Sensorless Motor Drive for Harsh Environment
solution because typical Sensorless motor drives have been unsatisfactory. The most significant drawback to Sensorless designs has been the high current needed to start a Sensorless motor, while power efficiency and performance are also important. In response to these demands, Performance Controls has developed the DHT24-02. Key features include: Sensorless – elimination of a feedback device from the motor increases system reliability. Sinusoidal Commutation – A combination of advanced... (read more)
