الوصف
The GE DS2020LRPAG1 Resolver Module is a specialized printed circuit board (PCB) used in General Electric’s industrial control systems, primarily within the Mark V Turbine Control and the DC2000/Mark V drive series.
This module plays a crucial role in motion control feedback by interpreting signals from a resolver.
⚙️ Key Specifications and Function
| Feature | Specification/Description |
| Product Type | Resolver Feedback Module (LRPA) |
| Series/Family | GE Mark V Turbine Control and DC2000/Mark V Drives |
| Primary Function | Position and Speed Feedback. It conditions and processes the analog sine and cosine signals received from a resolver (an electromechanical transducer) mounted on a motor or turbine shaft. |
| Output | Converts the resolver’s analog signals into a digital format (e.g., quadrature signals or a digital word) that the main control system can use to precisely determine the rotor position, speed, and direction. |
| Input Signal | Accepts low-voltage, phase-shifted signals from the resolver. |
| Hardware | The board includes circuitry for signal conditioning, amplification, and analog-to-digital conversion (ADC) specific to resolver feedback. |
| Application | Critical for systems requiring high-precision speed and position control, such as large DC motor drives, CNC machines, and gas or steam turbine management. |
Part Number Breakdown
The specific code helps identify the board’s role:
- DS2020: Indicates the product generation/family (associated with the modular Mark V architecture).
- LRPA: Stands for Locator Resolver Panel Assembly.
- G1: Specifies the revision or configuration of the board.
In a closed-loop control system, the DS2020LRPAG1 is indispensable as it provides the necessary feedback loop that allows the control system to accurately regulate the motor’s output based on its actual rotational state.
