Motors & Rotors

High-temperature, precision arc magnets with strict flux consistency for electric motors.

Target Buyer:Motor OEM engineering teams.
Arc segment magnets for rotor solutions

Solution Highlights

  • High intrinsic coercivity (Hcj)
  • Precision air-gap control
  • Flux pairing and grouping

Common Use Cases

  • EV Motors
  • Industrial Servos
  • Drones

Implementation Focus

  • Demagnetization resistance
  • Weight reduction
  • Glue adhesion surfaces

Application Evaluation Matrix

Evaluation MetricTypical RangeBuyer Relevance
Flux Tolerance+/- 3%Ensures smooth motor rotation (low cogging)

RFQ Preparation Checklist

  1. Rotor operating temp
  2. Required flux tolerance
  3. Segment dimensions

Risk and Mitigation

  • High temp demagnetization: Select SH, UH, or EH grades

Cross-Functional Review Before PO

For motors & rotors projects, buyer teams usually avoid rework when engineering, quality, and sourcing align on one shared review memo before purchase release. Keep this memo attached to the RFQ thread and update it at each revision.

OwnerMust-Confirm InputRelease Decision
Design EngineeringGeometry baseline, tolerance stack, and interface limitsFreeze drawing revision and acceptance criteria ownership.
QualityCTQ dimensions, outgoing checks, and record formatConfirm measurable pass/fail gate before pilot expansion.
ProcurementLot sizing, lead-time assumption, and shipment termsLock commercial terms only after technical memo is complete.

Practical Handoff Notes for Buyer Teams

  1. Keep one version-controlled checklist that links drawing revision, sample result, and PO release note in the same thread.
  2. When requirements change, state whether impact is only dimensional or also affects coating, magnetization, packaging, and delivery.
  3. Ask suppliers to mark assumptions explicitly in quote replies so your internal approvers can detect hidden scope mismatch early.
  4. For global delivery programs, align inspection records and export documentation fields before moving from sample to MP.

Application Readiness Review Before Program Freeze

In application-driven programs, most cost and schedule deviations start from missing assumptions rather than supplier execution alone. Run a readiness review before PO freeze so your design, quality, and procurement teams validate the same risk model.
