INDIRECT ROTOR COOLING OF ELECTRIC MACHINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240030766 titled 'INDIRECT ROTOR COOLING OF ELECTRIC MACHINE
Simplified Explanation
The abstract describes an electric machine that consists of a rotor and a stator, with a cold plate positioned near the rotor. The cold plate is stationary and creates a gap between itself and the rotor. The cold plate has coolant pathways that allow thermal energy from the rotor to be transferred to a flow of coolant circulating through the pathways.
- The electric machine includes a rotor and a stator.
- A cold plate is positioned near the rotor.
- The cold plate is stationary and creates a gap between itself and the rotor.
- The cold plate has coolant pathways.
- Thermal energy from the rotor is transferred to a flow of coolant circulating through the pathways.
Potential Applications:
- Electric motors in vehicles
- Industrial machinery
- Power generation systems
Problems Solved:
- Efficient cooling of electric machines
- Preventing overheating and damage to the rotor
- Improving overall performance and longevity of the machine
Benefits:
- Enhanced thermal management
- Increased efficiency and reliability
- Extended lifespan of the electric machine
- Improved performance in demanding applications
Original Abstract Submitted
an electric machine includes a rotor located at and rotatable about a central axis and a stator positioned proximate to the rotor and defining a radial machine gap between the rotor and the stator. a cold plate is positioned proximate to the rotor. the cold plate is rotationally stationary relative to the central axis and is spaced apart from the rotor to define a cold plate gap between the cold plate and the rotor. the cold plate includes one or more coolant pathways therein such that thermal energy from the rotor is transferred to a flow of coolant circulated through the one or more coolant pathways.
