New Square 3KW Air-cooled Spindle Motor ER20 220V 300Hz For CNC Milling Router Package include: 1 x 3KW Square Air cooled spindle motor ER20 ( 18000rpm, 4bearing, 300Hz, 89x98x300mm ) 3KW Air-cooled Spindle Motor 220V 300Hz 18000rpm ER20 3.0KW AIR-COOLED SPINDLE MOTOR ENGRAVING MILLING GRIND Specification: Material: Stainless Steel Size: 89x98x300mm Power: 3Kw Voltage: 220 Current: 10A Frequency: 300Hz Speed: 18000rpm Cooling: Air-cooled Runout off: Less than 0.05mm Precision tapered bore: Less than 0.025mm Bearing Lubrication: Grease Collet size: ER20 Bearings: 4 bearings(C7005x2 + C7002x2),P4 class, Angular contact bearings Net Weight: 7.0kg Power supply interface: Professional aviation Interface, Interface 1234 marked 123 respectively connected to the inverter output end of the (U, V, W), 4 ground wire this interface must be safe ground. Main application: Wood, Aluminum, Stone, metal, glass, PVC industry 1. Structural features 1) High speed electric main bearing all adopt the Ceramic bearing, axis sets of loading, Improve spindle in the high-speed rotation supporting stiffness and precision grinding. 2) Before driving, rotation of the shaft by hand.Spindle high speed rotation caused by temperature rise, use of cooling liquid circulating system to eliminate. 2. Instructions for use 1) In use, must first connect the cooling water pipe, make spindle connect cooling water and then start. 2) Before driving, turned by hand spindle. If sensory block is not flexible, you should troubleshoot, and then check the direction of rotation of the spindle from the spindle end to see if the match should rotate counterclockwise power wiring should be changed to make it consistent. 3) Before driving, cooling water for grinding workpiece can’t be in the front end of the spindle cover, to prevent the front bearing cover slot inlet burning motor and bearing. the motor must not enter the water, after turned on of the motor, when you live in grinding the workpiece to open the grinding of workpieces coolant. First off the workpiece coolant shutdown, and then close the spindle motor. 3. Maintenance and Service 1) Motorized spindle by medium frequency power supply rated voltage, frequency should be consistent with electric spindle technology parameters, motorized spindle rotational speed can change the frequency to adjust, also directly proportional voltage change. 2) When the spindle is temporarily not in use, should use compressed air to blow the coolant water,to avoid rusting, plug the hole. Spindle surface should be coated with anti rust oil. The shaft end protecting device, placed in dry place. 3) If replacement the spindle of bearings, best professional and technical personnel from the replacement. Use special tools, stator coil does not to be removed. 1.We accept Paypal for payment.all Paypal must be confirmed (shipping and billing address must match and correct) 2.Please pay within 3 days of order. 1.
