EMC Test laboratory for low voltage circuit breaker
Vejtasa, Leoš ; Dřínovský, Jiří (referee) ; Dohnal, Petr (advisor)
Nowadays there are electronic systems almost in every new device. They are emitting and receiving electromagnetic interferences. The safety levels for circuit breakers are also increasing. Because of these issues the circuit breakers must work properly also in areas filled by electromagnetic interference. This thesis describes the issues of electromagnetic susceptibility of the circuit breakers.
Automotive Electric Motors Innovation
Vejtasa, Leoš ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
There are a lot of electric motors for different applications in a car. Some of the cars contain over 50 electric motors. The majority has direct current motors. In this semestral thesis there are described all types of direct current motors used in the car and their applications in the car. You can also find here the ways of development of direct current motors in the near future. There is also an analysis of the issue of permanent magnets use in DC motors and their construction scheme.
