MANHASSET, NY -- Revenue derived from the use of magnetic sensors in automotive motors will expand by nearly 40 percent in 2012 reaching $160.3 million, according to market research firm IHS iSuppli.
While revenue growth after 2012 will moderate to single digits, the five-year compound annual growth rate from 2010 to 2015 will equate to a robust 16 percent. By 2015, magnetic sensor revenue in automotive motors will amount to $193.6 million. The automotive industry accounts for half of semiconductor magnetic sensor market revenue.
The average car make use of as many as 100 small motors, performing tasks ranging from enabling the power steering, to actuating the fans in the heating, ventilation and air conditioning (HVAC) system, according to Richard Dixon, senior analyst for MEMS & sensors at IHS.
An important driver for efficient motors is energy consumption, where fractions of a liter in fuel savings can be critical—and each gram of carbon dioxide produced as emissions is counted. Here, the trend is toward the electrification of pulley-driven motors and replacement by brushless DC motors. These efficient motors allow on-demand operation of the main powertrain components.
Use of anisotropic magnetoresistive (AMR) sensors will increase in the next five years. NXP Semiconductors is a major provider of AMR sensors, while Hall sensor IC alternatives are supplied by Micronas of Switzerland, Infineon Technologies, - Allegro Microsystems, Melexis N.V. and Asahi Kasei Microsystems.
I never knew that a single could have that many motors running inside concurrently. It just goes to show how complicated our cars are becoming compared to maybe a decade ago. As they become smarter, more and more technology goes into them, making them more efficient machines.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
