Axial flux motors, also known as pancake motors, are gaining popularity in various industries, including the electric motor space. These motors offer advantages over radial flux motors, such as higher torque and power density, as well as a smaller size. Infinitum, a company specializing in motor design, has developed a new axial flux motor called the Aircore EC motor. This motor features a lightweight printed circuit board (PCB) stator that is more reliable, efficient, and compact than traditional motors. The Aircore EC motor is designed for applications in commercial and industrial settings, particularly in HVAC systems. By using this motor, companies can reduce energy consumption, emissions, and waste. The combination of the motor and a variable frequency drive (VFD) allows for greater flexibility in operating points and can lead to cost savings in large facilities. Infinitum is initially targeting the HVAC market with its new motor, but the technology has potential applications in other industries as well. The global market for axial flux motors is projected to grow significantly in the coming years, driven by investments in product development. [Extracted from the article]
