Square CNC Spindle Air Cooled Motor 2.2KW 220V 400Hz ER20 Collet Ceramic Bearing

This square CNC spindle motor is a 2.2KW air cooled unit rated for 220V and 400Hz operation, fitted with an ER20 collet and ceramic bearings for high speed routing and milling on CNC machines.

Overview

This CNC spindle motor delivers 2.2KW of cutting power in a square body designed for CNC routers and milling setups. Air cooling keeps the spindle running without a water loop, and the ER20 collet accepts common router bit shanks. It suits hobbyists and small shops building or upgrading a CNC spindle setup that needs reliable high speed performance.

Specs At A Glance

Good To Know

Q: Does this spindle require a VFD? A: Yes, a compatible 220V 400Hz variable frequency drive is needed to run this spindle at proper speed.

Q: Are collets included? A: The listing title names the ER20 collet type, so confirm whether a collet or nut is included before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
