DESCRIPTION:
SMCT6MXX-XX 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. SMCT6MXX-XX is best used as a four-quadrant torque controller for controlling servo systems.
The SMCT6MXX-XX 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 SMCT6MXX-XX 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.

COMMUTATION TRUTH TABLE
This table shows the Phase Output state versus the state of the Hall-Effect and Command Polarity Inputs. The commutation
o
coding shown reflects Hall-Effect sensors that are spaced at 120 mechanical increments. Also, internal protection logic disables
all three Phase Outputs when the Hall-Effect Inputs are set to an illegal condition (i.e., all logic low or all logic high).
