Improve motor reliability and performance with this precision commutator designed for smooth operation in a range of DC motor applications. Key benefits Increases motor efficiency and reduces vibration: precise contact surface and balanced construction help the motor run smoother and more consistently. Durable under high-speed rotation: made from wear-resistant copper to withstand repeated high-RPM use without losing functionality. Reliable fit reduces downtime: exact dimensions and 12-tooth design ensure stable engagement and fewer alignment issues during replacement. What it does and why you need it Restores electrical contact continuity in brushed DC motors to recover power delivery and consistent torque output. Minimizes sparking and uneven wear at the brush interface, extending the life of brushes and the motor. Offers a cost-effective replacement part to avoid premature motor failure and maintain device performance. Compatibility and applications Suitable for power tools, household appliances, and high-speed DC motors. Typical use cases: 1. Replacing a worn commutator in a handheld power tool to restore smooth drilling or cutting performance. 2. Repairing a small appliance motor (vacuum cleaner, blender, or fan) to stop intermittent power loss and reduce brush wear. 3. Upgrading or servicing high-speed DC motors in hobby or industrial equipment where stable rotation at high RPM is required. Specifications Material: wear-resistant copper Design: 12 teeth (segments) Dimensions: 23 x 8 x 17 (18) mm (OD ID H) Why this part stands out Copper construction for reliable conductivity and durability under load. Precise manufacturing for a consistent fit and fewer installation adjustments. Versatile compatibility across multiple device types without sacrificing performance. Purchase this commutator when you need a durable, precisely sized replacement to restore or improve the operation of tools, appliances, and high-speed DC motors.
