Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purpos...

Abstract

The invention provides a linear motor. The linear motor comprises a sliding mechanism, and a primary mechanism and a secondary mechanism which are arranged on the sliding mechanism at an interval, wherein the secondary mechanism comprises a first secondary unit and a second secondary unit which are arranged in parallel in the vertical direction, the first secondary unit comprises a first magnet yoke and first magnetic steel arranged on the first magnet yoke, and the second secondary unit comprises a second magnet yoke and second magnetic steel arranged on the second magnet yoke. The first magnet yoke and the second magnet yoke are provided with long shafts arranged in the moving direction of the sliding base and short shafts perpendicular to the long shafts, and the first magnetic steel inclines towards the moving direction of the sliding base relative to the short shafts; and the second magnetic steel inclines relative to the short shaft in a direction deviating from the moving direction of the sliding seat. According to the motor, a technical problem that the performance of the motor is affected due to bending moment generated between the rotor and the stator of the motor causedby inclination of the magnetic steel of the linear motor is solved.

Description

【Technical field】 [0001] The invention relates to the technical field of motors, in particular to a linear motor. 【Background technique】 [0002] As a zero-transmission driving mechanism, the linear motor does not require an intermediate transmission mechanism, and has the advantages of high precision, high dynamic response and high rigidity. In addition, with minimal mechanical losses due to no transmission wear, linear motors require low maintenance and have a long life. Therefore, the application of linear motors is becoming more and more extensive. [0003] Permanent magnet synchronous linear motors mostly use high-performance rare-earth magnets as the secondary, and steel sheet cores with slots as the primary to increase the output of the motor per unit volume, that is, the thrust density. It is precisely because of the existence of cogging that the air gap of the motor is uneven, causing thrust fluctuations, that is, cogging force. In addition to affecting the smoot...
