The Zhong Hua Jiang ER20 2.2KW air cooled spindle motor is built for buyers who need a practical balance of power, precision, cooling efficiency, and easy installation. It is a suitable spindle choice for CNC router upgrades, replacement spindle projects, small production workshops, CNC machine assembly, and spare-parts distribution.
Unlike water-cooled spindle systems, the air-cooled structure does not require a water pump, coolant tank, or circulation pipe. This reduces installation complexity and maintenance cost while keeping the spindle compact and easy to service.
For B2B buyers, Zhong Hua Jiang supports factory-direct supply, bulk purchase, OEM branding, voltage configuration, packaging customization, and distributor cooperation for global CNC machine and CNC accessory markets.

This 2.2KW ER20 spindle motor is suitable for CNC users who process wood, acrylic, MDF, PVC, PCB materials, plastics, plexiglass, and soft metals such as aluminum or brass. It is commonly used in CNC router machines, engraving machines, woodworking equipment, sign-making machines, small production lines, and maintenance or retrofit projects.
Zhong Hua Jiang ER20 2.2KW air cooled spindle motor is engineered for stable high-speed engraving, milling, and cutting. It combines ER20 tool holding, 2.2KW power, efficient air cooling, and VFD speed control for professional CNC routers and workshop applications.
The spindle motor is designed for easy VFD speed control and practical daily operation. With a compatible 400Hz VFD, users can adjust spindle speed according to material type, tool size, and machining requirements.
The ER20 collet connection provides secure tool holding and supports larger tools than compact ER11 spindle models. This improves versatility for engraving, cutting, and light milling applications.
The spindle can be integrated with common CNC router control systems and matched VFDs. This makes it suitable for machine upgrades, OEM machine assembly, and replacement spindle projects.
Voltage options include 110V, 220V, and 380V configurations. The 8.5A current specification and 400Hz frequency support stable high-speed spindle performance when paired with a suitable VFD.
The spindle supports a speed range of 10,000–24,000 RPM, helping users choose suitable cutting conditions for wood, acrylic, plastic, PCB, and soft metal materials.
The air-cooled structure helps dissipate heat efficiently without water-cooling accessories. With a Φ80mm × 300mm body and approximately 5KG weight, it provides a practical balance of compact installation and stable operation.

Advanced dynamic balancing technology helps reduce vibration during high-speed operation, lowers operating noise, and improves machining stability during engraving, cutting, and milling.

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