EEJA spindle motor Advantages:
● Positive air pressure inside is applied to seal the products so no foreign materials can find ways to enter the spindle bodies.
● Water route is designed inside for cooling and no over heat will happen in working.
● The bearings are from famous brand in Japan or Germany.
●The steel of shaft and other key components are from Japan.
●The motor wires are well treated for high property of electrical resistance.
● All these result in high quality of long life, precision, high speed, low shaft run-out, etc.
●The whole manufacturing processes have been designed, tried and improved again and again to meet the high precision requirement like the master shaft diameter in the tolerance of +/-0.001mm.
●World class equipment is used for manufacturing and testing. Clean room is used for assembly.
●The team of designing and manufacturing are well educated, trained and have built up their robust experience in their work.
