Development of system for control of reversible electric drive friction-plate electromagnetic clutch

The paper proposes a new method of control of the friction-plate electromagnetic clutch, which improves its operation properties and reliability. Draft force generated by the clutch permanent magnet is additionally increased with electromagnet flux on the interval of start and reverse of electric drive under load. A wiring diagram of the reversible electric drive with normally closed polarized electromagnetic clutch is provided. The authors present results of designing a microprocessor diagram for control of the reversible asynchronous electric drive equipped with the clutch of this type. They offer a flow chart of the controller program and developed program for generation of control signals supplied by the controller for asynchronous electric drive with the friction-plate electromagnetic clutch.
