TS-21 Air Cooled Spindle ER11 (220V)
1.5 kW air-cooled AC spindle, 10,000-24,000 rpm, ER11 collet, 80 mm dia x 205 mm, 4.35 kg.
Overview
The TS-21 is a 1.5 kW air-cooled spindle for routing and milling work that needs more power than the 800 W TS-19/TS-20 pair, while keeping the same ER11 collet and speed range.
It runs at 10,000-24,000 rpm and takes tooling through an ER11 collet. The body is 80 mm in diameter and 205 mm long, weighing 4.35 kg - noticeably larger than the 800 W spindles, since the extra power needs a bigger winding and frame to dissipate heat by air alone.
Power is 1.5 kW, drawn from a 220 V three-phase supply at 6 A through a variable frequency drive sized for the motor; the VFD's output frequency sets the running speed within the rated range.
Being air-cooled, it needs clear airflow around the body rather than a sealed housing. Where more power is needed in a larger collet, the TS-22 steps up to 2.2 kW with an ER16 collet in the same body diameter.

Questions
Same speed range as the 800 W TS-19/TS-20 but noticeably bigger — what am I actually getting for the extra size?
More power in the same collet — 1.5 kW instead of 800 W, still an ER11 collet and the same 10,000-24,000 rpm range. The larger body (80mm/205mm/4.35kg) is there because the extra power needs a bigger winding and frame to shed heat by air alone.
Given how much bigger this is, can I put it in a sealed housing now?
No — still air-cooled, so it needs clear airflow around the body rather than a sealed housing, same constraint as the smaller spindles in this range.
If I need more power still, and don't mind a bigger collet, what's the next step up?
The TS-22 — 2.2 kW with an ER16 collet, in the same body diameter as this one.
What tooling does the collet take?
ER11.
What does it need to run?
1.5 kW from a 220 V three-phase supply at 6 A, through a VFD.
