DeepDrive to unveil new central drive unit at IAA Mobility

DeepDrive, a Munich-based deep-tech firm backed by BMW and Continental (earlier post), will unveil a brand new central drive unit for electrical automobiles as a world premiere on the IAA Mobility 2023 (4 – 10 September). The corporate says it’s actively working with a number of main OEMs within the DeepDrive drive unit. First collection deployments are deliberate for 2027.

DeepDrive has developed a cost- and resource-efficient dual-rotor motor, extending the vary of electrical automobiles. The patented DeepDrive dual-rotor, radial flux machine combines an interior and outer rotor with two air gaps and advantages from very excessive materials utilization and lowest iron losses. The important thing enabler for the dual-rotor idea is a brand new distributed winding idea with a slot-filling issue above 80%.

Along with the wheel hub drive introduced for the primary time
on the IAA Mobility 2021, the brand new central drive primarily based on the identical expertise is
now following as one other world premiere.

The DeepDrive drive unit minimizes materials consumption. The optimized design considerably reduces the necessity for magnets (-50% in comparison with the competitors) and iron (-80% in comparison with the competitors) and underlines the corporate‘s dedication to resource-efficient improvements.

DeepDrive’s drive unit can be out there in two variants that meet totally different market wants. Each variants mix the motor with a two-stage spur gear and a
extremely environment friendly SiC inverter.

• The DeepDrive CSD 450 provides an engine torque of 430 N·m with an output energy of 230 kW
  and is suited as the principle drive for mainstream functions in electrical automobiles
  (entrance or rear-wheel drive as much as the C section) in addition to all-wheel drive ideas within the premium section. With variable gear ratios, output torques of between 2,700 and three,800 N·m might be achieved.

• The DeepDrive CSD 700 delivers as much as 5,400 N·m output torque with an output energy of 350 kW and is positioned as the principle drive for premium automobiles within the D-segment class and all- wheel drive configurations.

Each variants supply excessive efficiencies in vast working ranges and allow cost-effective but long-range electrical automobiles.

Each drive items function an built-in SiC-inverter and a two-stage, spur gearbox with coaxial output shaft that minimizes house consumption at a really low value degree. Gearbox ratio for the CSD 450 might be diversified in a spread from 6.4:1 to 9:1; for the CSD 700, the vary is from 6:1 to eight:1.
