Review the questions below alongside the page information. Keep the original part reference, agreed specification and any project-specific requirements with your inquiry.
Check whether its motor is brushed or brushless. Brushless motors do not use carbon brushes for commutation. Use the exact model and parts diagram, because tools sold under the same product family may use different motor designs.
No. The motor reference and original brush specification are needed as well. Provide the carbon dimensions, connection and holder details. A battery-platform label does not identify the brush grade or make parts interchangeable across tools.
Follow the tool maker's service arrangement. If the motor is not specified for loose-brush replacement, do not assume it can be serviced that way. Send the motor assembly reference and parts diagram so the requested supply can be checked against the intended repair.
Include a dimensioned drawing of the carbon body and holder interface, the lead exit and terminal, and the original part reference. Photos should show the connection and assembly orientation, not just the worn carbon tip.
A runtime improvement needs testing on the particular motor and tool under defined conditions. Do not select a substitute on an advertised efficiency percentage or material name alone. Start with the original specification and define any proposed validation with the motor designer.
Separate each model and motor version, even when the tools share a battery. List the original references and quantities and flag any missing drawings. Confirm a cross-reference before stocking one replacement for several tools.
