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.
