Sine-Wave PWM Drive Controllers that Allow Low Noise/High Efficiency Drive for Three-Phase Brushless DC Motors
Toshiba has launched the sine-wave PWM drive controllers “TC78B043FNG” and “TC78B043FTG,” designed for three-phase brushless DC motors, for low-noise, high-efficiency control of both SPM and IPM motors. The new products achieve low noise motor operation through high-resolution sine-wave drive and sine-wave startup control, while delivering high-efficiency motor control through parameter adjustments, such as lead angle control.
