EASYGEN-3500-5 Woodward speed control module

The EASYGEN-3500-5 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward EASYGEN-3500-5
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- EASYGEN-3500-5 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

4. Finally, it is necessary to consider leaving a certain (such as 50%) torque margin and speed margin.

5. You can first choose a hybrid stepper motor, and if there are price factors, you can choose a reactive stepper motor.

6. Try to select segmented drivers and make them work in a segmented state.

7. When selecting, do not fall into the misconception of only looking at the motor torque, which means that the larger the motor torque, the better.

It should be considered together with the speed indicator.

8. Ultra small and micro drives rely on the casing as a heat sink and should be fixed on larger and thicker metal plates or externally cooled by a fan.

If there is no heat dissipation condition and the drive operates at a lower speed (where the drive generates more heat), a 90 type drive with a fan can be used as a substitute.
