3.8 kW / 5 HP CNC Spindle Motor – ISO 30 Tool Holder, Air Cooled (ES915 Series)

The HSD ES915 ISO 30 spindle is a compact, high-efficiency motor built for industrial CNC routers and milling machines requiring air-cooled operation and stable output. With a continuous rating of 3.8 kW (S1) and peak output up to 4.6 kW (S6), this 2-pole asynchronous motor delivers smooth power across a wide speed range up to 24 000 RPM.
Its ISO 30 tool interface supports rapid tool changes and secure clamping for routing, drilling, and engraving operations. An integrated fan cooling system ensures steady temperatures without external chillers, reducing maintenance needs and improving uptime.
Compact aluminum housing and precision ceramic bearings provide low vibration and excellent longevity under continuous duty. Ideal for wood, composite, and aluminum processing where accuracy and speed matter.
