主要优势 | Main Disadvantages |
① Axial dimensions are relatively small ②Large displacement, low speed ③ Low-speed stability is good, can operate steadily below 10r/min, and can be as low as 1.5r/min. ④Output torque is large, reaching several thousand or even tens of thousands of Newton·meters. ⑤ Can be directly linked to the movable working mechanism without the need for a deceleration device | ①Large radial size ②Complex structure, larger volume, Low power density |
