A motor with overload protection structure

Abstract

The invention discloses a motor with an overload protection structure. A driving shaft drives an elastic element to realize rotation of an output shaft; and when the motor load exceeds the tension between the elastic element and the output shaft, the driving shaft only drives the elastic element to rotate, and the output shaft stops rotating at the current moment so as to protect the motor. The motor provided by the invention has the advantages of low manufacturing cost, small size and easy production and manufacturing; meanwhile, the tension between the elastic element and the output shaft can be controlled by adjusting the wire diameter and the diameter of the elastic element; and therefore, motors with the overload protection structures of different specifications can be provided.

Description

technical field [0001] The invention relates to a motor, in particular to a motor with an overload protection structure. Background technique [0002] With the continuous development of the machinery industry, the use of motors is becoming more and more extensive, and it is gradually replacing manual operations to complete various projects. However, in actual use, the phenomenon of motor overload often occurs. Once the motor is overloaded, the motor is strongly and continuously driven because it does not receive an overload signal, but in fact it cannot work with the workpiece. Therefore, the motor will heat up because it cannot be driven normally, and the time course will cause the motor to burn out. [0003] In the prior art, the motor avoids the overload of the motor by additionally setting an overload protection circuit or an overload protection structure, but these structures require more manufacturing costs, and correspondingly increase the storage space for setting t...

However, in the actual use process, the phenomenon of motor overload often occurs. Once the motor is overloaded, the motor is driving strongly and continuously because it does not receive an overload signal, but in fact it cannot move the workpiece to work.

Therefore, the motor will heat up because it cannot be driven normally, and the time course will cause the motor to burn out

[0003] In the prior art, the motor avoids the overload of the motor by additionally setting an overload protection circuit or an overload protection structure, but these structures require more manufacturing costs, and correspondingly increase the storage space for setting these structures
