Starting device is used for contact-free smooth starting of asynchronous motors with a phase-wound rotor in various applications:                                                                         

  • belt conveyers in mining plants and power stations
  • transporting conveyers of granular products
  • slow start of pumps
  • slow start of different lifting devices
  • slow start of mills and crushers

Main advantages:                                                                             

  • smooth non-skidding movement of the conveyer belt upon system start by changing motor torque zero to the break-away momentum and maintaining a certain level of torque throughout acceleration                                                           
  • possibility to run the conveyer at low speed needed for the initial loading and for maintenance procedures
  • starter supports parallel running of motors of different makes
  • high reliability in all climatic conditions
  • safe starting of the conveyer after an emergency stop avoiding rollback in the case of an inclined positioning
