High-Speed Switched

Reluctance Machines

Switched reluctance machines offer many advantages in high-speed rotating applications , particularly low-phase number and low pole number machines , such as the 4 / 2 machine .

Competitive Advantage

• Experts in high-speed , fault tolerant technology
• Knowledge of a broad range of prototyping capabilities , from sub-kW to 50kW
• Leading-edge tools for the analysis , design and fabrication of novel rotors using 3D printing

Impact

• The rotor is robust being a single stack of laminations that requires no windings or permanent magnets – allows the rotor to spin at high speeds
• Windings can be manufactured separately then mounted on the machine , which reduces size and cost
• The potential for very high-speed motors and generators up to 50,000 rpm
