A motor with high circuit board safety

Abstract

The invention relates to the field of motors, and in particular relates to a motor having high circuit board security. The motor comprises a stator, a rotor and a rotating shaft, wherein the rotor sleeves in the stator; the rotating shaft is arranged on the rotor in a penetrating manner; the motor further comprises a shell and a base, wherein the shell and the base are mutually adapted; the shell sleeves the shell end face on the stator and is provided with a ventilation hole; a locating installation hole column is arranged in the centre of the base; a circuit board is arranged outside the base in a bridging manner; a drainage fan is fixedly arranged on the rotating shaft and outside the shell end face; a plastic package body is packaged outside the stator; a plastic package enhanced connection ring arranged to lean on the side wall surface of the shell is arranged on the plastic package body towards the end face at one side of the base in an integral connection manner; an airflow at the rear end of the circuit board is fed into the motor through the circuit board and the ventilation hole on the bottom plate; same, an airflow between the circuit board and the bottom plate is fed into the motor through the ventilation hole on the bottom plate; and then, heat in the motor is absorbed and rapidly output from the motor through the ventilation hole on an inclined enhancement hole arrangement groove wall. The whole motor has the advantages of being high in integrality, compact in structure, convenient to assemble and disassemble, low in cost, high in strength, good in stability and low in noise.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor with high circuit board safety. Background technique [0002] At present, motors are widely used in electronics and automation equipment industries. During the operation of the motor, a large current is injected into the coil of the stator, so that the coil generates a large amount of heat, and the heat generated continues to accumulate with the growth of time in the future, making the temperature inside the motor gradually increase, thus affecting the internal parts of the motor. Working performance also has a great impact on the service life of each part, especially the impact on the circuit board is more obvious, it is easier to damage the electronic components on the circuit board, and even cause the circuit board to burn out. Existing motors with heat dissipation structures are only suitable for motors with inner stator and outer rotor structures, and are not effective for out...

Problems solved by technology

During the operation of the motor, a large current is injected into the coil of the stator, so that the coil generates a large amount of heat, and the heat generated continues to accumulate with the growth of time in the future, which makes the temperature inside the motor gradually increase, thus affecting the internal parts of the motor. Working performance also has a great impact on the service life of each part, especially the impact on the circuit board is more obvious, it is easier to damage the electronic components on the circuit board, and even cause the circuit board to burn out

Some existing motors with heat dissipation structure are only suitable for motors with inner stator and outer rotor structure, and the effect is not good for the structure of outer stator stator and rotor
