YASA has built on the work undertaken by founder Dr Tim Woolmer during his DPhil at Oxford University and now has numerous patents and patent applications covering the key subsystems (rotors and stator) of its unique axial flux "pancake style" motor. The patents cover the critical aspects of axial flux motor manufacture as well as design and include thermal, structural, magnetic and manufacturing techniques.
The Yokeless And Segmented Armature topology has enabled YASA to develop simplified motor manufacturing techniques that are very repeatable and cost-effective. The manufacturing method is highly scalable and suited to all levels of customer demand from small batches through to serial production.
Manufacturing takes place in YASA's own ISO9001:2008 accredited facilities.
The YASA 750, YASA P400 Series and YASA 400 axial flux motors achieve power densities of up to 10kW/kg and torque densities which are significantly better than the nearest competitive motor topology. High power densities are achieved at relatively low speeds (2000-9000rpm) which make the motor ideally suited for hybrid and generation markets.
These bespoke dynamometers are run with in-house developed software enabling a wide range of thermal and performance tests to be undertaken. A wide range of customer drive cycles can be tested with high dynamic and continuous loads. Please contact YASA for further information.
