This training program is suitable for beginners and advanced students. The first two chapters address the topic of controlling DC and AC motors. The third chapter focuses on the energy efficiency of electric drives, looking at economic and environmental aspects. Electric drives 2 Electric drives 1 The “Electric drives 1” interactive multimedia training program provides an engaging introduction to the world of electric motors. The first section sets out the basic principles of electric drives. The second section illustrates the construction and functioning of DC motors, while the third section deals with the special features of AC motors. From the table of contents: – Basic principles of electric drives – Familiarization with different motor types (stepper motor, asynchronous motor, universal motor) – Mechanical principles (conversion of mechanical/electrical energy, motor - generator, circuit diagram and current direction, transmission variables (force, mechanical power, efficiency etc.), definitions of torque and speed) – Electronic principles (basic principle of the motor, Lorentz force using the example of a conduction loop, electrical and magnetic fields, occurrence of torque, righthand rule) – Familiarization with different DC motors – General (functional principles, commutation, technical data, brushless DC motor, load dependency, difference between series and parallel connection) – Parallel connection behaviour – AC motors – Difference in power supply (DC, AC, three-phase AC) – Familiarization with different AC motors – General functional principle (difference between synchronous and asynchronous motor), technical data, rating plate, characteristic curves and their interpretation, definition of reactive, apparent, and effective power) – Single-phase AC motor – Three-phase AC motor – Stepper motors – Summary and review exercises Single use via Festo LX Order no. 8147890 Licenses via Classroom Manager VT Order no. 8038125 Digital learning > eLearning Courses – Differences between DIN standards, VDE regulations and DIN-VDE standards, statutory requirements, and legal consequences. – Definition and overview of protective measures to prevent direct contact – Protection by insulating active components – Protection by covering or cladding – Protection by barriers – Protection by distance – Definition and overview of protective measures to prevent indirect contact – Production by disconnecting power supply – Mains systems (TN, TT, IT systems) – Protection by disconnection – Testing protective measures – Measurement and measuring devices – Safety and assistance – Summary and questions to check understanding Single use via Festo LX Order no. 8147893 Licenses via Classroom Manager VT Order no. 8038116 This interactive multimedia training program provides an introduction to the complex topic of protective measures. It explains what electrical protective measures are and how they are classified. Trainees will also become familiar with all the legal regulations in this area. The measures that are effective in preventing direct and indirect contact are outlined using various specific examples and functional principles. Finally, there is an explanation of how protective measures are tested and what actions should be taken in case of an accident involving electricity. From the table of contents: – The dangers of electricity – Humans and electricity – Electric shock hazards – What are electrical protective measures and how are they classified? – Protection levels – Protective measures, protection classes Electrical protective measures From the table of contents: – The function of actuators in mechatronic systems – Electric motors – DC motor – Torque and current – Behavior of DC motors – Induced voltage and speed control – Characteristic torque/speed curve – Working with data sheets – Determining the transmission ratio Single use via Festo LX Order no. 8147892 Licenses via Classroom Manager VT Order no. 8038124 Using the everyday example of a car park access control system, the trainee learns the basics of a mechatronic system. Building on this, the training program determines what function the actuators have in the controller. A DC motor is then studied in more detail as an example of a typical actuator, e.g., its structure and the laws which govern its operation. Further chapters cover speed control and the use of data sheets, as well as the transmission ratios which can be achieved by using a gearbox. Actuators – DC motor
