Description

Technical Field

[0001] The present invention relates to the field of direct drive motors, and in particular to a general direct drive motor device. Background Art

[0002] A direct drive motor is a motor technology that can directly drive a load. It directly couples or connects a new type of rotary motor or linear motor to the driven load to achieve drive without intermediate transmission devices such as gears, belts, or chains. According to different motion forms, direct drive motors can be divided into two categories: rotary direct drive motors and linear direct drive motors. A linear direct drive motor, that is, a linear motor, is a motor that directly drives a load to perform linear motion.

[0003] For related technologies, reference can be made to the Chinese invention patent with the publication number CN118677139B, which discloses a linear motor module, including a base, a stator, a guide rail, a mover seat, a mover, and a cleaning component arranged above the base; the cleaning component includes a plurality of dust suction covers, a limiting frame is fixedly connected to one side wall of the base, a sliding frame is slidably connected in the limiting frame, a side plate is fixedly connected to the other side wall of the base, a drag chain is fixedly connected between the side plate and the mover seat through a connecting plate, the dust suction covers are arranged above the base and the drag chain, the tops of the plurality of dust suction covers are connected and fixedly connected with an air duct, the air duct passes through the sliding frame and is connected and fixedly connected with a fan, a dust suction pipe is connected and fixedly connected to the fan, the dust suction pipe is externally connected to a dust collection box, and a magnetic attraction component is arranged on the sliding frame. The magnetic attraction component includes a second electromagnetic block fixedly connected to the sliding frame, and a first electromagnetic block is fixedly connected to the side wall of the connecting plate close to the mover seat.
