DIRECT DRIVE SYSTEM

WIPO Patent Application WO/2024/000682

A1

Provided in the utility model is a direct drive system. The direct drive system comprises: a base, the base being provided with a guide rail; a sliding block, the sliding block being slidably arranged on the guide rail; a rotor assembly and a stator assembly, the rotor assembly comprising a rotor and magnetic steel arranged on the inner side wall of the rotor, the rotor being arranged on the sliding block, the stator assembly comprising a stator supporting seat and a stator connected to the stator supporting seat, the stator supporting seat being arranged on the base, and the stator being inserted into the rotor and being arranged opposite to the magnetic steel in a spaced apart manner; and a blocking member, the first end of the blocking member being connected to one side of the base facing away from the stator supporting seat, and the second end of the blocking member obliquely extending in a direction of getting close to the stator and being spaced apart with the sliding block. By means of the arranged blocking member, foreign matters can be effectively prevented from falling onto the guide rail from above, so that a situation of the sliding block being jammed by foreign matters on the guide rail is avoided, thereby achieving a good protection effect, and effectively increasing the operation precision and prolonging the service life of the guide rail.
