AC Kinetics to showcase next-generation motor control software at ARPA-E Summit; 10-40% reduction in energy consumption and improved performance
Motor control company AC Kinetics, Inc. will introduce its next-generation motor control technology at the upcoming ARPA-E Energy Innovation Summit in Washington, D.C., 25-27 February. AC Kinetics was selected as a Semi-Finalist in the Future Energy Pitching Event at the Summit.
The advanced AC Kinetics software (ACKS), supported by real-time adaptive algorithms, runs on standard drive hardware for motorized equipment in the consumer, industrial, and transportation markets. The drive software controls the motor to optimally generate torque on demand in a maximally efficient manner.
Using its nonlinear optimization algorithms, the drive software automatically configures itself to a particular motor and application, eliminating the suboptimal performance and energy usage associated with hand tuning. Motor energy consumption is minimized for the same work output at all operating points, while dynamic performance is increased, the company says.
By optimizing the nonlinear dynamics of the motor, ACKS achieves high energy savings while improving both transient performance and disturbance rejection. Compared to several well-recognized drive brands, the ACKS solution uses up to 50% less energy during transients and 10% less energy in the steady state, while tracking references more precisely and being superior in rejecting disturbances, the company says.
The AC Kinetics drive algorithms can be integrated seamlessly with AC drive products currently available from major manufacturers.
We have developed several algorithms for electric motor control that reduce energy consumption by 10% to 40%, while simultaneously improving motor performance. Our technology also enables motors to run cooler, and therefore last longer.
Electric motors consume 45% of all electric energy produced globally, and two-thirds of the energy consumed for industrial production. AC Kinetics technology can substantially reduce the world’s electric bill—the global spend is US$570 billion annually—while cutting the carbon pollution generated by power plants.—Dr. Neil Singer, president of AC Kinetics, Inc.
The AC Kinetics team’s first motor control technology, invented by Dr. Singer and patented by MIT, reduces vibrations and acoustics on hundreds of millions of machines world-wide. This next generation motor control is compatible with existing AC induction motor drive hardware and is now available for licensing.
An independent motor drive efficiency study at MIT’s Laboratory for Manufacturing and Productivity (LMP) compared a hardware implementation of the AC Kinetics controller against some of the world’s leading motor drives. The AC Kinetics motor control solution outperformed the other motor drives while using significantly less energy. The testing was completed and published by MIT in May 2012.
The AC Kinetics, Inc. team has worked together for more than 25 years, and its members jointly and independently commercialized new technologies for the last 35 years. In the 1990s, the team invented and commercialized algorithms that reduce residual vibrations, improve settle times, and minimize unwanted acoustics in motorized machines. Those algorithms now control hundreds of millions of machines worldwide ranging from computer disk drives to cranes handling radioactive materials operated by the Department of Energy and private utility companies.
The AC Kinetics team also developed a novel algorithm for control of parallel motor gantry machines. The technology was licensed exclusively to Dover Motion Division of Danaher Corporation to dominate the precision gantry machine market.
