Tiivistelmä
The purpose of this thesis was selecting the main drive system for the testing phase of the i-Locker. Different electric motors were studied and compared to see the benefits of each motor in combination with a frequency drive. The best suitable electric motor and frequency drive were selected to be used for the i-Locker application.
The main function of the drive system is to rotate the lockers mounted onto the i-Locker’s frame. The electric motor converts the electrical energy into mechanical energy. This energy is transferred from the shaft of the servo motor to the lockers by using a transmission existing out of a drive gear, a driven gear, and an ANSI 50 chain. The driven gear and lower gear are both mounted onto the same axle, the lower gear is connected to an upper gear with an ANSI 50 chain. On this particular chain the lockers are mounted.
For choosing the most suitable electric motor and drive the theoretical background will be used for the needed information. Calculations are made and data is gathered from the i-Locker application at TAMK’s Laboratories. The speed, power, and torque calculations were needed for selecting an electric motor. The data received from the calculations determines the size and type of the electric motor.
The biggest disadvantage of the AC variable frequency drive was the possibility that harmonics could occur if the AC variable frequency drive wasn’t installed correctly. Therefore the installation and connections of the variable frequency drive should be taken very serious. This Thesis greatly explains and illustrates the physical connections as well as the software installation, to negate the disadvantage.
The best suitable main drive system for the i-Locker application was the brushless AC servo motor from Control Techniques and the Unidrive M700 from EMERSON Industrial Automation. There was a perfect communication and efficiency between the two components.
