Electric motors - from the large to the extremely small and with speeds ranging from fast to slow - power all sorts of products and equipment in the modern world. They implement everything from convenience features such as power seat adjusters in automobiles to huge precision machine tools in factories. Truly, advances in motor technology enable the progress of society in general, and those advances are ongoing. Electric motors are being improved and better ways of controlling them are being introduced, such as sensorless control methods and techniques for achieving more precise motor operation.
In the area of microcomputers, system engineers are seeking simpler chips for some motor control applications, and different devices with higher performance and greater sophistication for others. Design teams are constantly looking for more ways to save energy, too. Thus, modern solutions for controlling electric motors must do more than just operate the motor; they must be energy efficient and work well in the surrounding environment.
Renesas motor control solutions are driving - literally! - the next generation of advances in electric motor applications. Our customers are developing and producing a vast range of motor-driven products, facilitated by the extensive range of microcomputers we offer. Our latest devices are characterized by improved computing capabilities, enhanced or simplified on-chip functionality, and engineering support that eases the design of highly reliable, cost-effective control electronics.
In this five-part Special Feature, we offer insights into trends and developments in motor control technology, then discuss the basic Renesas strategy for serving the diverse needs of this vast global market. Next we describe three key types of applications, highlighting the best microcomputer choices for each and presenting case studies that reveal how customers apply our motor control solutions. A subsequent article covers development systems and our technology partners. We conclude by describing the Renesas power devices that are used to drive various types of electric motors.
