Definitions
- the invention relates to an electric motor comprising a stator having at least three stator windings, a rotor which is rotatable about an axis of rotation relative to the stator, and a power unit for controlling the stator windings.
- a generic electric motor which has a rotor and a stator.
- the stator comprises stator windings and is arranged in a motor housing.
- the rotor is rotatable relative to the stator.
- a generic electric motor also includes a converter for supplying the stator with electrical energy.
- the converter is supplied with a direct voltage, for example, and provides a three-phase output voltage for the stator.
- the converter includes a power section and a control module.
- the power section includes several switches that are controlled by the control module.
- a power section for a converter which has a heat sink.
- Heat-generating components such as semiconductor switches, are arranged at regular intervals on the outside of the heat sink.
- a motor device with an integrated electronic circuit is known from DE 102010 017 519 B4.
- the motor device has a motor, a heat sink and an electronic circuit which is attached to the motor housing.
- a three-phase inverter system for a motor is known from DE 102017213 395 A1.
- the three-phase inverter system has first, second and third output units and first, second and third capacitors which are arranged radially to form a hexagonal shape.
- an electronic module which contains a cooling tower having first and second axial ends.
- the cooling tower extends around a central module axis.
- An electronic drive device is known from WO 2019/223882 A1.
- the drive device comprises a stator and a rotor. Drive windings are interconnected on an interconnection element.
- the converter is usually designed as a separate component and located near the electric motor.
- the converter therefore requires space. It is also known to locate the converter away from the stator, for example in a control cabinet. In this case, ohmic losses occur in the supply lines from the converter to the stator.
- the invention is based on the object of further developing an electric motor.
- An electric motor comprises a stator which has at least three stator windings, a rotor which can be rotated about an axis of rotation relative to the stator, and a power unit for controlling the stator windings.
- the power unit has an upper busbar to which a positive voltage is applied, a lower busbar to which a negative voltage is applied, at least three busbars which are each electrically connected to one of the stator windings, at least three upper switches which are electrically connected between the upper busbar and one of the busbars, and at least three lower switches which are electrically connected between the lower busbar and one of the busbars.
- the electric motor comprises a hollow cylindrical holding element which coaxially surrounds the axis of rotation.
- the switches are arranged offset from one another in the circumferential direction on an inner surface of the holding element facing the axis of rotation.
- the power section of the converter is thus arranged in the immediate vicinity of the stator or integrated into the stator.
- the arrangement of the switches according to the invention significantly reduces the space required for the power section.
- a control module for controlling the switches of the power section can be arranged away from the stator, since no significant ohmic losses occur in the control lines that connect the control module to the switches.
- the stator has a hollow cylindrical stator housing in which the stator windings are arranged, and the holding element is connected to the stator housing in the axial direction.
- the upper busbar, the lower busbar and the busbars are therefore also connected to the stator housing in the axial direction. This further reduces the space required for the power section.
- the holding element consists of an electrically insulating material or has an electrically insulating coating at least on the inner surface facing the axis of rotation.
- the electrically insulating coating allows the holding element to be made of a metallic material.
- the holding element is formed in one piece with the stator housing.
- the busbars, the upper busbar and the lower busbar are arranged on the inner surface of the holding element facing the axis of rotation and each have an insulating coating facing the holding element.
- This embodiment also allows the holding element to be made from a metallic material.
- the holding element is formed in one piece with the stator housing.
- the upper busbar is arranged offset in the circumferential direction from the lower busbar on the inner surface of the holding element facing the axis of rotation.
- the upper busbar and the lower busbar extend together, preferably approximately over the entire circumference of the inner surface of the holding element. This reduces the expansion of the busbars and the holding element in the axial direction. Furthermore, the waste heat generated in the switches is dissipated relatively quickly.
- the upper busbar is arranged offset in the axial direction from the lower busbar on the inner surface of the holding element facing the axis of rotation. This makes the internal connection between the busbars, the switches and the busbars easy to implement.
- the busbars are arranged offset from one another in the circumferential direction on the inner surface of the holding element facing the axis of rotation.
- the busbars preferably extend together approximately over the entire circumference of the inner surface of the holding element. This reduces the extent of the busbars and the holding element in the axial direction.
- the busbars are arranged offset in the axial direction to the upper busbar and to the lower busbar on the inner surface of the holding element facing the axis of rotation. This makes the internal connection between the busbars, the switches and the busbars easy to implement.
- the busbars are arranged in the axial direction between the upper busbar and the lower busbar on the inner surface of the holding element facing the axis of rotation. This makes the internal connection between the busbars, the switches and the busbars particularly easy to implement.
- the switches are each designed as field-effect transistors and each have a gate connection, a source connection and a drain connection.
- Field-effect transistors can be controlled at relatively high frequencies and cause relatively low switching losses with relatively low ohmic losses when switched on.
- the drain connection of a field-effect transistor can be connected in a material-locking manner to a busbar or a busbar. Material-locking connections include in particular laser welding and soldering.
- the drain connections of the upper switches are integrally connected to the upper busbar.
- the upper busbar is arranged in the radial direction between the holding element and the upper switches. Heat that is generated in the upper switches is dissipated outwards in the radial direction through the upper busbar and the holding element.
- the drain connections of the lower switches are integrally connected to the lower busbar.
- the lower busbar is arranged in the radial direction between the holding element and the lower switches. Heat that is generated in the lower switches is dissipated outwards in the radial direction through the lower busbar and the holding element.
- the drain connections of the upper switches are each connected in a materially bonded manner to one of the busbars.
- the busbars are arranged in the radial direction between the holding element and one of the upper switches. Heat that is generated in the upper switches is dissipated radially outwards through the respective busbar and the holding element and partially into the windings.
- the drain connections of the lower switches are each connected in a materially bonded manner to one of the busbars.
- the busbars are arranged in the radial direction between the holding element and one of the lower switches. Heat that is generated in the lower switches is dissipated radially outwards through the respective busbar and the holding element and partially into the windings.
- the power unit has at least one intermediate circuit capacitor which is connected between the upper busbar and the lower busbar and is arranged on the inner surface of the holding element facing the axis of rotation, and/or the power unit has at least one interference suppression capacitor which is arranged on the inner surface of the holding element facing the axis of rotation.
- the power unit has at least three current sensors, which are arranged on the inner surface of the holding element facing the axis of rotation.
