Small Induction Motors
Chvatík, Štěpán ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
This bachelor‘s thesis deals with a single-phase induction motor and is organized in five sections. In the introduction is briefly described its construction and compared with three-phase induction motor. The first chapter describes the emergence of a rotating magnetic field of motor, methods of obtaining the starting torque, the influence on properties of different types of motors, comparing the torque characteristics of the different types of motors. In the second chapter is discussed permanent-split capacitor induction motor, its calculation and operational optimization. The third chapter deals with the determination of general principles of calculation and calculation method of single-phase induction motor with auxiliary winding. The fourth part verified the accuracy of these procedures on the selected motor when we performed calculations based on the input parameters of the motor, and after that these calculations are compared with the output parameters which are prescribed by the manufacturer. Verification of the relevance of declared parameters is supported by measurements on the mentioned device and their evaluation.
