Excitation Systems

Based on almost a quarter century of experience with the design of rotating electric machinery, EME has a solution for your brushless, static, or DC generator excitation system. Whether converting from brushless/DC to static excitation or upgrading a current system, EME provides economical and reliable alternatives to OEM products and services.

Collector Assemblies

EME offers semi-custom design of each unit to fit the needs of the customers’ application and utilize existing equipment such as bearings, housing, shafts, etc.


  • Fast response time to changing load demands.
  • Reliability – no forced outages due to damaged diodes and fuses.
  • No rotating electrical components – All power transmission components are stationary and not subject to the high forces associated with rotation.
  • Minimal maintenance – only brush changing and filter replacement, which can be done safely while the unit is online.
  • Minimal outage time for installation.

Brushless Exciters

From complete custom assemblies to upgrades and service on existing units, EME has the capability to serve your Brushless Exciter needs.


  • No brushes to service.
  • No external power supply required with use of a PMG.
  • Minimal maintenance – only yearly inspection is needed to verify winding and diode wheel component condition.
  • Minimal outage time for installation.

DC Generator Exciters
