Drives:
VFD and DC Drives
Secondary Resistive Controllers are an area of extreme specialization
for Synergy. In fact, we probably do it better than anybody
else. But that doesn't mean we recommend SRC for every
application.
At Synergy, our expertise includes variable frequency drives and
DC drives. We understand the pros and cons of each. It's
our task to engineer unique drive systems by analyzing the geographic
imperatives of climate and terrain and operational objectives of
the project. We match the right solution to each individual problem.
VFD:
Wide range speed control 0-100%
Continuous speed control
Regenerative
Limited current inrush
Technology is constantly improving
Apron feeders, variable speed conveyors, variable speed pumps
Trade-offs:
- $/Hp Harmonics generation
- Limited torque
- Technologically complex
- Motor heating
- Limited starts/hour
- Load sharing
- Controlled environment installation
DC Drive:
Torque output increases as speed decreases
Ideal for crushing applications
Requires a DC source
