Different types of axial-flux permanent magnet electromagnetic μ-generators have been developed in LEG in collaboration with Laboratoire d’Electronique de Technologie de l’Information (LETI), CEA Grenoble. A Ø8 mm planar generator consists of a permanent magnet disc rotor cut out of bulk SmCo5 or NdFeB, and a silicon stator with electroplated three-phase planar coils. High speed electrical tests exhibit an output power of 5 W per stator at 380 000 rpm. A first prototype of integrated μ-turbo-generator driven by compressed air delivering an electric output power of 14.6 mW at 58 000 rpm is also presented. Possible applications of the μ-generators range from high speed μ-gas engines for the generation of electrical power at the Watt level, to autonomous low-power μ-systems for wireless flow or air-speed sensing.
