SINGLE-WHEEL DRIVE SYSTEM FOR ELECTRIC QUAD
GIGATRONIC is your development and consulting partner, specialised in electronics and information technology. In 2012, GIGATRONIK built an ATV quad with electric single-wheel drive. This vehicle with a maximum speed of 50 km/h served as a test vehicle and training object for employees and students. The project is the result of the further development of the popular ELMOTO e-bike, for which GIGATRONIK developed the motor controller in 2009. This controller, in a new upgraded version, is mounted four times in the e-quad. Belt drives specifically designed for this project transmit the 5 kW from each BLDC motor independently to each of the four axles. The modern lithium-ion battery system guarantees a range of currently 40 kilometres. A central control unit from our GIGATRONIK Tool Suite coordinates drive and vehicle management. Traction components and controllers are connected via CAN and LIN. Refi tting with an electric drive was realised with almost no weight change. Only minimal modifi cations to the frame are required for this 300 kg vehicle to receive road service approval. Design and development were prototyped using state-of-the-art automotive industry methods, processes and development tools. GIGATRONIK is currently simulating drive dynamic functions of the e-quad - such as torque vectoring, ASR and recuperation - using CarMaker© from IPG Automotive GmbH, where they will be virtually tested and verified.
