Design of permanent magnet synchronous motors
Bureš, Petr ; Cipín, Radoslav (referee) ; Vítek, Ondřej (advisor)
Given today’s trend with environment being very important, there has been an ongoing attempt in the rotating machine industry to create machines with highest efficiency possible. And so, permanent magnet synchronous machines represent types of machine with very high efficiency and are gradually replacing other machines in many applications. This work deals with familiarization of the properties of permanent magnet synchronous motor as well as typical design choices. The main focus of this work is the design of permanent magnet EC motor and following comparison of results obtained from analytical design and analysis in the RMxprt program. Finally, the results of design methods are compared.
Equipment for long-term test of BLDC controller
Řihák, Roman ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This diploma thesis deals with the design and realization of equipment for long-term testing of the controller of brushless DC motors. In the theoretical part are mentioned principles and explanation of the function of various types of electric motors. The diploma thesis also deals with brushless motors, how they are controlled, types, constructed, etc. At the end of the first chapter there is a mention of thermoelectric phenomena. The second chapter describes the appropriate design of equipment for long-term testing from the block diagram to the construction itself. The third chapter deals with the implementation and function of the entire test system.
Design of permanent magnet synchronous machine
Blaha, Jan ; Ondrůšek, Čestmír (referee) ; Vítek, Ondřej (advisor)
Nowadays in the area of drives, classical direct current machines are replaced for reason of low efficiency and low service life their frictional part by synchronous permanent magnet machines, among that belongs brushless or electronically commutated machines. This machines provide benefits of fine and effective regulation with no limits incurrenced by mechanical parts. Within this work, introduction with properties and construction of various types synchronous machines witch permanent magnets are performed, further the analytical calculation of design are made with effort to the best configuration for requisite characteristics. This design is compared with simulation made by computer technique and in the next step modifications of individual parts and choosen parameters for maximizing efficiency and minimizing volume are made. Comparison of success changes in design is made by simulation in program RMXprt again and the final machine is compared with original design, benefits of changes within efficiency and with considering of quantity used material are evaluated and his charakteristics are checked by Finite Element Method.
Sensorless control of BLDC motor
Križan, Jakub ; Toman, Jiří (referee) ; Grepl, Robert (advisor)
This thesis is focused on problematics of control of brushless DC motor in the sensor and also in the sensorless mode. Also it interprets possibilities of BLDC motor control with one faulty sensor and derivation and simulation of mathematical model. First part mentions options of rotor position sensing as well as existing methods of sensorless BLDC motor control. Second part describes control algorithms of sensor and sensorless motor control realised on device dSPACE and also realisation of faulty sensor control algorithm. Third part deals with derivation of mathematical model, its realisation using Matlab Simulink software and identification of its parameters. Last part concludes results and compares control methods used on the real system.
