Description of SMC6M40-10-1
DESCRIPTION
The SMC6MXX-XX is an, integrated three-phase brushless DC motor controller/driver subsystemshoused in a 43 pin power flatpack. The SMC6MXX-XX is best used as a two quadrant speed controller forcontrolling/driving fans, pumps, and motors in applications which require small size. Many integral controlfeatures provide the user much flexibility in adapting the SMC6MXX-XX to specific system requirements.The small size of the complete subsystem is ideal for aerospace, military, high-end industrial, and medicalapplications.
