Description

Technical Field

[0001] The utility model relates to the field of inserting tube fixtures for lead wires, and particularly relates to a three-phase lead wire inserting tube fixture for motors. Background Technique

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses a current-carrying coil to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric driving rotating torque. Motors are divided into DC motors and AC motors according to the different power supplies used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. A motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying wire in a magnetic field is related to the direction of the current and the direction of the magnetic induction line. The working principle of a motor is the force exerted by a magnetic field on a current, which causes the motor to rotate.

[0003] With the booming development of the motor manufacturing industry and the increasing refinement of industry division of labor, from the production of stators and rotors to the final assembly of motor products, they are not completed in the same place. Usually, the stator lead wires are divided into three phases: U, V, and W. In order to better distinguish which wire is U, which is V, and which is W, sleeves of corresponding lead wire colors are usually selected. For example, U is black, V is red, and W is white. During the operation process, the entire stator is often scrapped due to the incorrect insertion of the three-phase UVW corresponding to the sleeve colors, which will cause the stator to fail to work or work abnormally, thus bringing huge losses to the company. To ensure that the three-phase lead wires of each stator are clear, reduce the error phenomenon, and save the time-consuming process of distinguishing which wire is U, which is V, and which is W.
