Description of SMC6M40-25-1
DESCRIPTION
The SMC6M40-XX is an, integrated three-phase brushless DC motor controller/driver subsystems housed in a 43 pin power flatpack. The SMC6M40-XX is best used as a two quadrant 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 SMC6M40-XX to specific system requirements. The small size of the complete subsystem is ideal for aerospace, military, high-end industrial, and medical applications.
