The OMC507 is a three phase brushless DC Motor Controller Driver. The OMC507 is a 2 quadrant controller and provides control of motor current (torque) in proportion to the input current command. The versatility of the OMC507 allows the user to either provide an analog or a TTL PWM current command signal externally, or to set an analog current command onboard. The OMC507 also allows the user to adjust the current command offset onboard through the use of a potentiometer. Loop compensation is provided onboard and loop compensation component values can be modified to meet specific customer requirements, thereby optimizing the controller for each application. The OMC507 controller utilizes surface mount and through hole technology. The OMC507 is a mere 2 1/2 inches in diameter and can fit inside the motor housing. A connector for the control section is optional; consult the factory.
