Description of SMCS6G070-060-1
DESCRIPTION
The SMCS6GXXX-XXX-1 is an, integrated three-phase brushless DC motor controller/driver subsystems housed in a compact power package. The SMCS6GXXX-XXX-1 is used in two quadrant modes of operation. Two-quadrant mode is recommended for steady operation because of the reduced switching losses. The controller is best used as a speed controller for controlling/driving fans, pumps, and motors in applications which require small size. Many integral control features provide the user much flexibility in adapting the SMCS6GXXX-XXX-1 to specific system requirements. The small size of this subsystem is ideal for aerospace, military, industrial, and medical applications.
