Stamped by the progressive mold

CMM tests tolerance

Interlock inside the mould directly

Test length one by one by go-stop gauge

Stack again by the fixture tooling


Motor laminations Introduction:
Servo motor is the fastest growth in recent years, the future of the highest prospects, one of the hot market focus of the industry.
This type of stator and rotor stamped by the progressive mold and with the interlock stack technology,which realized in the mold directly.Normally we use BAO STEEL,WU STEEL etc the famous brands electrical silicon material to make sure the stacks with perfect tolerance and performance.
We have different tonnage punch machines to meet different diameters requesment,such as 80T,160T,300T,400T,550T,630T.
Some for the high length stator lamintations ,beside interlock,we adopt the buckles or welding on the out diameter to strength it again.
95% of these products customized.At the beginning of the testing period,we can provide the Motor laminations samples by laser cutting or wire cutting.


Inspection of raw material01

Compound/Progressive mold

Assembly and debugging die

Feeding and stamping, then send the first piece of stator and rotor for inspection

Measure the size of the stator and rotor laminations with Micro Vu projector

After passing the inspection, stamping it normally, and patrol it once every two hours. Each time, a piece of stator or rotor is extracted for testing

Make stator and rotor stacks with laminations

Marking stator and rotor stacks( marking code complete, clear, no missing marking)

The slot is clean and tidy, and the buckle does not exceed the bottom of slot

The product surface is smooth, no warping tooth, warping piece, bruising, unpolished solder joint, no sundry

The products are free from rust, cracks, weld beading, garbage, wrong pieces, broken pieces and glue residue

The mark slot is error-free pieces

Keyway alignment, no error and deformation

Welding is free from desoldering, broken welding, missing welding, weld beading, steps, rust and protuberance of the outer circle

The reverse side of the product is no marking

Measure the size of the stator or rotor stack with Wenzel CMM

After passing the inspection, pack up for shipment


Stator and Rotor Technology

Due to the different requirements of stamping and motor performance, our stator laminations is divided into: interlock, welding, buckle strip, self-adhesive, glued; rotor lamination is divided into: interlock, rivet, self-adhesive, glued, bolt, cast aluminum.

For example: the high-speed stamping motor laminations of the progressive mold will adopt the interlock method, with rectangular and circular lock points respectively. If the Length of the stator laminations exceeds the interlock pull-out force range, we will add an additional amount to the outer diameter with Buckle and welding process reinforcement.

About Backlack material adhesive technology:
The "quick curing" process jointly developed with Baosteel replaces the original welding and riveting process, which can reduce the NVH and iron loss of the driving motor of new energy vehicles and improve the efficiency;The curing time of a single iron core is 4-8min, which is characterized by fast, low cost and short development cycle.


Application of motor laminations for servo motor:
The output power of AC servo motor is 0.1-100W, and the power frequency is 50Hz, 400Hz, etc. It is widely used, such as automatic control, automatic recording and other systems, punch press, printing equipment, laser processing equipment, automatic production line and other equipments with higher requirements for process progress, processing efficiency and work reliability.
DC servo motors can be used in respark machines, manipulators, confidential machines, etc.
In these applications,our motor laminations plays an important role.
