Brushless power tools

Magnets and motor parts for power tools

EMTXI sources custom neodymium magnets and related components for brushless power-tool motors. We work from the tool maker's drawings and operating requirements, compare external production routes, and return a quotation with the proposed material, inspection scope and delivery plan.

Illustrative geometry. Not a product drawing.

Start from the tool's duty

A tool used intermittently and one operating through repeated loaded cycles can place different demands on the same-looking motor component. Provide the operating conditions used in your design assessment, including temperature, duty cycle and the tests required before a replacement part is accepted. We do not assign a material from the tool name alone.

For arc segments, rings or blocks, specify the magnetic properties, magnetisation direction, coating and finished dimensions. State whether the drawing describes the bare magnet or the coated part. The tolerance guide sets out the information needed to compare dimensional offers.

Separate component and assembly acceptance

Agree which features are checked on receipt and which are verified after assembly. A dimensional report on a magnet does not establish the performance of a completed rotor. If your programme requires assembly retention, balance, endurance or acoustic checks, identify who performs them, the acceptance method and the records to be supplied.

Stators, shafts, rotor carriers and housings can be included on request through motor component sourcing. Provide the applicable drawings and material requirements for each item. We keep component scope and assembly scope explicit so that suppliers quote the same work.

Control recurring deliveries

Describe how parts enter the assembly line: individual packs, identified sets or another agreed format. Mark any surfaces that must be protected during handling and state the labelling needed to connect deliveries with their inspection records. Packaging is agreed with the route; it should not be assumed from a previous supplier's practice.

For a volume programme, share forecast demand separately from firm releases. Include launch batches, expected changes between tool variants and the treatment of revised drawings. We assess additional routes and available capacity against the actual programme rather than publishing a fixed capacity promise.

Information for a comparable offer

  • Controlled component drawings and applicable specifications

  • Required magnetic properties and operating conditions

  • Coating, bonding surfaces and finished-size requirements

  • Sample plan and customer approval sequence

  • Delivery batches, packaging and lot-identification requirements

  • Target schedule and any origin restrictions

Where sourcing origin is a purchasing condition, define the relevant stages and acceptable documents using the origin-traceability guide. A proposed route remains subject to evidence review and customer acceptance.

Buyer questions

Can one magnet specification cover several tool models?

It may, where the tool maker has approved the shared part for each application. Identify the models and operating conditions; we quote against the common drawing and any variant-specific requirements.

Can you arrange assembled rotors as well as loose magnets?

Yes, as a sourcing request subject to a suitable route and agreed inspection scope. The quotation distinguishes loose components, assembly work, supplied materials and the records required for release.

Can an alternative material reduce sourcing constraints?

We can request alternative material proposals with the producer's data and supply-route details. Your engineering team must approve any change against the motor's operating conditions and qualification tests before series supply.
