WHAT WE DO: Drives

The Secondary Resistive Controller is a combination of hardware and software that controls the speed of the wound rotor motor and its torque characteristics.

Synergy engineers drive systems for large industrial applications:

Wound rotor motor secondary resistance control
  • Conveyors
  • Crushers
  • Mills
  • Pumps
  • Cycloconverter:
    • Mill inching drives
    • Conveyor creep drives

Cycloconverters eliminate the need for external switching to control the magnetic field as a current’s polarity changes.

Commonly used for low-speed reversible high-power motor drives, cycloconverters generate inter-harmonic currents to reduce network disturbances and voltage distortion.

Applications for cycloconverters include steel rolling mills, rock crushers, and conveyors for material handling.
