DDC Introduces Torque Controller

July 23, 2013
Data Device Corporation (DDC) introduces a new three-phase DC motor torque controller. The PW-82530N0 is a high performance and low cost torque loop controller designed to precisely regulate the current in the motor windings of three-phase brushless DC motors. The controller provides complementary four-quadrant operation making it suitable for applications requiring precise current regulation and/or holding torque at zero input command.

Benefits include:
•    Single-module solution more efficient than in-House and multi-component designs
o    Self-contained three-phase motor controller
o    programmability allows common design to be used across multiple application platforms
o    Fewer components = better MTBF rating and higher reliability
•    Complementary four-quadrant drive offers performance advantages over standard drives
o    Holding torque through zero current
o    Linear current control through zero
o    No deadband at zero
•    Zero current holding torque control enables high accuracy positioning and control for critical applications
o    7% linearity
o    3% current regulating accuracy
•    10 amp output current
•    -40°C to +100°C operation

“Complementary four-quadrant drive capability enables the PW-82530N0 to offer highly linear current control and superior holding torque, especially during a zero current command, affording it significant advantages over standard motor controllers, in a low cost package”, stated Steve Rood Goldman, DDC’s marketing manager.
