Properties of whiper motor
Kůta, Aleš ; Skalka, Miroslav (referee) ; Janda, Marcel (advisor)
Nowadays a need of numerical computations of different tasks in the area of electrical engeneering is still rising. Common denominator of great demands given on a constructor and ecomonization of manifacturing is a requirement of efficiency. It´s necessary to use a characterictics of construction, own fundamentals and unique attributes of product. Application of Finite Element Method is possible solution which accombines abilities and knowledge of user in consecutive to complexity of computatio. This enables a use of the most optimal solution. This thesis describes a principals of Direct-Current motor and its´ special design: Direct Inductor motor with extrinsic excitation (permanent magnests). It presents a operation of wiper motor in consecutive to wiping systém and fulfillment of engeneering standards. It also describes a principles of Finite Element Method in context to basics of simulation program FEMM. Main attention is given to creation of concrete model and to simulation of gauged exercise with wiper motor. Also there is a second simulation of motor, focused to different type of stator excitation. Findings of thesis is a comparation of theese exercises. Consecution of modeling in software environment is described. It compiles gauged excercise and interprets them.

Measurement of DC and EC motors characteristics
Chlebný, Radek ; Cipín, Radoslav (referee) ; Vondruš, Jiří (advisor)
The Bachelor thesis deals with commutator direct current motors and electronically commutated motors of company Maxon motor AG. The first part of its deals basic structural elements and focuses on the characteristics of these engines, such as lifetime, revolution properties, efficiency and control methods. The thesis deals with properties, principle of operation and construction of hysteresis brake. Another important theme is improved by the construction of the dynamometer. The last part contains the actual measurement of DC commutator motors assigned Maxon RE and Maxon S, which are loaded with hysteresis brake and final evaluation measurements comparing measured values with the data producer.

Design and realization of the DC motor controller for mobile robot
Hrbáček, Jan ; Singule, Vladislav (referee) ; Krejsa, Jiří (advisor)
The goal of the bachelor's thesis is to design a bidirectional electronic speed controller for a brushed DC motor with the power up to 250 W. The background research part introduces various ways of each subsystem's implementation and selects proper technologies to be used to build the controller according to the specification. The description of all important design details, developed firmware functionality as well as design of the prototype and the end product is mentioned in the thesis' part concerning construction. The final controller was successfully tested equipped in the wheeled robot Bender 2. It has been found fully functional and reliable in all operating conditions.
