Small satellites are nowadays at least often equipped by large number of sensors for attitude determination. Due to small budget, which is quite often in small satellite project, it is necessary to use cheap sensors, that are not designed for space applications. There is no&#x...

This paper describes development of stationary bike, which is able to produce and store electrical energy. Device consist of BLDC motor, used as generator, connected to stationary bike and power electronics managing the flow of the energy. Electrical energy from the generator can b...

This work deals with thermal design of permanent magnet synchronous motor (PMSM). The designed motor is the in-wheel traction motor for automotive application. The motor consists of an external rotor and inner stator with water cooling system. The thermal calculation is based on th...

This paper deals with possibilities of measuring resonance frequency of absorbing elements using the loudspeaker. Commonly used methods for determine absorbtion coefficient α are not suitable for prototypes design. For verification in the reverberation chamber a large sample area is required....
