Mitsubishi Electric integrated a motor and controller into the world’s smallest and lightest motor controller unit for electric power steering in automobiles, according to the company. 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. Steering assistance capabilities have been upgraded by improving the output performance of the motor by 30% through optimization of the electromagnetic design and use of the company’s original Poki-poki motor, which incorporates technologies that increase coil density. This prototype motor controller unit also features a control algorithm developed to provide steering sensation and stability. Mitsubishi Electric is slated to provide the motor controller unit to automobile and steering manufacturers in the near future.
