Speed/Voltage 3000-12000r/min 12V-3000 RPM24V-6000 RPM36V-9000 RPM48V-12000 RPM Air Cooling Methods This motor has quiet operation, small volume and high speed, and the rear end of the motor is reinforced with a cooling fan, which can be safely worked for a long time. ER16 Extension Rods and Collet The motor is equipped with ER16 extension rod and collet, which supports engraving wood/plastic/acrylic/ pvc/pcb/carbon fiber/density board and other materials.ER11 toolholder is equipped with 8mm colletThe clamping range of drill chuck is 1.5-10mm. The function of the line is equivalent to a switch, and the output voltage cannot be output when it is disconnected. As for the positive and negative wiring of the motor and the power supply, you can connect it at will. Because the motor supports reverse rotation, if you need the motor to rotate forward, just replace the interface. This power regulator supports both 110V and 220V, If users need 110V, please just adjust the power supply to 110V. 300W ER11 Spindle Kit 300W ER16 Spindle Kit 400W ER11 Spindle Kit 400W ER16 Spindle Kit 800W ER11 Spindle Kit 800W ER16 Spindle Kit Buying Options Add to Cart Buying Options Add to Cart Add to Cart Add to Cart Customer Reviews 3.0 out of 5 stars 2 3.0 out of 5 stars 2 5.0 out of 5 stars 1 — 3.3 out of 5 stars 26 3.3 out of 5 stars 3 Price — no data $117.70$117.70 — no data $97.00$97.00 $117.00$117.00 $119.00$119.00 Power 300W 300W 400W 400W 800W 800W Voltage 12-48VDC 12-48VDC 12-48VDC 12-48VDC 110V DC 110V DC Speed 3000-12000r/min 3000-12000r/min 3000-12000r/min 3000-12000r/min 5000-12000r/min 5000-12000r/min Torque 400mN.m 400mN.m 500mN.m 500mN.m 790mN.m 790mN.m Diameter 52mm 52mm 52mm 52mm 52mm 52mm Collet ER11 ER16 ER11 ER16 ER11 ER16 Runout off 0.01-0.04mm 0.01-0.04mm 0.01-0.03mm 0.01-0.03mm 0.01-0.03mm 0.01-0.03mm Cooling Methods Air Cooling Air Cooling Air Cooling Air Cooling Air Cooling Air Cooling
