The utility model is mainly characterized in that a grating disk seat is separated from a motor body, a user shaft is connected with the grating disk seat on which a grating disk is installed, and an optoelectronic assembly is tightly fixed on a circuit board which is fixed to the motor body. The photoelectric axial angle encoder has advantages that the structure is simple, reasonable and compact; due to the adoption of a separated ultrathin structure, the axial dimensions of products are reduced; users can quickly install and use the encoder without the need of using special tools for adjustment; the adoption of a separated structure of a U-shaped slot of the circuit board makes the installation more convenient, the cost lower and the performance-price higher, which is more favorable for mass production and assembly.
Description
Technical field
The utility model relates to a kind of rotor magnetic pole position signal optical electric axial angle encoder, specifically is applied to motor servo system and automatic control system as detecting element or feedback element, belongs to a kind of novel displacement and angular transducer.
Background technology
Optical electric axial angle encoder is as a kind of sensor, and main the application progressively is diffused into civilian industry department by defence and military department.As be diffused into the application on numerically-controlled machine, robot, motor by application on military vehicle radar, artillery command instrument, aerospacecraft.Before the utility model was made, in prior art, former AC and DC servo electrical machinery system detected for realization speed ring, position ring, and except that adopting corresponding sensor, its rotor magnetic pole position detects other sensors such as general employing Hall.Speed ring had appearred doing afterwards, position ring detects the optical electric axial angle encoder that can detect the rotor position of magnetic pole again, optical electric axial angle encoder mainly adopts axle to fix by bearing, main body and with wiring board.But, can only be applied to industries such as numerically-controlled machine because its complex structure adopts the restriction of components and parts and configuration.Because of the particularly axial dimension restriction of restriction of the AC servo motor length of shaft structure of sewing machine and use thereof, general optical electric axial angle encoder axial dimension is bigger than normal, can not be applied on the sewing machine servomotor.
Technology contents
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; The product axial dimension is reduced greatly, the optical electric axial angle encoder that the user need not to use speciality tool and adjusts the rotor magnetic pole position signal that just can install and use rapidly.
Main solution of the present utility model is achieved in that
The utility model mainly adopts grating dish seat 4 and motor main body 1 isolating construction, and user's axle is connected with grating dish seat 4, and grating dish 3 is installed on grating dish seat 4, and photoelectric subassembly 2 is fastened on the circuit board 6, and circuit board 6 is fixing with motor main body 1.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to adopted the superthin structure separate design, the product axial dimension is reduced greatly, the user need not to use speciality tool and adjusts and just can install and use rapidly, and adopted the structure of circuit board " U " shape groove, make easier for installation, low-cost, high performance-price ratio more help large batch of production and assembly.
