Liquid Resistance Starter (LRS) Systems

Boltech Automation delivers high-efficiency Liquid Resistance Starters (LRS) precisely engineered for large slip ring induction motors. By dynamically varying electrolyte resistivity during acceleration, our LRS configurations provide optimized torque profiles while cutting high electrical inrush current. This minimizes transient torque stress across critical gearboxes and machinery components in heavy industrial load applications.

  • Smooth and controlled motor starting
  • Reduces high starting current
  • Provides high starting torque for slip ring motors
  • Minimizes mechanical stress on motors and driven equipment
  • Improves motor life and operational reliability
  • Adjustable starting current and acceleration time
  • Suitable for heavy-duty and high-inertia loads
  • Low maintenance and robust construction
  • Reliable performance in harsh industrial environments
  • Designed as per IEC/IS standards
