A lubricant-supported electric motor includes a stator having a stator raceway and a rotor movable relative to the stator about an axis and having a rotor raceway spaced apart from the stator raceway to define a gap therebetween. A lubricant is disposed in the gap for supporting the rotor relative to the stator. The stator defines at least one hydrostatic support cavity radially recessed relative to the stator raceway and in fluid communication with the gap. The stator also defines a channel in fluid communication with the at least one hydrostatic support cavity for providing lubricant to the at least one hydrostatic support cavity and the gap. A flow restriction mechanism is disposed in fluid communication with the channel for controlling and balancing the supply and pressure of the lubricant in the hydrostatic support cavity.
一种润滑剂支撑电动机包含一定子及一转子,所述定子具有一定子滚道,所述转子可相对于所述定子绕一轴线移动且具有一转子滚道,所述转子滚道与所述定子滚道间隔设置以在其间定义一间隙。一润滑剂设置在所述间隙中,用于相对于所述定子支撑所述转子。所述定子定义出至少一个流体静力支撑腔,相对于所述定子滚道径向凹入并与所述间隙流体连通。所述定子也定义出与所述至少一个流体静力支撑腔流体连通的一通道,用于提供润滑剂到所述至少一个流体静力支撑腔和所述间隙。一流动限制机构设置成与所述通道流体连通,用于控制和平衡所述流体静力支撑腔中的所述润滑剂的供应和压力。
