Embodiment Construction
[0035] like figure 1 As shown, the five-degree-of-freedom magnetic levitation electric spindle 1 is mainly composed of a three-degree-of-freedom six-pole radial-axial hybrid magnetic bearing a, a two-degree-of-freedom six-pole radial-axial hybrid magnetic bearing b and a high-speed motor c; three-degree-of-freedom six The pole radial-axial hybrid magnetic bearing a, the two-degree-of-freedom six-pole radial hybrid magnetic bearing b and the high-speed motor c are coaxially installed in the sleeve n, and the three-degree-of-freedom six-pole radial-axial hybrid magnetic bearing a The two-degree-of-freedom six-pole radial hybrid magnetic bearing b and the center of the high-speed motor c share a rotating shaft s, and the two ends of the rotating shaft s are supported by a corresponding auxiliary bearing g1 and g2, and the auxiliary bearing g1 and g2 are respectively fixed on the corresponding ends Cover h1 and h2. The radial displacement sensors f1 and f2 are respectively fixed ...
