Abstract

This utility model relates to the field of motor technology, specifically a multi-group Hall effect DC linear motor. The utility model includes a DC linear motor mechanism, which also includes a motor housing. A fixing sleeve is fixedly sleeved on the outer side of one end of the motor housing. A connecting block is fixedly connected to the outer wall of the fixing sleeve, and a fixing groove is formed inside one side of the fixing sleeve. This utility model, through the shielding grooves inside the first and second shielding plates, can tightly wrap the external connecting wires, forming an effective electromagnetic shielding structure. This design can significantly reduce the radiation impact of external electromagnetic interference sources on the connecting wires, avoid interference with the Hall effect sensors of the DC linear motor, further enhance the electromagnetic isolation effect, ensure the stability and accuracy of signal transmission, prevent the DC linear motor from receiving incorrect position and speed information, thus affecting control accuracy and reducing problems such as inaccurate positioning and speed fluctuations.
