Synchronous Reluctance

Machines and Drives

Development of a new type of synchronous reluctance machine that has a skewed , axially-laminated rotor , which solves the problem of torque ripple typically associated with traditional rotors .

Competitive Advantage

• Innovative axially-laminated skewed rotor that improves machine performance and creates nearzero torque ripple
• Novel multi-phase winding techniques improve torque output
• Advanced tools for the analysis , design and fabrication of novel rotors using 3D printing
• Ability to produce smaller , cheaper machines
• Impact
• The rotor structure can be operated at very high-speed , making it useful in many emerging applications
• Synchronous reluctance machines and drivers are cheaper and more efficient than conventional field-excited and permanent-magnet synchronous machines , as they don ’ t require permanent-magnets , or rely on rotor currents
