Compact 3-phase motor drive ensures fail-safe operations

Article By : Data Device

The new compact PW-82336 3-phase motor drive hybrid utilises a high-efficiency, radiation tolerant MOSFET output stage with 100 VDC rating to deliver 5A continuous current to the motor.

Data Device Corporation (DDC) has introduced a new high-reliability, 3-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 3-phase motor drive hybrid utilises a high-efficiency, radiation tolerant MOSFET output stage with 100 VDC rating to deliver 5A continuous current (10A peak current) to the motor. It has a flexible I/O allowing for common design to be used across multiple application platforms with individual bridge returns and standard logic level inputs to facilitate design implementation.

Other benefits include:

Eliminates 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 +15V) for the high and low-side gate drivers for each phase
Constant output performance for switching frequencies from DC to 50kHz provided by the internal charge pump circuitry
100VDC rating with 5A continuous, 10A peak current capability
100k Rad Total Dose (Si)
Small size: 66mm x 35.6mm x 6.35mm (2.6in x 1.4in x 0.25in)

“Packaged in a small case with internal logic for optimised performance, this high-reliability motor drive is an excellent choice for servo-amplifiers and speed controls in high performance space, aerospace and military applications,” said Vincent Giardini, DDC product line director, Motor Control Solutions.
