Project: Integrated starter-generator and torque amplifier
Pioneering research on the project "Integrated starter-generator and amplifier torque" dates back to 2002. The research was conducted in collaboration with AET d.o.o. from Tolmin, supported by the Ministry of Economy, Slovenia. The basic idea was the integration of existing systems for start-up and generation of electricity at road motorcycles (which is most often carried out with two electric machines) into one electric machine. At the effective management of the new machine new functionality can be added to basic; such as: increase in the total torque on the main motor shaft, reducing ripple torque of internal combustion engine, reducing emissions of harmful exhaust gases and some interesting and useful features for driver comfort. Practical implementation of ideas includes plenty of knowledge in the areas of design of electrical machines using modern magnetic materials, power electronics and electromotor drives. The so-called hybrid soft aggregate act as an integrated starter-generator based on a brushless DC machine with permanent magnets on the rotor. Machine can work in the motor and generator mode and serves as a starting motor, generator and additional power plant, which operates in parallel with an internal combustion engine. A prerequisite for the operation and implementation of all these features, is the control-regulation electronic circuit, which should ensure an appropriate supply conditions for brushless machine to guide the three-phase AC induced voltage, adjust the voltage levels of battery power (12 V) and dc-link voltage and enable two-way flow of electricity. In 2004, prototyping product was successfully attached to a motorcycle on Tomos Revival, presented at the international motorcycle exhibition in Munich INTERMOT. For some of the design solution and development the product's development team was awarded by the Chamber of Commerce Office for Innovation in 2003. Contact: prof. dr.
