Limiting tube-shaped motor for multiple parallel-connection machinery

The utility model discloses a limiting tube-shaped motor for multiple parallel-connection machinery, which comprises a plurality of tube-shaped motors which are arranged in parallel, are respectively provided with a limiting switch and are connected to a same control end together. The limiting tube-shaped motor is characterized in that crosstalk preventing devices are arranged at the front or the back of the limiting switches, and each crosstalk preventing device comprises a relay which is controlled by a control module. Therefore, the plurality of tube-shaped motors can be stopped simultaneously so as to ensure the effective parallel connection of the plurality of tube-shaped motors.
