Further, above-mentioned bearing is seal angle contact ball bearing, and above-mentioned bearing is provided with sealing ring and ceramic balls.
Further, the both sides of said stator coil also scribble water-proof silica-gel layer.
Further, above-mentioned front axle gland is enclosed within the outside of front nut, and above-mentioned dust cap is fixed on shell, the inwall of above-mentioned dust cap by above-mentioned front nut compressing in front axle gland.
Further, the side of above-mentioned front nut is provided with three annular projection progressively raised by outside to axle center height.
Further, above-mentioned dust cap inwall is provided with two juts be slit into by a sunk part, above-mentioned jut is also arranged with two location counterbores.
Further, be provided with the depressed part corresponding with three annular projection on above-mentioned front nut in above-mentioned front axle gland, the outside of above-mentioned outermost depressed part is provided with multiple positioning through hole, multiple screwed hole, multiple location counterbore.
Compared with prior art, provided by the utility model without mist of oil energy-conserving and environment-protective electro spindle, without the need to configuring oil mist lubrication device and air compressor, have without oil-break, main shaft operates steadily, and work-yard is without oil pollution, save energy consumption, maintenance number of times is few, the advantage that maintenance cost is low.
