SRC
An engineered product, the Secondary Resistive Controller
is used for accelerating
Wound Rotor Induction Motors for all types of applications.
Essentially, the SRC controls the motor speed or torque through
the
programmed selection of binary-coded stainless steel resistors
in the rotor
circuit.
Ideally suited for replacing existing outdated resistive
controllers, and for new materials handling systems which
require:
- controlled acceleration
- limited inrush current
- the highest reliability attainable
Requiring little to no maintenance over its 20+ year technological
life, the SRC is an obvious drive choice for applications in the
most remote locations, and the harshest operating environments.

Pump
SRC
Synergy has applied its proven Secondary Resistive Controller technology
with pumping applications to create a new Pump Drive SRC with variable
speed capability.
By combining Synergy's SRC technology with our new theories
and extensive engineering design, we have implemented the Pump
Drive SRC to be one of the most reliable systems on the market
with zero failures to date.
Each Pump Drive SRC is designed specifically to meet the requirements
for each situation.
This includes application-specific speed control and acceleration
programs, as well as application-specific specially designed dual-purpose
stainless steel resistor grids used for acceleration and continuous
speed control.
This is a fully self-contained and compact unit that can be easily
integrated into an existing system or used as a stand-alone unit.
Benefits include:
- Reliability
- Efficiency
- Cost
- No harmonic generation
- Due to the compact design, installation time is minimized.
The ability of the Pump Drive SRC to deliver up to breakdown
torque to the driven load as required while still providing
variable speed,
makes the Pump Drive SRC a most effective drive.
Overall, the Pump Drive SRC proves to be less costly than other
pump drive options.

Lauhoff—Saving Energy
Controlling belt speed does not significantly reduce energy
costs, as presented in a recent technical paper by Hans Lauhoff: "The
energy consumption of long, horizontal belt conveyor systems
in stationary operating conditions is determined by the motion
resistance."

Instrumentation & Control
The Gibraltar mine was reopening after a long shutdown. They
needed to revamp their entire control system, and called upon
Synergy Engineering for expertise
in instrumentation and control…

Electrical
When the new Minera Antamina copper mine was constructed high in the Andes
Mountains of Peru, a new port facility was needed to process the concentrate
and transfer it to deep-sea vessels. Synergy was asked to design the electrical
system for 1600 tph shiploader at Puerto Huarmey…

Design Fundamentals for Drive Systems on Conveyors
By Luke Meakin and Peter Saxby, Hatch
The combination of a number of factors can result in conveyor drives being undersized or operating in an unsuitable manner. Some of these factors include:
- The trend to reduce drive sizes by reducing friction coefficients.
- The trend towards using squirrel cage induction motors under variable voltage variable frequency controls combined without considering the drive characteristics.

The Right Drive to Maximize Efficiency and Production for Large Overland Conveyors
By Nicole Hampton, P.Eng, Synergy Engineering Ltd.
This paper examines various drive systems available for large overland conveyors, with special attention to starting and operating methods with respect to two most commonplace drives, the
VFD (for squirrel cage induction motors) and the SRC, secondary resistive controller, (for wound
rotor induction motors).
