  2. Content • Fundamentaldefinitions • DC engines • AC engines • Asynchronous engines • Synchronous engines • Step-by-step engines • AC converter-fed engines • Concluion

  3. What the electromagnetic drive is? Electromechanical device intended for electrification and automation of working processes and consisting of converters, electromagnetic engines, transfer and operating devices is called an electromagnetic drive.

  4. Electromagnetic drives Types of electromagnetic drives: • Group • Single • Multiimpellent

  5. Group drives

  6. Drives characteristics Group: • low EFFICIENCY; • irrational use of premises; • high traumatism.

  7. Single drives

  8. Drives characteristics Single: • too high capacity of the engine that’s it has low EFFICIENCY; • complex kinematics of the machine tool; • installation of connecting couplings is required.

  9. Multiimpellent drives

  10. Drives characteristics Multiipellent: • has elementary kinematic circuits; • the engine is built in directly into the working body; • the maximal EFFICIENCY; • has conditions for independent optimum control of the working body.
