Abstract
The utility model discloses a rear-end assembled coder which is a magnetic rotation coder. The rear-end assembled coder comprises a subpanel and a circuit board, wherein the circuit board is arranged on the inner panel surface of the subpanel; the circuit board is provided with a coding chip; and the subpanel is provided with a connecting mechanism connected with the rear end cover of the motor rotor. The rear-end assembled coder overcomes various defects of the traditional coders and is easy to install and disassemble. As the magnitude of the torque, borne by the rear-end assembled coder, is determined by the mounting position, the service life is greatly prolonged. Compared with a potentiometer coder, the rear-end assembled coder has long service life by adopting the magnetic rotation coder. Compared with an optical coder, the rear-end assembled coder has outstanding economy and a wide applicable range. In addition, the utility model also discloses a motor of the rear-end assembled coder.
Description
Technical field
The utility model relates to a kind of encoder that can be installed in motor rear end part, also relates to a kind of motor that is equipped with encoder in rearward end simultaneously.
Background technology
Motor encoder is a kind of transducer that the geometry of machinery displacement on the motor output revolving shaft is converted to pulse or digital quantity by conversion.According to detecting principle, encoder can be divided into optical profile type, magnetic-type, induction type and condenser type, according to its scale method and signal output form, can be divided into increment type, absolute type and hybrid three kinds.Can be divided into contact and contactless two kinds according to the playback mode encoder. contact adopts brush output, and the contactless senser of accepting is light-sensitive element or magneto sensor.
In the motor encoder field, the mounting means of current encoder device is to adopt mechanical system to be fixed in the rotating shaft of motor encoder, and this scheme not only mounts and dismounts difficulty, and when motor bears than high pulling torque, encoder damages easily, does not possess performance advantage.
Summary of the invention
In view of this, one of the purpose of this utility model provides a kind of encoder that can assemble at motor rear end part, and this scheme is easy to removal and installation, and product has longer useful life; Two of the purpose of this utility model provides a kind of motor of rear end assembling encoder.
One of the purpose of this utility model is achieved through the following technical solutions:
This rear end assembled encoder, comprise magnet steel, mechanical tray and electronic mechanism are installed, magnet steel is assemblied on the magnet steel stand on the machine shaft, electronic mechanism is fixed on the interior card of tray, electronic mechanism is provided with coding chip, and electronic mechanism is the rotating magnetic field signal transition that the magnet steel rotation produces the increment type code signal.
Further, described rear end assembled encoder also comprises signal connecting line, and described signal connecting line and circuit board electrically connect back card outside mounting disc and draw;
Further, described bindiny mechanism is the combination of screw screw.
Two of the purpose of this utility model is achieved through the following technical solutions:
The motor of this rear end assembling encoder comprises foregoing rear end assembled encoder, and described rear end assembled encoder is arranged on the rear end cap of rotor.
Further, the rear end cap of described motor by bearing fixing on the rear end face of rotor;
Further, the rear end face of described rotor is provided with magnet steel seat, and described magnet steel seat is provided with magnetic steel ingot.
The beneficial effects of the utility model are:
1. encoder of the present utility model has overcome the drawback that the conventional mounting mode is brought, and its installation and removal are more easy, because the installation site has determined it not need to bear than high pulling torque, prolonged its useful life greatly;
2. the utility model adopts magnetic rotary encoder, owing to there is not mechanical contact, compare with the potentiometer encoder, its longer service life is compared with optical encoder, because the influence that not degraded by LED, when having improved resolution, economy is more outstanding, and magnetic rotary encoder can also be worked in the temperature range of-55 degree ~+125 degree simultaneously, and accommodation is wider.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
