Transverse flux technology
http://etmpower.com/technology/
"Key Technology Attributes ETM motors are based on transverse flux technology, which until now largely existed in only in some narrow markets. ETM believes it is among the first companies to capture the benefits of transverse flux in manufacturable, cost competitive designs using common motor materials and standard manufacturing processes. ETM motors are distinctly different than conventional motors in that TFM uses simple toroidal coils with the stator 'wrapped' around the coil while conventional motors usually require copper coils that encircle individual stator teeth. Conventional windings suffer from poor slot fill and end turn inefficiencies that become worse as pole count increases. By using a single toroidal coil per phase, ETM motors enable high pole counts with very low winding resistance. This results in motors that produce unusually high continuous torque per size and weight, while matching or exceeding industry leading peak torque output. This allows for longer duty cycles, increased efficiency, excellent thermal properties, and, where current systems require outsized conventional motors, increased cost savings resulting from our ability to provide matching torque requirements in a much smaller motor mass. ETM motor designs are inherently scalable from fractional HP to over 100HP and are ideally suited for applications where high continuous torque density, direct drive, reduced thermal load and increased efficiency are desired." |

Transverse flux technology
http://etmpower.com/our-motors/500w-...t-drive-motor/
"500W e-Bike Direct Drive Motor Transverse flux motors from Electric Torque Machines (ETM) provide direct drive solutions for demanding applications. ETM's e-bike hub motors offer smooth, strong, efficient hill climbing and acceleration in a small package. Features and Benefits ETM proprietary transverse flux motors provide a 3X continuous torque advantage over conventional motors: Best-in-class hill climbing and efficiency Compact size Quiet direct drive smoothness and reliability Disk brake compatible Optional 9/10 speed cassette or freewheel Optional 10mm flatted or 12mm through axle Power and speed range configurable for EU and US applications" |
