1.5 kW 18000 RPM Square Air Cooled CNC Spindle Motor - 220V ER20
The 1.5 kW Square Air-Cooled Spindle Motor is a robust workhorse designed for high-speed industrial applications where precision and durability are paramount. Operating at 18,000 RPM with a 300 Hz frequency, this 220V motor is a primary choice for CNC router machines, PCB fabrication, and high-frequency bangle designing. Its square body design facilitates a more rigid and stable mount to the machine's Z-axis, effectively dampening vibrations during deep cuts or intricate engraving. Built with a high-grade P4 bearing arrangement (7005 & 7002), this spindle ensures superior rotational accuracy and extended service life, making it equally effective for automotive deburring and industrial brush manufacturing.
