Problems solved by technology

However, this kind of structure is difficult to stack and process, which increases the processing cost.
In addition, since the silicon steel sheets that make up the inner stator are rectangular silicon steel sheets with uniform thickness, there must be gaps between the silicon steel sheets on the outer circumference of the inner stator, which will increase the magnetic resistance and reduce the efficiency of the motor.

Embodiment Construction

[0020] figure 1 It is a longitudinal section view of a linear vibration motor applied to a compressor in the prior art. As shown in the figure, the linear vibration motor is mainly composed of the following structures: stator winding 1, outer stator core 2, spring 3, inner stator core 7, permanent magnet 8, piston 13, permanent magnet support 14. The winding is embedded in the outer stator core and is a cake winding. The outer stator core is assembled from many small stator core blocks, and the outer stator punching pieces that form the small core blocks are in the shape of "C" ( figure 1 The C-shaped iron core cannot be seen in the middle). The inner stator is a radial structure with tight inside and loose outside (such as figure 2 As shown), the motor mover is composed of permanent magnets and non-magnetic permanent magnet brackets.

[0021] Different from the prior art, the present invention provides a moving magnet transverse magnetic flux linear vibration motor with ...

Abstract

The invention discloses a moving-magnet type transverse flux linear oscillatory motor for a direct-drive compressor, which comprises a rotor component and stator components which are matched with each other. In the motor, a transverse magnetic circuit structure is adopted to ensure that the motion directions of a magnetic circuit and the motor are in a perpendicular relation, thus the internal and external stators of the motor can both adopt an internal and external stator structure of an ordinary electric rotating motor and are stacked up along an axial direction. The moving-magnet type transverse flux linear oscillatory motor has the advantages of convenient processing, higher efficiency, small magnetic resistance, smooth output force curve, and the like and is easy to realize high frequency reciprocating oscillation with high thrust and large amplitude.

Description

technical field [0001] The invention relates to the field of vibrating motors, in particular to a vibrating linear motor with permanent magnets. Background technique [0002] The linear vibration motor can generate high-frequency reciprocating linear motion, which can directly replace the existing "rotary motor + crank shaft" drive system, thereby reducing transmission loss, reducing noise, and improving system efficiency and reliability. Therefore, the linear vibration motor can be widely used in occasions requiring high-frequency reciprocating motion, such as compressors and other fields. [0003] Most of the permanent magnet linear vibration motors used for direct drive compressors now adopt the "C" type outer stator structure, figure 1 A longitudinal section of the structure is given. As shown in the figure, the linear vibration motor is mainly composed of the following structures: stator winding, outer stator core, spring, inner stator core, permanent magnet, piston, ...
