Abstract
A stator for an electrical machine, in particular for an electromotive drive machine for an electric or hybrid vehicle, includes a stator core stack with a stator yoke and a number of radial stator teeth, as well as a corresponding number of stator slots, arranged between the stator teeth, for receiving a stator winding. A cooling apparatus has a number of cooling channels, each of which runs axially in one of the stator slots.
Claims20
A stator for an electric machine, comprising:
- a stator laminated core having a stator yoke and a number of radially oriented stator teeth, wherein a corresponding number of stator slots are arranged between the stator teeth to receive a stator winding;
- and
- a cooling apparatus having a number of cooling channels, which cooling channels are each arranged so as to run axially in one of the stator slots,
- wherein each of the stator slots comprises a narrowed section that is configured to hold a respective one of the cooling channels.
A cooling apparatus for a stator of an electric machine having a stator laminated core with a stator yoke and a number of radially oriented stator teeth between which stator slots are arranged to receive a stator winding, the coolant apparatus comprising:
- a number of cooling channels configured in a manner such that, when assembled together with the stator, each cooling channel extends axially in a respective one of the stator slots,
- wherein each of the stator slots comprises a narrowed section that is configured to hold a respective one of the cooling channels.
