Magnets and components for robotics and actuators
EMTXI sources custom neodymium magnets and related motor components for industrial robot joints, servo motors, grippers and electric actuators. We compare external production routes against your drawing, agree the sample and inspection requirements, and coordinate the transition to recurring supply from Belgium.
Define the part in its assembly
A robot joint, servo axis and linear actuator need different component arrangements. Start with the magnet or rotor drawing and identify the assembly interfaces that must stay fixed. For arc segments, rings or blocks, specify the magnetisation direction and the condition in which parts should arrive. Include the drawing revision used by your assembly team.
Surface finish, coating allowance and inspection datums belong in that specification. If a shaft, rotor carrier or housing is also required, provide its mating dimensions and a separate acceptance drawing. We can quote these together as a motor component kit, with responsibilities identified for each part.
Qualify against motion requirements
State the temperature range, duty cycle and environmental exposure from your motor design. Any proposed magnetic material is reviewed against those requirements; a grade name by itself does not establish performance in a particular actuator. The grade guide explains the distinction between material properties and operating conditions.
Where positioning behaviour, vibration or acoustic performance matters, define the checks that your team will carry out on the assembled motor. Component measurements support that work but do not replace it. Agree whether samples are needed for fit checks, magnetic measurement, assembly trials or a complete customer test sequence.
Keep qualification attached to the route
The comparison should identify the proposed producer, material specification, coating, inspection method and any departures from the drawing. Sample approval applies to the agreed route and revision. A later change of material, coating or production location needs review against the agreed change procedure.
For origin-sensitive programmes, specify the required evidence for each relevant supply-chain stage. Origin traceability is assessed separately from dimensional and magnetic acceptance. An assembly location alone does not describe the upstream magnet chain.

Forecast demand, order batches and delivery schedule
Origin requirements and the evidence needed for acceptance
If several actuator variants share parts, identify the common items and the differences. We use that information to assess a volume programme, including sample gates, purchasing forecasts and possible additional routes. Capacity and delivery commitments are confirmed in the quotation and agreed order terms.
Buyer questions
Can you quote an alternative to an existing servo-motor magnet?
Yes, using your drawing, material specification and agreed inspection criteria. An alternative route requires sample approval in your assembly; a matching grade label alone is not evidence of interchangeability.
Can you supply magnets as matched sets?
We can request sorting and packing to an agreed set specification. Define the property to be matched, the measurement method and the acceptable variation before quotation.
Can stators and machined actuator parts be included?
Sourcing can include stators, shafts, housings and rotor assemblies on request. Each item has its own drawing, supplier assessment and acceptance requirements; the quotation states the agreed scope.
