Abstract EN
This paper presents an improved dynamic model for unbalanced high speed motorized spindles.
The proposed model includes a Hertz contact force model which takes into the internal clearance and an unbalanced electromagnetic force model based on the energy of the air magnetic field.
The nonlinear characteristic of the model is analysed by Lyapunov stability theory and numerical analysis to study the dynamic properties of the spindle system.
Finally, a dynamic operating test is carried out on a DX100A-24000/20-type motorized spindle.
The good agreement between the numerical solutions and the experimental data indicates that the proposed model is capable of accurately predicting the dynamic properties of motorized spindles.
The influence of the unbalanced magnetic force on the system is studied, and the sensitivities of the system parameters to the critical speed of the system are obtained.
These conclusions are useful for the dynamic design of high speed motorized spindles.
