710587High Efficiency Geared Wheel Hub MotorClosedGRD Proof of ConceptInnovate UKCompactCaddy Ltd are world leaders in the design and manufacture of fractional horsepower, axial flux electric DC motors. These motors are not only highly energy efficient, but also have a high torque output and are very quiet in use. The aim of this project is to build a series of bench top prototypes to prove the suitability of this technology for the electric bicycle market. To achieve this we will have to redesign the motor layout, integrate a gearbox and enable the unit to free wheel. These bench top prototypes will also enable us to carry out the necessary motor testing to predict the likely motor characteristics and resolve design issues. From the results of our earlier SMART Proof of Market project we know that our motor would be a very attractive proposition to end users and have identified several routes to market. Note: In an axial flux motor the magnetic flux field is orientated parallel to the motor shaft, whereas in a radial flux motor the field is perpendicular to the shaft.
