Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor with real-time digital display of current and voltage overload alarm. Background Technique

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses a current-carrying coil (i.e., the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric dynamic 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 (the rotational speed of the stator magnetic field of the motor does not remain synchronous with the rotational speed of the rotor). A motor mainly consists of a stator and a rotor. The direction of the force on the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line (magnetic field direction). The working principle of the motor is the action of the magnetic field on the current, which makes the motor rotate.

[0003] During the use of existing motors, in order to ensure the safety of motor operation, most of them are equipped with overload alarms. Most of the existing overload alarms are fixed by bolts, and it is very troublesome to disassemble and install them. At the same time, the motor will vibrate during operation. After a long time, the electronic components inside the overload alarm will be damaged, affecting the service life. Content of the Utility Model
