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.
