Turntide Technologies, Inc. (Turntide), developer of sustainability technologies, will introduce its Turntide NetZero AXM axial flux motor line, a reliable power- and torque-dense motor technology during CONEXPO-CON/AGG (CONEXPO) at Booth S63613 in the South Hall, Level 1. This marks the expansion of the Turntide Electrification suite of products, and the first in a series of integrated powertrain products that Turntide will introduce in 2023.
“As the construction industry undergoes a rapid transformation, the demand for powerful, efficient, and sustainable equipment continues to rise. Axial flux motor technology is a gamechanger in the world of electromechanical engineering by providing smaller, lighter, and more powerful motors that help reduce energy consumption and improve overall equipment performance,” said Mark Cox, general manager of Turntide’s transport business unit. “At Turntide, we are committed to driving innovation and advancing the adoption of axial flux motors [because] we believe these will pave the way for a more sustainable future.”
Turntide's axial flux motor design, which features a dual stator and single rotor configuration, offers a range of benefits compared to traditional radial flux motors. These benefits include:
- A more compact size
- 30% to 40% greater torque
- Higher power density
- Precise control
These motors can replace radial flux motors in applications such as commercial vehicles, construction machinery, hybrid marine vessels, industrial robots, FC radiator fans, hydraulic pumps and any application in which space and weight are limited and efficiency matters.
Unlike radial flux motors, axial flux motors have a distinct geometry in which the magnetic flux direction is parallel to the motor’s rotation axis. This design provides improved torque and power while using the same electrical components as radial flux motors. Additionally, because of their extremely low axial length-to-diameter ratio, axial flux motors are "flat" and have a smaller and lighter form factor than radial motors.
Construction equipment is estimated to generate around 400 metric tons of carbon dioxde emissions per year, roughly 1.1% of global emissions. As a result, the decarbonization of off-highway mobile machines is considered an important factor in efforts to limit global climate change. Additionally, electrified construction machines produce no emissions on-site, making them more versatile to use indoors, underground and in other locations with limited ventilation.
Recently, Turntide has advanced the motor's design, size, scalability and production readiness. Leveraging digital twins and simulation software from Ansys, Turntide is accelerating design cycles to ensure safety, reliability and full-power performance in the most rigorous and extreme conditions.
