Description

The OM9369CM is one of a series of versatile, integrated three-phase brushless DC motor controller/driver subsystems housed in a CERMOD TM. The OM9369CM is best used as a two quadrant speed controller for controlling/driving fans, pumps, and motors in applications which require small size. Typical size brushless DC motors that the OM9369CM can effectively control range from fractional HP up to several HP. The OM9369CM is ideal for use on DC distribution busses up to and including 270Vdc. Many integral control features provide the user much flexibility in adapting the OM-9369CM to specific system requirements.

The small size of the complete subsystem is ideal for aerospace, military, and high-end industrial applications.
