It is suitable for CNC woodworking, acrylic engraving, MDF cutting, PVC machining, PCB engraving, plastic milling, and soft metal processing such as aluminum and brass under suitable cutting parameters.

For B2B procurement, Zhong Hua Jiang can support trial orders, bulk orders, OEM/ODM requirements, voltage configuration, distributor cooperation, export packaging, and after-sales technical support for VFD parameter setting and installation.

Technical Specifications of 2.2KW Square Air Cooled Spindle Motor

Applications & Use Cases

Wood Engraving and Cutting

Suitable for wood signs, cabinet components, relief carving, MDF cutting, plywood machining, furniture panels, and customized woodworking products.

Acrylic and Plastic Engraving

The ER20 2.2KW square air cooled spindle motor provides stable high-speed performance for acrylic lettering, plastic panels, display products, and CNC engraving applications that require clean edges and repeatable accuracy.

Soft Metal Processing

With suitable tooling, feed rate, and cooling conditions, this spindle can process soft metals such as aluminum and brass for light-duty engraving, milling, and prototype work.

Features of ER20 2.2KW Square Air Cooled Spindle Motor

The Zhong Hua Jiang ER20 2.2KW square air cooled spindle motor is engineered for stable CNC engraving, milling, and cutting. It combines a rigid square body, ER20 collet compatibility, 10,000–24,000 RPM speed range, 400Hz VFD operation, upgraded bearings, and efficient air cooling for low-maintenance workshop use.

User-Friendly Control

The spindle is compatible with common VFD speed-control systems, making it easier for CNC machine builders and workshop operators to adjust RPM according to tool diameter, material type, and machining requirements.

High-Precision ER20 Collet System

The ER20 collet system provides secure tool clamping for larger tools than ER11 models, helping improve machining stability, cutting efficiency, and repeatable accuracy.

CNC Router and VFD Compatibility

Designed for CNC routers and engraving machines, this 2.2KW air cooled spindle should be equipped with a 400Hz VFD for proper speed control and stable operation.

Reliable Electrical Components

The 110V/220V configuration and 10A current rating support common workshop and machine-builder requirements. Zhong Hua Jiang also supports voltage matching and technical guidance for B2B customers.

Accurate Speed Regulation

The 10,000–24,000 RPM speed range enables flexible machining for wood, acrylic, plastic, PCB, MDF, PVC, and soft metals under suitable operating conditions.

Optimized Air-Cooling Design

The air-cooled structure helps dissipate heat without water pumps, coolant pipes, or water circulation systems. This reduces installation complexity and maintenance cost for CNC router users.

Advantages of Square Air Cooled Spindle Motor

Advanced Dynamic Balance Design

Dynamic balancing technology helps reduce vibration and operating noise during high-speed machining, improving spindle stability and surface finish consistency.

Extended Working Life

The spindle uses four upgraded steel bearings and an all-copper rotor coil design to support stable electrical performance and longer working life under regular CNC workshop use.
