Local invention and innovation were showcased June 13 at the Kress Motor showcase room located on West Main Street.
The company unveiled its newest developments to friends and members of the media, as well as discussed industrial and market applications for its newest development.
Kress Motors LLC has been in operation since November of 2009, and was founded by inventors Timm Vanderelli and his brother-in-law Rod Carter. The two have known one another since middle school and met in their school's electric shop class.
The product demonstrated was the company's axial flux motor. The motor is the only consumer grade modular motor that can be repaired on site, which saves expense and downtime. Such a feature can be vital in situations where repairs are needed at sewage treatment plants or if a hospital life-support machine fails. The motors can be used for everything from pace-makers to underground drilling machines and are especially suited for situations in which motors are needed to run around the clock.

Electric motors are used everywhere: in cars, in planes, in sewage pumping stations. But when the motors break down, they can take weeks to repair—a time frame that is problematic when the motors are handling essential tasks like pumping a town's water or keeping a person on life support.
Kress Motors LLC, a Ligonier company that was founded in 2009 by local attorney Lynda Dupre, thinks it has a solution.
The company's Axial Flux Motor is free of the complex electrical windings and magnets that make up traditional electric motors. As a result, the design is easier to repair: Rather than hauling a large, heavy broken motor out of a water pumping station and waiting weeks for it to be repaired, a mechanic could repair a similarly damaged Kress motor on-site in a matter of hours, said Brian Ott, the company's chief technical officer.
And the motor could continue to run even while a mechanic repairs its parts, Mr. Ott said.
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.”
