气动马达是一种将空气压缩机的压缩气体转换成旋转机械能的原动机。它具有不同于电动机、液压马达、内燃机等原动机的工作特性。因为气马达的工作介质是气体,其弹性比任何固体和液体都大,所以气马达的工作特性较软,输出扭矩及转速能自动地随外负荷的变化而改变,如当负荷急剧增大或 An air motor is a prime mover that converts the compressed air of an air compressor into rotational mechanical energy. It has different from the motor, hydraulic motor, internal combustion engine and other prime mover operating characteristics. Because the gas motor working medium is gas, its flexibility than any solid and liquid are large, so the working characteristics of the gas motor is relatively soft, the output torque and speed can automatically change with the external load changes, such as when the load increases sharply or
