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.
