主要优势 | Main disadvantages |
①Compact structure | ①The wear between the blade and the stator limits the increase in working pressure and rotational speed. |
② The outline size is small, and the inertia is smaller than that of a plunger motor. | ② Output torque is relatively small |
③ Low noise, small pulsation | ③Leaked relatively large |
④ Long lifespan | ④Poor pollution resistance |
⑤Low-speed performance is better than gear motors |
