Turntide Technologies presents its axial flux motor range, one of the most reliable power- and torque-dense types of motor technologies. The motor is a key offering in the Turntide electrification suite of powertrain products.
The 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, 30-40% greater torque, higher power density, and precise control. These motors are ideal replacements for radial flux motors in applications such as commercial vehicles, construction machinery, hybrid marine vessels, industrial robots, FC radiator fans, hydraulic pumps, and every place where 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 rotation axis. This design provides superior torque and power while using the same electrical components as radial flux motors. Additionally, due to their extremely low axial length-to-diameter ratio, axial flux motors are “flat” and have a smaller and lighter form factor than radial motors.
“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 game-changer 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, as we believe these will pave the way for a more sustainable future.”
Construction equipment is estimated to generate around 400 metric tons of CO2 emissions per year, representing roughly 1.1% of global emissions. Consequently, the decarbonization of non-road mobile machines is considered a key factor in efforts to limit global climate change. Additionally, electrified construction machines produce zero exhaust emissions, significantly lower noise levels, reduce energy costs, and enhance drive comfort making them more versatile to use indoors, underground, and in other locations with limited ventilation.
Since acquiring Avid Technologies in 2021, Turntide has been advancing the motor’s design, size, scalability, and production readiness. Leveraging digital twins and simulation software from Ansys, Turntide accelerated design cycles to ensure safety, reliability, long life, and full-power performance in the most rigorous and extreme conditions.
The motor features a patented composite rotor at its core. The rotor’s design makes it among the lightest and least inertial electric motors available while providing excellent stability with very little audible noise, vibration, or cogging torque during operation.
The motor is available in stack configurations from single to quadruple, from 100 kW to 880 kW peak power and 220 Nm to 2,400 Nm peak torque. With extensive system-level design expertise, Turntide also offers a range of matched inverters to streamline vehicle integration and shorten time to market.
