EVO Electric develops and manufactures advanced
electric machines, hybrid drive trains and generator
sets for a wide range of transportation and mobile
power applications
AFM-140 Axial Flux Motor
EVO Electric offers permanent magnet motors based on proprietary
axial ux technology that can be used in conjunction with custom built
or standard industrial inverters. AFM type electric motors combine high
performance with low weight and size, ideal for electric and hybrid
electric vehicles and a wide range of demanding industrial applications.
The AFM-140 motor range has the following key features:
• Very high torque and power density
• Low cogging torque
• Compact design with at front and back faces for mounting
• Integrated resolver for rotor position feedback
• Vibration tested to military standard
• Liquid cooling for enhanced performance
• Through shaft and customised versions available
