Problems solved by technology

At least one embodiment of the device requires that the middle part of the mover cannot directly install the output shaft, which is inconvenient to install, and the linear movement of the sleeve takes up a lot of axial space, which is not conducive to the miniaturization of the motor

Embodiment

[0025] A motor for a range hood, such as figure 1 As shown, the motor has a stator 1 and a rotor 2 rotatably supported in the stator 1. The stator 1 is provided with a magnetic conductive component 3, and the magnetic conductive component 3 can deform to change the motor constant of the motor. The coils are arranged radially on the stator 1 . Permanent magnets are arranged radially on the rotor 2 .

[0026] like figure 2 , 3 As shown, the deformation of the magnetically permeable component 3 can change the leakage flux, thereby changing the motor constant, taking into account both high torque and high rotational speed. The magnetic conductive assembly 3 includes a magnetic conductive cylinder 4 that surrounds the stator 1 and is coaxial with the stator 1. The magnetic conductive cylinder 4 includes a number of very narrow supporting pieces 5 arranged along the axial direction of the motor, and the supporting pieces 5 surround the magnetic conductive The cylinder 4 is arra...

Abstract

The invention discloses a motor used for range hoods, and aims to solve the problem that the current structure capable of adjusting the motor constant of the motor is relatively bloated and occupies a lot of space. The invention includes a stator and a rotor rotatably supported in the stator, and a magnetic conduction assembly is provided on the outer surface of the stator, and the magnetic conduction assembly can deform and change the motor constant of the motor. This structure realizes the change of the motor constant without occupying the axial direction, and takes into account both high speed and high torque at different stages of work, and the setting of cooling fins improves the heat dissipation capacity of the motor.

Description

technical field [0001] The present invention relates to the field of motors, and more particularly, to a motor used for a range hood. Background technique [0002] The motor constant, also known as the voltage constant or torque constant, mainly characterizes the electromechanical performance of the motor. In general, the motor constant is a fixed, machine-related quantity that can only be changed in so-called field weakening operation. However, only the motor constant can be reduced in field weakening operation. Depending on the size of the motor constant, the motor can produce a higher maximum speed or a higher maximum torque. The torque of an electric machine basically depends on the operating point at which it is set, that is, the torque is a function of the rotational speed. In a motor, the relationship between rotational speed and torque is described by the so-called motor constant (torque constant), and is usually a straight line with a slope. A larger motor const...
