Magnetic components

Laminated Magnets

Segmented magnets with inter-segment insulation and an overall epoxy coating, configured for motor designs that need to limit eddy-current paths.

Arc · block · sector: Available shape familiesSegmentation follows the drawing.
Insulated: Between magnet segmentsRequirements agreed for the motor design.
Epoxy coating: Overall coating optionSpecification follows the application.

Segmented magnet structures

Shape and lamination direction are defined together.

Laminated blocks

Block forms use segmented construction with insulation between the magnet pieces.

Coated magnet stacks

Finished shape, stack orientation and coating are reviewed as part of the component design.

Product examples

Layered and coated magnet forms from different views.

Overlapping pieces with visible segmentation and curved ends.

Rectangular blocks in upright and flat orientations.

Dark coated pieces arranged as short stacks.

Single coated piece with a broad face and rounded corners.

Block forms showing the segmented face and edge construction.

Required engineering inputs

Lamination details are specified for the motor, rather than selected from a universal thickness range.

Finished shape	Provide the arc, block or sector drawing and the finished assembly envelope.
Lamination	Specify segment thickness, segmentation direction and stack dimensions.
Insulation and bonding	Define insulation, bonding and acceptance requirements between segments.
Coating	State the required overall epoxy specification and environmental conditions.
Motor conditions	Provide operating temperature, speed and magnetic-circuit requirements for design review.

Final stack dimensions, insulation, coating and acceptance conditions follow the agreed drawing. Eddy-current and thermal behaviour depend on the complete motor design.

Define the stack

We review the segmented shape, insulation and coating requirements, including interfaces for integration into Halbach assemblies.

Insulation and assembly

Segment the magnet: Arc, block and sector forms can be divided into the segments defined in the drawing.
Insulate and bond: Inter-segment insulation interrupts eddy-current paths. Bonding and overall epoxy coating follow the component requirements.
Agree acceptance: Specify the finished dimensions, insulation requirements and inspection scope before the stack is approved for manufacture.

Prototype to production

Prototype: From 1 set
Sample schedule: Typically 5–8 working days for mature drawings; 7–15 working days for new design and tooling
Production MOQ: Confirmed by specification; production typically 15–30 working days, depending on quantity
Packaging: Magnetic shielding and protective packaging

Sample and production schedules depend on segmentation, insulation, tooling and quantity. Timing starts after drawing confirmation and receipt of sample payment.

For high-speed axial-flux and permanent-magnet motor designs; evaluate the stack against the complete magnetic and thermal design.
