SR Drives
A relatively new area for Darrah Electric Co. Switch Reluctance Drives is a growing market. With our ties
to other industries, we have developed a limited range of SR Drive Power Assemblies, both Water-Cooled and
Air-Cooled using various Semiconductor topologies.
Switch Reluctance Motors are used in applications that require High starting Torque, High speed and/or a wide
range of constant power.
Typical applications would be:
Current Designs
Water Cooled
- Using IGCT’s – 1.8MW – 2200VDC Link
Air Cooled
- Using IGBT’s – 1000kW – 650VDC Link
- Using IGBT’s – 300kW – 650VDC Link
