Shushing electric motors

A UMR mechanical engineer and two of his colleagues have received a patent for a system that could improve the performance of electric motors.

Daniel Stutts, associate professor of mechanical and aerospace engineering, received a patent for a sensor and control system that can minimize the torque ripple that is found in many electric motors and generators.
“Torque ripple, a harmonic variation in motor output torque, contributes to vibration, noise and variation in the drive rotation of machines,” Stutts explains.
Stutts and his colleagues developed an inexpensive piezoelectric sensor to sense the reaction forces through its mounting hardware. “The sensor picks up the torque ripple with very high fidelity, enabling the signal to be used in a feedback control system to mitigate torque ripple,” Stutts adds. “We think it is a competitive option for reducing torque ripple.”
Stutts’ co-inventors are Jason Neely of Sandia National Laboratories in Albuquerque, N.M., and Steven Pekarek of Purdue University.

Making tornado alley safer

Growing up in northeast China, Guirong “Grace” Yan didn’t see many tornados in a country where the number of documented twisters is a fraction of those that hit the United States. But as her academic career took Yan to several postdoctoral fellowships and then faculty positions in Indiana, Missouri and Texas, the assistant professor of […]
