Drive model for EC motor elevator analysis
Javořík, Zdeněk ; Koláčný, Josef (referee) ; Vondruš, Jiří (advisor)
The master thesis encompasses the possibilities of position evaluation and drive control with the aid of SMI work enviroment. Furthermore the thesis is directed to create a program through a designed control algorithm. The work is realised on the elevator model with electronically commuted motor. An incremental scanner is used as the position sensor. The motor control unit is set up and programmed in the SmartMotorInterface software. In the next part, measurements with altered parameters are conducted. On the basis of these measurements the influence of parameters on the positioning process and its accuracy is evaluated. At the conclusion of the work, a design of laboratory task for educational purposes is created. The laboratory task is composed in such a way, that students would become familiar with the SMI work enviroment and would be able to practicaly test the setup of incremental position sensor and motor control with the aid of entered algorithm.

Project of service lift
Kryška, Martin ; Malach, František (referee) ; Malášek, Jiří (advisor)
The aim of the diploma thesis was the conceptual design of a service lift driven by the rigid chain. The introduction part focuses on a general description of lifts and existing issues. The following chapters contain the created lift design, construction of important design elements and functional calculations. In the conclusion, evaluation compared with hydraulic lifts and evaluation of speed of the lift, starting and braking to exact stop are performed.

Design of elevator for pallets
Hájek, Lukáš ; Winkler, Tomáš (referee) ; Škopán, Miroslav (advisor)
The diploma thesis is focused on the construction design of elevator for pallets with car seats weighing 200 kg. This device is proposed for vertical transport of the load between two working positions which are separated by 6m. Part of the pallet hoist is a roller conveyor attached on a lifting frame. The roller conveyor allows loading and unloading pallets from the fixed roller conveyors in the lower and upper station. There are the functional calculations of important parts, strength control of traction belt and shaft of driving pulley drum. By FEM (Finite Element Method) is detected stress distribution of the lifting frame. Parts of the annex are the manufacturing drawings of the lifting frame, shaft of driving drum, the driving station and drawing of the whole assembly vertical conveyor. Furthermore, the timing diagram function for one cycle, risk analysis and FMEA.
