Integrated Motor Control Meets Aviation Needs

The trend in aircraft design is toward more efficient brushless DC motors. A integrated motor drive module for brushless DC motors from International Rectifier (El Segundo, CA) reduces the effort of programming the motor control and simplifies certification. Because the device is configured for sensorless field oriented control, the elimination of Hall sensors improves reliability while reducing component count. It enables the aircraft to achieve greater fuel economy and lower maintenance costs.
