Back in November of 2010, Mitsubishi Electric Corporation (MEC) announced that it was actively developing what it claimed to be the "world's smallest and lightest" motor controller unit for electric power steering systems in automobiles. This compact unit is, according to Mitsubishi, half the size and 30 percent lighter than the company's current products, while offering equal power output.
Mark Rakoski, director of sales and engineering at Mitsubishi Electric Automotive America, outlined the significance of developing a lightweight controller unit, stating:

Development of the motor controller has progressed to the point where MEC is now ready to launch the unit. The company is currently working on deals with a number of undisclosed automobile and power steering manufacturers.Forty percent of new automobiles manufactured worldwide now incorporate electric power steering, which can improve fuel economy by three to five percent compared to those using hydraulic steering. To do this, automobile and steering manufacturers are increasingly calling for motors and controllers that are much smaller and lighter than current components. This not only improves fuel efficiency, but facilitates installation of power steering systems.

Mitsubishi Electric Develops World's Smallest, Lightest Motor Controller Unit for Automotive Power Steering
Integrated motor and controller enhances fuel efficiency
Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed the world's smallest and lightest motor controller unit for electric power steering in automobiles. This next generation motor controller unit is half in volume and 70% in weight compared to the company's current products with equal output, contributing to the enhanced fuel efficiency of automobiles.
Mitsubishi Electric has also upgraded steering assistance capabilities by improving the output performance of the motor by 30% through optimization of the electromagnetic design and the employment of the company's original Poki-poki motor, which incorporates technologies that increase coil density. This prototype motor controller unit also features a unique control algorithm developed to provide superb steering sensation and stability. Mitsubishi Electric will provide the product to automobile and steering manufacturers in the near future.
40% of new automobiles manufactured worldwide now incorporate electric power steering, which can reduce fuel cost by 3~5% compared to those using hydraulic steering. Automobile and steering manufacturers are increasingly calling for motors and controllers that are much smaller and lighter than current components to further improve fuel efficiency and facilitate installation of power steering systems. To fulfill these needs, Mitsubishi Electric has integrated the motor and controller into one unit, and aligned them on the same axis by improving the internal structure of the controller.
