Abstract—The driving capability of bladder power pump (BPP) obtain maximal ic driving force and optimal
is affectd by the control and structure parameters of the structure of the ic drive, it is quite essential to
ic drive of the BPP. To study the driving capability, analyze the relations between the ic driving force
a three-dimensional finite element model of the ic and the influence factors.
drive is built using finite element method (FEM). The driving
capability is investigated by means of the model, taking into There are several methods to analyze ic force,
account the control and structure parameters such as the exciting such as experience expressions, ic circuit partition,
current of , the number, interval size and initial numerical analysis, and so on [9]-[10]. The former two
angle of permanent s (PMs). The FEM analysis results methods are not suitable for the BPP with large air gap.
show that the driving capability is enhanced by paratively, the numerical analysis method is suitable and
increasing the exciting current of the and the more credible. ANSYS is a sort of popula
