The Relationship between Bypass Leakage and Minimum Stable Angular Speed of Swing Vane Motor

The internal leakage of the oscillating vane motor directly affects the output angular velocity;The Present Paper establishes the transfer function of the oscillating motor with the bypass leakage channel;In the process of establishing the system transfer function,taking the input flow of the motor working chamber as the input and the output angular velocity of the motor as the output,considering the bypass leakage model and the motor friction torque model,the expression of the minimum stable velocity of the motor was derived.By analyzing the influence of the parameters of the bypass leakage channel on the minimum stable velocity of the motor,the relationship between the minimum stable velocity of the motor and the parameters of the leakage channel inside the motor and the bypass leakage channel is given,and the calculation method of the input flow corresponding to the minimum stable running speed of the motor is proposed.
