Spare Parts: 71718 Copper Carbon Brush for Replacement
1. Product Identification
Type: Replacement copper carbon brush (a consumable spare part for electrical equipment).
Model Number: 71718 (unique identifier for compatibility with specific devices).
Material: Copper-graphite composite (contains copper to enhance conductivity, typically 20–30% copper content).
2. Core Function
Electrical Conduction: Transmits current between stationary and rotating components of motors (e.g., from power source to rotor via contact with commutator/slip rings).
Wear Resistance: Designed to wear gradually during operation, protecting critical motor parts (e.g., commutator) from damage.
3. Key Features
Copper Blend Advantage: Higher conductivity than pure graphite brushes, suitable for motors with higher current demands.
Durability: Copper addition improves mechanical strength, ideal for high-vibration or heavy-load equipment.
Standardized Design: Model 71718 follows specific dimensions (implied by the part number) for precise fit in compatible devices.
4. Typical Applications
Compatible with motors in industrial machinery, power tools, generators, or household appliances (verify with device manual using model 71718).
Suitable for brushed motors requiring reliable current transfer under moderate to high load.
5. Replacement Scenarios
When original brush is worn to <50% of original length.
Excessive sparking from motor during operation (signals poor contact).
Reduced equipment performance or intermittent operation due to brush degradation.
6. Installation Note
Ensure compatibility with device model using part number 71718 to avoid size mismatch.
Replace in pairs (if applicable) to ensure balanced wear on commutator.
Clean commutator surface before installation to remove carbon dust buildup.
