OM9369CM

P R E L I M I N A R Y FULL-FEATURED POWER MODULE FOR HIGH-VOLTAGE DIRECT DRIVE OF 3-PHASE BRUSHLESS DC MOTORS 25 Amp. Push-Pull 3-Phase Brushless DC Motor Controller/Driver Module in a Ceramic-to-Metal Sealed Module OM9369CM FEATURES Fully integrated 3-Phase Brushless DC Motor Control Subsystem includes power stage, non-isolated driver stage, and controller stage Rugged IGBT Power Output Stage with Soft Recovery Diode 25A Average Phase Current with 300V Maximum Bus Voltage Internal Precision Current Sense Resistor (6W max. dissipation) Speed and Direction Control of Motor Brake Input for Dynamic Braking of Motor Overvoltage/Coast Input for Shutdown of All Power Switches Soft Start for Safe Motor Starting Unique Lightweight Hermetic Ceramic-to-Metal Sealed Module (CERMOD (4.255" x 2.475" x .74") TM) APPLICATIONS Fans and Pumps Hoists Actuator Systems 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 OM9369CM to specific ...
