Advanced dynamic balance technogy We adopt innovative & advanced dynamic balancing technology that effectively reduce the noise and increase stability in the working process. 3 times longer working life We use 4pcs upgraded of superior durability steel bearings and all copper lengthening coil of rotor for spindle motor. In normal case, the working life of our spindle motor can reach 2 years for 8 hours/day. Easy and fast to assemble There are 4 pins "1,2,3,4" on aviation connector. "1,2,3 " connect to "U,V.W" of VFD , "4" connects to ground. We offer pre-soldered wire with aviation connector that will be easy and fast to connect our spindle motor with VFD. High quality compact VFD 110V, 1.5KW, 400HZ VFD(Inverter). It is single phase(input), 3 phase (output). The VFD had been pre-programmed for basic parameters , you don't need to make extra setting up. Our VFD is enable motor to achieve high torque in low speed rotation.
