New Kress motor eliminates heavy back-iron with independently controlled stators for high-reliability, high efficiencies in electrical motor applications.
Ligonier, Pennsylvania, June 27, 2013 – Kress Motors LLC is giving demonstrations of a prototype electric motor that eliminates the requirement for an expensive rare-earth based magnet array and the heavy iron yoke structure that is required for traditional Switched-DC electric motors. This new design uses technology invented by Timm Vanderelli and Rodney Carter, and is protected by a newly-granted U.S. patent and two additional patents that are currently pending. This revolutionary motor design delivers dramatic commercial benefits by: • Reduces weight through a simpler design with no back-iron • Reduces electrical consumption and repair downtime for lower life cycle costs • Improving the ability to control and monitor motor performance “This new motor design will deliver efficiencies of over 92%," stated John Kimball, President of Kress Motors LLC at the demonstration session held at Kress Motors headquarters in Ligonier, PA. He added: “The new design delivers far greater operational reliability because the motor continues to rotate even if one or more of the easily-removable field windings fail. This is in contrast to the complete rotational failure of traditional AC or DC motors due to winding failures. Winding failures in traditional AC or DC motors often result in a two to three week off-line repair period for these conventional electric motors.” |
