Laboratory for Electrical Machines, Drives and Regulations performs laboratory exercise from the following subjects:
• Electrical machines 
• Electromotor drives 
• Regulation of electromotor drives 
Laboratory for Electrical Machines, Drives and Regulations of electromotor drives is the part of the Faculty of Technical Sciences in Čačak. Exercises on programs of basic studies of Electro-Energy, Computer Engineering and Mechatronics and master studies of Remote Control are carried out in the Laboratory. Moodle system for e-learning with course materials is also available to students. In order to attend these courses, students need to send a request after which they receive the password to log in to the system.
