Abstract :
The size of Motor spindle air-gap, which directly affects electric spindle runtime of various performance indicators, is one of the most important parameters of Motor spindle design and optimization process. This paper takes a 15KW high-speed electric spindle as an example, using the finite element analysis method establishes two-dimensional model and carries out a simulation research on different size of empty load harmonic air-gap flux density and harmonic flux density on air-gap eccentric. It gets the influence of air-gap changes on electric spindle magnetic field and confirms the best electric spindle air-gap scope laying the foundation for further optimization of motor spindle.
