Axial Flux Motor Design Provides Increased Torque and Reduced Package Size
Replacing the cylinder and tube architecture of traditional electric motors with that of a disc for the rotor and stators offers performance and packaging improvements. by Sara Jensen

Daniel, co-owner and partner of Omni Powertrain Technologies. Omni, however, has developed an axial flux motor which it believes will provide benefits to a variety of industries, including the heavy-duty on- and off-highway equipment markets. In general, the axial flux design is torque dense whereas a radial flux motor is considered power dense, explains Craig Daniel. He says Omni believes its axial flux motor design can bring
some positive attributes to high-torque applications. “For the off-highway industry, we’re working to pair our motors with different types of drivetrains, swing drives or auxiliary drive applications because we can provide high torque at low speed very efficiently with the electric energy available.”
Why axial flux versus radial flux? Radial flux motor designs are comprised of two main elements, a rotor

he push toward electrification and other power alternatives has brought about several new technological developments in recent years. This is due not only to advancements in technology, but also evolving needs and application uses. Integral to many electric powertrains are the electric motors. While there are a variety of electric motor options currently in the market, the majority of the global market is composed of radial flux motor designs, says Craig
