Hear it from our customers! Read their feedback on InstaSPIN™-FOC:
develops techniques and manufactures equipment that contribute to a better planet. They are very successful with efficient misting systems for supermarkets to keep food fresh for twice as long and use 80 percent less energy. Contronics has also supplied ventilation fan controllers for a number of years and are pleased to release a new product that will change their industry: CoMoCo Intelligent Motor Control.

"The CoMoCo is the smartest electrical drive for fans in the world, and it is powered by TI's Piccolo microcontrollers and InstaSPIN-FOC technology. The built-in PowerWarp™ mode reduces current consumption to the bare minimum required at all times, enabling a 280W fan to consume less than 10W,while maintaining the same speed and commanded airflow. In our 14-month field trial, this resulted in overall energy savings of 80 percent versus triac controls and 50 percent versus InstaSPIN-FOC with PowerWarp disabled. Due to the high-precision speed and torque signals from the FAST™ encoder, we have turned the fan itself into a speed and flow sensor. This actually improves dynamic capability, eliminates costly hardware and simplifies installation." ―

"The TI Piccolo microcontroller-based InstaSPIN™-FOC solution gives us extremely robust, low-speed, high-torque performance that enables us to use quieter and smaller direct-drive motors without the cost or lowered reliability of a solution with a mechanical rotor sensor. The motor identification and auto tuning allows us to rapidly test new motors, and more importantly, to have a motor-drive system that just works. This allows our engineers to focus their efforts on innovation, such as additional rider enhancements possible with the unique, extremely high-resolution speed and torque signals from the FAST™ software encoder."

specializes in electric road mobility, providing electric motor and drive solutions for a variety of specialized vehicles, such as busses, refuse trucks and passenger cars with a goal to increase efficiency of electric drivetrains in order to reduce CO2 emissions, noise levels, pollution and the dependence on fossil fuels.

"A world of vehicular electrification is enabled through TI's Piccolo microcontroller with InstaSPIN™-FOC and the FAST™ software encoder, which provides a single, sensorless solution that works across any motor type, power range and variable speed and load conditions. We use the same software solution for high voltage but varying current asynchronous pumps, compressors and starter generators. And we have just removed the mechanical rotor sensors on our synchronous in-hub motors for passenger vehicles and busses, eliminating a major source of development challenges while increasing safety and reliability. Because the torque control from InstaSPIN-FOC works so well, we can focus our efforts on system communications and diagnostics, product enhancements and new inventions that make the world a cleaner and greener place to live."
