Abstract The heavy drive dynamic system scheme of crank mechanical servo press is elaborated. Considering the particularity of transient heavy load of the press during stamping process, the theoretical analysis on parameters calculation formula about the permanent magnet synchronous motor(PMSM) and capacitance value of the capacitor group is carried out separately , and the approximate analytic expression is given. Taking a 80ton crank mechanical press as an application object, and according to the value from the calculated of theoretical formula, the hardware device of capacitor group energy storage is designed, and the PMSM drive servo system applied in the servo press is also developed. Taking the hydraulic accumulator as the loading object, the experiment was carried out. The experimental results prove that the formula of parameters analysis is reasonable, which provides the theoretical reference for the development and optimization of this servo-type press.
