Scalable Delivery Systems: Large Scale Material Handling Applications

Synergy is active in a wide range of industrial activities, providing end-to-end solutions in the following motion control applications:

  • Mills
  • Uphill, downhill, overland conveyors
  • Crushers
  • Fans
  • Variable speed pumps
  • Automatic load sharing (among multiple drives on a common system)
  • Conveyor spotting

Synergy Engineering Ltd. combines the tried, tested, and true resistive control technology with our expertise in detailed upfront engineering to create the best control of new and existing wound rotor induction motor applications, while using common, non-electronic components:

  • PLC of customer's choice
  • Special high-speed vacuum contactors
  • Cable
  • Synergy's proprietary stainless steel power resistors with welded connections
  • Interposing relays typically supplied for 4kV-18.8kV applications (400Hp and up), due to its unsurpassed reliability, the SRC has been requested for critical applications as low as 250Hp.

The intended application can be supplied. The SRC only requires a customer start signal interlocked with the primary starter.

The SRC is also available with continuous variable speed and torque control, or with a variable acceleration sequence.

The Secondary Resistive Controller (SRC) manipulates the wound rotor motor torque-slip characteristic to enable the delivery of the desired torque at the desired speed to control the speed and acceleration of a given load.

The SRC can be designed to accelerate a high inertia conveyor softly and smoothly over a few minutes or it can be designed to accelerate a crusher at the highest possible torque (breakdown torque of the motor) repeatedly.

Compared to alternate drive options, the SRC has the highest torque per unit of current for motor starting and controlled acceleration.
