Encoder mounting structure and motor

Abstract

The invention relates to an encoder, and the invention discloses an encoder mounting structure. The encoder mounting structure comprises an encoder stator (1), an encoder rotor (2) and an encoder mounting plate (3), and the encoder rotor (2) is mounted on a motor mandrel through a mounting through hole in the encoder mounting plate (3); and the encoder rotor (2) is located in a cavity defined by the encoder stator (1) and the encoder installation plate (3), and the installation end of the encoder stator (1) is connected with the encoder installation plate (3) through a limiting structure so that the encoder stator (1) can be clamped, sealed and fixed to the encoder installation plate (3). The invention also discloses a motor. According to the invention, miniaturization of the motor is facilitated, the sealing performance of the motor can be ensured, and a high IP protection grade is realized.

Description

technical field [0001] The present invention relates to an encoder, in particular to an encoder installation structure, and also to a motor. Background technique [0002] With the continuous development of technology, industrial automation, robotics and other fields have increasingly stringent requirements on the length of motors. Under the premise of equal power, the overall size of motors is required to be continuously reduced, and the development of motor miniaturization has become a trend. [0003] As an important part of the motor, the encoder's size and installation method directly affect the IP protection level and body length of the motor. [0004] There are mainly two ways of assembling the existing encoders. The first way of assembling is to fix the encoder mounting plate 2a from radial locking screws, such as figure 1 and figure 2 , after the encoder stator 1a is inserted into the raised part of the encoder mounting plate 2a, the encoder is fixed by locking the...

Problems solved by technology

[0005] The first radial assembly method is not conducive to reducing the axial size of the encoder, making the length of the motor body too long; the second axial assembly method is likely to cause poor sealing of the motor, resulting in a low IP protection level of the motor, for example At present, the 40-frame series on the market adopts this method to assemble the motor with an encoder. Due to the large size of the encoder, it is easy to cause poor sealing of the motor, resulting in a low IP protection level of the motor, which cannot meet the requirements of other power segments on the market. IP65 and above protection level
