Traction inverter for an electric bike
Prudík, Martin ; Klíma, Bohumil (referee) ; Vorel, Pavel (advisor)
A drive design for an electric bike with brushed DC disk motor is proposed in this thesis. Especially the design of a DC/DC converter with DSC control is described. The converter can operate as step-down and step-up too. Minimum dimensions and sufficient power for riding without human assistance were the main demands on the design.

Calculation of the optimum slip frequency with respect to the minimum losses of an induction motor
Prudík, Martin ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
A mathematical model describing the calculation of the optimal slip frequency of an Induction Motor with squirrel-cage is proposed in this work. The derivation is done using a replace -network, and is designed for a wide range of speeds and torque. The requested torque, speed and constants of replacement network are the inputs of the optimization. Optimum slip frequency and corresponding line voltage are the outputs of this optimization. The results of the calcullations are presented using two asynchronous machines for different speed and torque.

Rotation speed sensor
Dudáš, Juraj ; Knobloch, Jan (referee) ; Prudík, Martin (advisor)
This bachelor thesis is aimed on rotation and position sensing of rotating devices topic. The thesis is devided into theoretical and practical part. The first theoretical part deals with rotation and position sensing, sensing possibilities and types of rotation and position sensors. The next thing in this part is about market possibilities and research in sphere of these sensors. In the practical part of the thesis is realized the rotation and position sensor. In the introduction of this part are defined the main parts, which are going to be used in this device. Afterward are these parts used in the scheme of wiring diagram and printed circuit board. Next in the thesis is described the manufacturing of the device it’s programming and functioning. The practical part ends with the test of the device. In the conclusion are the process of the thesis and reached results evaluated
