High Power Starter / Generator for Harsh Environments
DEMONSTRATING EXPERTISE AND CAPABILITY
Denis Ferranti Group has developed high-power starter / motor / generators for hybrid applications.
Requirements
Nominal mechanical power 12kW to 50kW
Voltage Low V, current > 1,000 amps
Short bursts of operations
Efficiency > 95 percent
Forced air cooling
No re or motor burst
Least mass
To answer this requirement Denis Ferranti Group developed a machine with the following features:
Electric Machine
Permanent magnet electric machine with optimised geometry, slot fill and materials
High temperature components
Optimised for increased slot fill and low ac losses
Mass of 8.7kg
High availability and re criteria
The programme followed a typical aerospace research development route and was subsequently tested on Denis Ferranti’s site and at the customer’s facilities on the intended gas turbine.
