Motor Drive
GaN Reduces Size and Weight, Reduces Audible Noise, Enables Cooler Operation

There are several applications for brushless DC (BLDC) motors in vehicles including those used for motion control and positioning. The rise in vehicle electrification means that previously mechanically-driven applications such as power steering, transmission actuation, and engine cooling systems are being electrically-powered.

BLDC motors are simpler to maintain, more durable, more efficient, smaller, lighter, simpler to control, and less prone to failure than traditional brushed motors. This makes the BLDC motor more attractive in vehicles where space is limited, and frequent operation is required.

GaN FETs and ICs can further reduce the size and weight of BLDC motors, reduce audible noise, improve torque for faster reaction times, and increase efficiency for extended battery life.
