Anti-electromagnetic interference micro motor shielding and noise reduction device

Abstract

The utility model relates to the technical field of micro motor, and disclose an anti -electromagnetic interference micro motor shielding noise reduction device, including micro motor body and mounting seat, the mounting seat is away from the one end of micro motor body and is inserted with at least two plug -in board, the both ends fixed mounting of mounting seat are away from the soundproof board of micro motor body, the soundproof board is close to the one end fixed mounting of micro motor body output and has the mounting ear hang, the soundproof board is away from the one end inserted with the shielding frame of mounting seat. This anti -electromagnetic interference micro motor shielding noise reduction device, through the arc -shaped clamping groove one sticking to the outer contour of micro motor body, cooperate with the close adhesion of upper clamping groove two and mounting seat, can form the effect of double positioning when installing soundproof board, can be convenient for the quick installation of soundproof board, and also not prone to shaking in the process of installation, thereby being convenient for subsequent maintenance and replacement, improve the practicability of overall shielding noise reduction device.
