1. Product Identification
Part Number: 10090596
Product Type: Carbon brush holder (a component that houses and secures carbon brushes)
Application: Specifically designed for the PH65A electric pick (a handheld power tool used for breaking, chiseling, or demolition work).
2. Core Function
Serves as a protective and positioning structure for carbon brushes in the PH65A electric pick’s motor.
Secures carbon brushes in place, ensuring stable contact with the motor’s commutator to transmit electrical current.
Integrates springs (often built into the holder) to maintain consistent pressure between brushes and commutator, even under high vibration from the pick’s operation.
3. Key Role in Electric Pick Operation
Enables reliable current conduction from the tool’s power source to the motor’s rotor, driving the pick’s chiseling/breaking motion.
Protects brushes from damage due to the tool’s intense vibration and 冲击 (impact) forces during use.
Ensures proper alignment of brushes with the commutator, preventing uneven wear and excessive sparking.
4. Replacement Scenarios
When the holder’s structure is cracked, deformed, or broken (compromising brush stability).
If the built-in spring loses tension (causing poor brush-commutator contact, leading to weak performance or sparking).
As a (matching) part when replacing worn carbon brushes in the PH65A electric pick, ensuring optimal fit and function.
5. Compatibility Note
The part number (10090596) and specific design are tailored to the PH65A electric pick model. Using an incorrect holder may result in improper brush alignment, motor damage, or tool malfunction.
6. Installation Consideration
When replacing, ensure the holder is securely fastened to the motor housing to withstand the electric pick’s high-impact operation.
Verify that the holder’s spring tension is adequate to keep brushes in consistent contact with the commutator.
