Options for increasing the efficiency of small motors.
Kusý, Karel ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
This bachelor thesis concerns itself with the possibilities of achieving higher efficiency of small asynchronous motors and their manufacturing costs. The following chapters describe the design, function and principles of speed regulation of the asynchronous motor. Next, losses that occur during motor operation and ways of reducing them, are described. The last chapter of the thesis addreses factors that influence the manufacturing costs of the asynchornous motor and evaluates the material costs of one modified motor.

Losses analysis of small induction motors
Šišák, David ; Cipín, Radoslav (referee) ; Mach, Martin (advisor)
This bachelor thesis deals with analysis of losses of small induction motors. The first part of the project introduces the principle of operation and construction of induction motors. Furthermore, there is dealt with issuing each losses, their origin and disposition in induction motor. The project continues performing the analytical computation of the losses of induction motor with an output of 600 W. The losses of the motor are also calculated in the program Maxvell RMxprt. In the practical part, there are the results of the laboratory measurement on that motor and measurements concerning two another small induction motors different in nominal power. In the last part, there are compared the results of individual motor losses, obtained by computations and measuring. There are also compared the measuring results of losses of chosen motors depending on the nominal output.
