Description

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] At present, low-voltage DC integrated servo motors have been applied to many fields, especially some occasions with high requirements on space and drivers. However, in some specific occasions, the current market standard low-voltage DC integrated servo motors have radial wiring, and the cable's turning radius makes the overall size still relatively large after installation. Moreover, radially-outlet cables are not convenient to fix, resulting in installation difficulties and easy damage to the cables. At the same time, the standard products have many connection terminals and interfaces, and the length and radial dimensions are relatively large. In order to reduce the number of terminals and the installation space of the dip switch, retain the input and communication interfaces, and directly provide power to the input peripherals in some specific occasions, it is particularly necessary to develop an axially-outlet integrated servo motor.
