The Turntide AF430S Axial Flux Motor is designed to meet the unique needs associated with the electrification and hybridization of equipment and vehicles, from off-highway to premium automotive. Its compact design, exceptional power density, and ease of integration make it ideal for OEMs seeking to accelerate electrification or hybridization without costly redesigns.
Speeds Electric and Hybrid Integration
The AF430S axial flux motor solves key challenges associated with long lead times and high-price, one-off manufacturing, delivering a scalable and cost-efficient alternative. Designed for seamless OEM integration, it provides a cost-efficient path to electrification across applications such as electric and hybrid vehicles, construction equipment, marine vessels, and high-speed transportation.
It offers exceptional power density, with one of the highest peak power and torque ratings in its class, at over 7.2 kW/kg and 20.5 Nm/kg at 800 VDC. The compact and lightweight design gives OEMs a powerful combination of high vehicle performance and quiet, smooth, low-vibration operation.
High Efficiency and Lower Lifetime Cost
The motor's advanced cooling design, robust construction, and configurable options offer durability, versatility, and reliable performance across vehicle and equipment platforms, reducing the total cost of ownership across the lifecycle of the vehicle or equipment.
Tailored for Space Constrained, High-Performance Platforms
The AF430S features a short and compact motor axial length and unique magnetic topology. Combined with electromagnetic, thermal, and manufacturing optimization results in a breakthrough motor that offers smooth, quiet operation with low torque ripple and low cogging torque while supporting inverter supply voltages of up to 850 VDC.
Key Features Include:
- Peak efficiency of 96% at continuous load, equivalent to the highest efficiency class of IE4
- Indirect liquid cooling using standard medium of water and ethylene glycol for high power density
- Through-shaft female spline as per ISO 4156, enabling dual output system integration
- Designed for operation up to 850 VDC and peak overvoltage support up to 1 kV VDC
- Low cogging torque and torque ripple, allowing smooth system operation and low NVH characteristics
- Axially stackable motor design platform, enabling scaled torque and power levels
