Walter Motor Factory
Inside Walter Motor’s manufacturing system for roller shutters, roller blinds, awnings, zip screens and smart shading systems.
Why Factory Capability Matters for OEM Motor Buyers
For OEM brands, distributors and project buyers, choosing a tubular motor supplier is not only about price. The real question is whether the factory can keep torque, speed, noise, braking, limit accuracy and delivery stable across repeat orders.
Walter Motor is a tubular motor manufacturer based in Jiaxing, Zhejiang, China. Our manufacturing system is built around core component control, standardized assembly, documented inspection and long-term OEM cooperation. This helps customers reduce supplier risk, improve product consistency and support private-label or project-based motor programs.
Factory Overview
Walter Motor manufactures tubular motors and related drive solutions for roller shutters, roller blinds, awnings, zip screens, projection screens, smart shading systems and OEM or ODM motor projects.
Our factory capability covers the main manufacturing and inspection stages required for stable tubular motor production, including metal tube processing, stator and rotor lamination control, rotor die-casting and CNC machining, winding, plastic component manufacturing, gearbox assembly, final motor assembly and product testing.
This page shows how Walter Motor controls each key process from raw material preparation to finished motor inspection.

Core Manufacturing Capabilities
The sections below show the production controls that matter most when a buyer needs repeatable tubular motor production rather than a one-time sample.
1Motor Tube Processing and Surface Treatment
The motor tube is both the outer structure and the protective housing of a tubular motor. Diameter accuracy, roundness, edge finishing and surface protection all affect assembly stability and long-term performance.
- Tube forming and diameter consistency
- Cutting and length control
- Edge finishing
- Surface pretreatment
- Powder coating or surface protection where required
For outdoor applications such as roller shutters, awnings and zip screens, stable tube quality helps improve corrosion resistance, mechanical strength and installation reliability.
2High-Speed Stamping for Stator and Rotor Laminations
Stable motor performance starts from the electromagnetic core. Walter Motor uses high-speed stamping equipment for stator and rotor laminations, including Yangdu presses and a Japan-made AIDA press.
The stamping line can operate up to 350 strokes per minute, supporting large-volume production while maintaining dimensional consistency.
- Lamination shape accuracy
- Slot consistency
- Core stacking quality
- Batch-to-batch stability
- Motor efficiency and noise consistency
After stamping, stator and rotor laminations are processed through automatic stacking and interlocking. The laminated cores are then compacted and verified to support stable motor performance in mass production.
3Thermal Blueing Treatment for Stator Laminations
Stator laminations may undergo thermal blueing treatment to improve the stability of the magnetic core after high-speed stamping.
- Release internal stress generated during stamping
- Improve magnetic consistency
- Support lower noise and better thermal behavior
- Improve long-term motor stability
4Rotor Die-Casting and Precision CNC Machining
The rotor is one of the most important rotating components in a tubular motor. Walter Motor controls rotor manufacturing through aluminum die-casting, shaft press-fitting and CNC machining.
- Rotor density and casting quality
- Shaft alignment
- Concentricity
- Rotor diameter finishing
- Brake-side machining
- End-face accuracy
- Dimensional tolerance verification
A stable rotor reduces vibration, improves running smoothness and supports consistent braking and torque transmission.
5Stator Winding and Electrical Assembly
The winding process directly affects current, temperature rise, torque output and motor consistency. Walter Motor uses controlled winding and stator assembly processes to keep winding turn count, tension and coil distribution stable.
- Controlled winding tension
- Accurate turn count
- Uniform coil distribution
- Coil insertion and forming
- Insulation protection
- Hi-Pot and inter-turn testing after winding
Each stator assembly must pass electrical inspection before it moves into later assembly stages.
6Plastic Components and Structural Parts
Tubular motors rely on many internal and external plastic parts, including motor heads, end caps, gearbox-related parts, brackets and internal support components.
- Assembly fit
- Gearbox stability
- Dimensional consistency
- Long-term durability
- Noise and vibration control
Walter Motor controls plastic component production and inspection to support repeatable assembly quality across production batches.
7Gearbox Assembly, Brake System and Limit Mechanism
For roller shutters, awnings and larger blinds, the gearbox and brake system are critical to safety and service life. Poor gear matching, incorrect lubrication or unstable brake force can cause noise, slipping, load failure or inconsistent limit operation.
- Gear meshing accuracy
- Lubrication consistency
- Bearing and shaft fit
- Brake holding force
- Mechanical limit switch assembly
- Electronic or receiver-related control assembly where applicable
This process helps ensure stable torque transmission, reliable stopping and repeatable upper/lower limit performance.
8Final Assembly Line
During final assembly, the motor tube, stator, rotor, brake, gearbox, limit system, wiring and motor head are integrated into the finished tubular motor.
Walter Motor uses standardized assembly procedures and in-process checks to reduce human error and maintain repeatable quality.
- Component matching
- Wiring connection
- Torque-controlled fastening where applicable
- Limit mechanism setting
- Visual inspection
- Process checkpoints before final testing
Testing and Quality Validation
A reliable tubular motor factory must prove quality through testing, not only through product appearance. Walter Motor’s inspection system includes electrical safety testing, functional testing, performance verification and batch traceability.
Electrical Safety Testing
- Insulation resistance
- Ground continuity or earthing resistance where applicable
- Dielectric withstand or Hi-Pot test
Functional and Performance Testing
- No-load and load current or power
- Rotation speed and torque or load performance
- Brake holding force and travel limit repeatability
Aging and Batch Reliability Control
Walter Motor performs 100% electrical and functional inspection on finished motors. Aging or endurance tests are performed by production batch, product type or customer requirement to verify thermal stability and long-term reliability.
Traceability
Each production batch is controlled through inspection records and production documentation. This helps customers trace quality issues, review production history and support long-term OEM cooperation.
