SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING 惯性消 t Hydraulic motors possess an extremely high ratio of torque to inertia. Because of this, very little of the available torque is dissipated in accelerating the motor, most of the torque can be 除 applied directly to the load. Acceleration rates for unloaded hydraulic motors. for example, vary from about 0.3x105radians per second squared for larger sizes at 3000psi to 3. 4x10radians per second squared for smaller motors. No other transmission system produces motors having acceleration rates anywhere near these values. Higher supply pressures develop accordingly higher acceleration rates 加速度 Hydraulic motors develop no counter electro-motive force as do electrical motors There fore. the acceleration rate is essentially constant over their design speed ranges psi= pound per square inches每平方英寸磅SCIENCE AND TECHNOLOGY ENGLISH FOR MECHANICAL ENGINEERING Hydraulic motors possess an extremely high ratio of torque to inertia.

Acceleration rates for unloaded hydraulic motors, for example, vary from about 0.3105 radians per second squared for larger sizes at 3000psi to 3.4105 radians per second squared for smaller motors. No other transmission system produces motors having acceleration rates anywhere near these values. Higher supply pressures develop accordingly higher acceleration rates. Hydraulic motors develop no counter electro-motive force as do electrical motors. Therefore, the acceleration rate is essentially constant over their design speed ranges. 惯 性 消 除 加速度 psi=pound per square inches 每平方英寸磅
