SMCT6G060-120-1

DESCRIPTION

SMCT6GXXX-XXX is a completely self-contained 4-quadrant motor controller that converts an analog input command signal into a motor current. The motor current is internally sensed, processed, and used as an output for the closed current loop feedback control. Error amplified input and output are available for closed loop compensation. Proportional or proportion/integral (PI)  compensation can be implemented to optimize motor and system performance. SMCT6GXXX-XXX is  best used as a four-quadrant torque controller for controlling servo systems.   The SMCT6GXXX-XXX is a fully integrated three-phase brushless DC motor control module housed in a 43 Pin power flatpack. Many integral control features provide user flexibility in adapting the SMCT6GXXX-XXX to specific system requirements. Current control or closed loop speed control can be easily implemented.  The small size of this complete motor control module makes it ideal for commercial aerospace and military applications.
