Also, when the encoder fails, a new encoder for replacement is prepared and installed, but at this time, when the stator and the rotor are in a specific positional relationship, the position information of the new encoder is adjusted and assembled so that the position information of the new encoder is at the original position. Some motors and new encoders take time to operate

Embodiment Construction

[0042] Hereinafter, a motor and a motor with an encoder to which the present invention is applied will be described with reference to the drawings. figure 1 It is a cross-sectional view in the direction of the rotation axis L of the encoder motor 1 having the motor 2 according to the present invention, figure 2 It is an exploded perspective view of a motor with an encoder. In this specification, the side where the output shaft 34 of the motor with encoder 1 protrudes from one side in the direction of the rotation axis L of the motor with encoder 1 and the other side is defined as the output side L1, and the side protruding from the output shaft 34 is defined as the output side L1. The side opposite to the output side L2. Moreover, let two directions orthogonal to the rotation axis L be an X direction and a Y direction. In the installation posture of the encoder-equipped motor 1 , the X direction is the vertical direction, and the Y direction is the horizontal direction. Th...

Abstract

The present invention relates to a motor and an encoder motor, a method of manufacturing an encoder motor, and an encoder replacement method with an encoder motor. In encoder motor, the positioning of the encoder and motor in the direction of rotation can be easily and correctly performed. The encoder (3) in the motor with encoder (1) is detachable with respect to the motor (2). A positioning pin (70) fitted to a recess (80) provided in the encoder is provided in the motor, and a moving member (72) formed with a positioning pin is capable of adjusting the position in the circumferential direction. The main motor (200) and the main encoder (300) are used in the manufacture of an encoder motor. The motor (2) for mass production adjusts the position of the positioning pin by the main encoder when the main motor is in the motor locked state, so that the position information of the main encoder is at the home position. The encoder 3) Correction of position information with main motor and assemble them to complete encoder motor (1).

Description

technical field [0001] The invention relates to a motor with an encoder, in particular to a motor with a detachable encoder, a motor with an encoder, a manufacturing method of the motor with an encoder, and an encoder replacement method. Background technique [0002] Conventionally, a motor with an encoder is used in which an encoder is attached to one axial end of the motor. A motor with an encoder is assembled and adjusted so that the position information of the encoder becomes the origin position when the stator and the rotor are in a specific positional relationship within the motor. When the encoder is detachable from the motor, if the relative rotational position of the encoder to the motor deviates when the encoder is detached, the position of the origin of the encoder deviates. Also, when the encoder fails, a new encoder for replacement is prepared and installed, but at this time, when the stator and the rotor are in a specific positional relationship, the position ...
