disassembly.
Furthermore, this removable connection can be reduced in size, since it does not require additional fixing systems, such as screws.
The interconnection assembly allows for greater flexibility in the production of the rotating electrical machine. In fact, it is possible to produce the control system with the second interconnection module fixed thereto and the electric motor with the first interconnection module fixed thereto separately and then assemble them in a final step.
According to an additional feature of the invention, the electrical contact between the first connection terminal and the second connection terminal is ensured by an electrically conductive elastic element.
The use of an electrically conductive elastic element makes it possible to improve the electrical contact between the first connection terminal and the second connection terminal, while allowing shape tolerances of the connection terminals and positioning tolerances between the wider connection terminals, which tolerances can be compensated by the elasticity of the electrically conductive elastic element.
According to an additional feature of the invention, the electrical contact between the first connection terminal and the second connection terminal is ensured by plugging. One of the first connection terminal and the second connection terminal includes a male connection unit, and the other of the first connection terminal and the second connection terminal includes a female connection unit.
According to an additional feature of the invention, the female connection unit comprises a cylindrical socket and the male connection unit comprises a plug insertable into the cylindrical socket.
According to an additional feature of the invention, the first terminals and the first connection terminals of the first interconnection module are overmoulded in a first support made of an electrically insulating material, in particular a plastic material, and/or the second terminals and the second connection terminals of the second interconnection module are overmoulded in a second support made of an electrically insulating material, in particular a plastic material.
According to an additional feature of the invention, the first interconnection module comprises a plurality of first terminals and first connection terminals, and/or the second interconnection module comprises a plurality of second terminals and second connection terminals.
According to an additional feature of the invention, the first interconnect module comprises a sensor.
According to an additional feature of the invention, the sensor is a temperature sensor and/or an angular position sensor, which can measure the angular position and/or the speed of the rotor of the electric motor.
According to an additional feature of the invention, the first interconnection module and/or the second interconnection module comprises a magnetic core provided with an air gap in which the hall effect sensor is designed to be placed to measure the current.
The present invention also relates to a rotary electric machine comprising:
-an interconnect assembly;
-an electric motor comprising a stator comprising a body and a winding formed by a plurality of phase windings, each phase winding being electrically connected to at least one end of a first terminal of a first interconnection module;
a system for electronic control of a rotating electrical machine, electrically connected to the second terminal of the second interconnection module and comprising a radiator body housing the electronic control module and/or the electronic power module,
the first interconnection module is integral with the body of the stator and the second interconnection module is integral with the heat sink body.
According to an additional feature of the invention, the heat sink body is closed by a cover, the interface area between the heat sink body and the cover being flat.
The interface area between the heat sink body and the cover allows for easy installation of the seal. In particular, it is easier to deposit the seal in an automated manner.
