Field-oriented control DC motor speed controller
Sensitron Semiconductor

The Digital Vector Motor Drive is a digital motor controller designed for high reliability and industrial motor control applications. This controller utilizes space vector modulation control design for maximum utilization of the DC bus voltage and provides smooth torque control. The DC bus voltage operating range is 100V to 800V. The flexibility of this design allows use of a single device/part number for multiple motor applications with few hardware changes. There are two internal assemblies in a small footprint module: the Field Oriented Control (FOC) hardware and a 3-Phase Bridge. The FOC hardware is programmable via an isolated RS-232 input port, and the 3 Phase Bridge designs are rated up to 40A,1000V utililizing IGBT's or 60A, 150V with MOSFETs. The sensorless algorithm allows start up to be tuned for almost any load.

This product is intended to be used in high reliability military and industrial motor control applications. The design can be used for pump and fan applications in the following markets:
-Military Ground Vehicles
-Industrial Equipment
-Heavy Duty Vehicles
-Lifts
-Compressors
-Fans
