Frequency converter for self-propelled freight wagon

photo_fc_mining_industry This is a symmetrical transistor frequency converter with an intermediate DC link.

Main functions:

  • Smooth acceleration and braking, change of direction;
  • Individual control of each drive of the in-wheel motor;
  • Anti-skid and anti-slip protection;
  • Braking energy recuperation to the supply network (when wagon is moving downhill);
  • Emergency stop in case of loss of supply voltage;
  • Protection and diagnostics of internal assemblies of the motor.

Application:

  • Converter can be used for power supply of asynchronous traction motors of self-propelled trolleys, wagon pushers and other electric vehicles.
