Original Press Release:

High Performance 3-Phase DC Motor Torque Controller!

Bohemia, New York – Data Device Corporation (DDC) introduces a new 3-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 3-phase brushless DC motors. The controller provides complementary four-quadrant operation making it ideal 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

- Self-Contained 3-Phase Motor Controller

- Programmability Allows Common Design to be Used Across Multiple Application Platforms

- Fewer Components = Better MTBF Rating and Higher Reliability

• Complementary Four-Quadrant Drive Offers Performance Advantages Over Standard Drives

- Holding Torque Through Zero Current

- Linear Current Control Through Zero

- No Deadband at Zero

• Zero Current Holding Torque Control Enables High Accuracy Positioning and Control for Critical Applications

- 7% Linearity

- 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.
