I. Function and Structure of Carbon Brushes- Carbon brushes conduct current, enabling the rotor to function as an electromagnet.- The brush contact points are made of graphite, which provides self-lubrication.II. Analysis of Carbon Brush Wear Causes1. Usage-Related Causes - Dust in the operating e Read More

Motor Repair RecommendationsI. Core Recommendation- When a motor fails, it is recommended to replace the entire motor rather than replacing only the rotor or stator separately.II. Reason Analysis1. Motor Construction Differences: - Motors from different manufacturers vary in the number of coil tur Read More

I. Problem Overview- The diesel generator starts but then stalls.II. Key Component- Solenoid Valve: Located on the oil pump, it is the actuating mechanism for the engine oil protection device.III. Function of the Solenoid Valve- After starting, it automatically cuts off the fuel pump's function to p Read More

Pre-Operation & Inspection:1. Read Manual: Thoroughly read and understand the operator's manual.2. Visual Inspection: Check for any shipping damage, loose parts, or fluid leaks.3. Fluid Levels: Add and Confirm all fluids are at the correct level (engine oil, coolant if liquid-cooled, fuel).4. Batter Read More

For Undervoltage:1. Low Engine Speed (RPM): The most common cause. Engine not running at rated speed.2. Faulty AVR (Automatic Voltage Regulator): AVR is failing to supply sufficient excitation current.3. Overloading: Connected load exceeds the generator's capacity.4. Poor Connections: Loose or corro Read More

1. Faulty AVR (Automatic Voltage Regulator): The AVR fails to supply or control the DC current needed to create the rotor's magnetic field.2. Brush/Wearing Issues (if applicable): Worn-out, stuck, or dirty brushes prevent excitation current from reaching the rotor.3. Failed Rotating Diodes (if appli Read More
