Data Device Corporation (DDC) Offers Three-Phase Motor Drive

Data Device Corporation (DDC) introduces a new high-reliability, three-phase radiation tolerant motor drive, providing 100k Rad Total Dose protection, and advanced circuit and logic protection to ensure fail-safe operation. The new compact PW-82336 three-phase motor drive hybrid utilizes a high-efficiency, radiation tolerant MOSFET output stage with 100 VDC rating to deliver 5A continuous current (10A peak current) to the motor, along with flexible I/O, enabling a common design to be used across multiple applications. Benefits include a flexible I/O that allows common design to be used across multiple application platforms with individual bridge returns and standard logic level inputs to facilitate design implementation, the elimination of shoot-through conditions with high and low-side input logic signals XOR's in each phase to prevent simultaneous turn on of in-line transistors, internal logic controls (from +5 to +15 V ) for the high and low-side gate drivers for each phase and more. “Packaged in a small case with internal logic for optimized performance, this high-reliability motor drive is an excellent choice for servo-amplifiers and speed controls in high performance space, aerospace and military applications” stated Vincent Giardini, DDC product line director, Motor Control Solutions.
