Medical miniature brushless motor

Abstract

The invention discloses a medical miniature brushless motor, which belongs to the technical field of motors and comprises a base fixedly mounted in a motor shell, a track assembly is arranged on the base, a power output assembly is slidably mounted on the track assembly and comprises a winding mounting cylinder, and the winding mounting cylinder is slidably mounted on the track assembly. A rotor and a winding coil are arranged in the winding installation cylinder, air outlet holes are formed in the winding installation cylinder, a damping assembly is further fixedly installed on the base and used for controlling the opening size of the air outlet holes, and then the damping effect is achieved through the counter-acting force of airflow. According to the invention, the brushless motor can automatically realize the functions of heat dissipation and shock absorption in the use process, dust in the motor can be removed under the condition that the motor is not disassembled, the operation is simple, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a medical miniature brushless motor. Background technique [0002] The brushless motor also includes a rotor and a stator. The structure of the brushless motor is opposite to that of the brushed motor; the rotor of the brushless motor is a coil winding, which is connected to the power output shaft, and the stator is a permanent magnet; the rotor of the brushless motor is a permanent magnet. The magnetic steel is connected to the output shaft together with the casing. The stator is a winding coil, and the commutation brush used by the brushed motor to alternately transform the electromagnetic field is removed, so it is called a brushless motor. When vibration occurs, the vibration of the motor will affect the stability of the output power. At the same time, the traditional motor needs to be disassembled after a period of use to remove the dust inside the motor. This operation is co...

Problems solved by technology

[0002] The brushless motor also includes a rotor and a stator. The structure of the brushless motor is opposite to that of the brushed motor; the rotor of the brushed motor is a coil winding, which is connected to the power output shaft, and the stator is a permanent magnet; Magnetic steel, together with the shell, is connected to the output shaft. The stator is the winding coil. The commutation brush used to alternately change the electromagnetic field of the brushed motor is removed, so it is called a brushless motor. Vibration occurs, and the vibration of the motor will affect the stability of the output power. At the same time, the traditional motor needs to be disassembled after a period of use to remove the dust inside the motor. This operation is complicated and reduces the production efficiency. The publication number is CN211296428U The Chinese utility model patent discloses a shock absorbing motor, including: a motor body and a bracket for supporting the motor body; the shock absorbing motor also includes a shock absorbing device for shock absorbing the motor body; the shock absorbing device includes: Shock block, shock mount, several shock absorbing springs, multiple connecting rods, multiple splints for clamping the motor body and clamp bands for binding multiple splints and the motor body into a whole; shock absorber Surrounding the shock-absorbing block in a ring shape; the shock-absorbing block is connected to the inner wall of the shock-absorbing frame through several shock-absorbing springs; the connecting rod is fixed to the outer wall of the shock-absorbing frame; the connecting rod passes through the splint; one end of the splint passes through the clamp belt Fixed to the motor body; the other end of the splint is connected to the connecting rod; the shock mount is set at one end of the motor body

Although this prior art has realized the damping effect of the motor, the purpose of damping is only to use the characteristics of the spring to complete, the working mode is single, the damping effect is limited, and the damping device is separated from the motor body, which is inconvenient to use. Based on the above Defects, the present invention provides a medical micro brushless motor, which can effectively solve the above technical problems
