Technical description

The rotor shaft is used to hold the laminated core and ensures torque transmission from the electromagnetic area to the mechanical area. The built rotor shaft enables the integration of further functions inside the shaft (e.g. cooling). Another advantage is the reduction of the weight reduction.

Customer benefits / unique selling propositions

• Stress-related combination of different materials on one shaft

• Integration of functions possible by using the available space in the rotor shaft

• Less machining effort due to design close to finished size

• 100% quality data recording for each connection

Technical description

Today's thermal management market is dominated by chemical refrigerants. The environmental consequence of their usage is widely known and is currently leading to a shift to natural refrigerants like R744 (CO₂). In comparison to R290 (Propane) there are efficiency advantages for R744 regarding heat pump application and its non-flammability. But there is a main challenge to overcome: The pressure level of R744 refrigeration circuits is about five times higher in contrast to R290 and also to the common synthetic refrigerant cycles of R134 and R1234yf.

To tackle this challenge, we developed a compressor that uses its low inner leakage and low lubrication demands to ensure great efficiency, durability and load point flexibility. The compressor excels at high mass flows but still enables to provide a low mass flow without start/stop. Additionally, the compressor allows continuously operation at very high-pressure ratios and vapor phase inlet conditions.
