Electric motor technology can replace hydraulic and pneumatic starter systems for gas turbines and industrial turbines, reducing the need for hydraulic infrastructure. Oil leakage from hydraulic systems causes environmental and safety issues. Electric starter motors are lighter, smaller, and produce more torque than hydraulic starters. Parker offers turnkey electric starter motor and drive systems that meet turbine start requirements. These systems use compact induction or permanent magnet motors cooled by air or liquid. The transition to more electric starters represents progress toward oil-less turbine engines.

• Background
• Motor Technology
• Drive Technology
• Conclusion
• Other Components of the Oil-less Engine

3. Abstract:
Oil-less technology
“Electric motor technology can be used to
replace new and existing hydraulic and
pneumatic starter systems, reducing the
need for hydraulic and pneumatic
infrastructure.”

4. Background:
Oil Leakage and Mists Hazards
Wider industrial trend away from using high pressure oil:
• Pollution: Oil leakage and mist are environmental
pollutants
• Insurance Cost: Oil leaks are a fire hazard and can
increase the cost of insurance
• Health & Safety: Oil mist can reduce lung capacity,
cause respiratory disease, and reduce overall worker
productivity
• Disposal: New European proposals for waste oil, added
under the European Liability Directive (ELD)
“Environmental Damage protection” regulations, are
increasing oil disposal costs
• Legislation: Oil mist safety is managed in ISO14001

5. Background:
Application 1: Aero-derivative Turbines (<70MW)
• Gas Turbine
• Lightweight (banana)
Gearbox
• Starter Location
• Key requirements:
Weight & Moment
asserted on gearbox

6. Background
Application 2: Industrial Turbines (<70MW)
Key Requirements:
Space Envelope relative to the Hydraulic Start System
Minimum change from Hydraulic
