Abstract

The invention provides an encoder, a motor and a driving system. The encoder is installed on the motor. The encoder comprises a code disc and magnetic steel or a magnetic ring, and the code disc and the magnetic steel or the magnetic ring are installed on a rotor of the motor and synchronously move along with the rotor; the circuit board comprises at least one magnetic induction module, at least one light induction module and a signal processing module, the magnetic induction module is arranged corresponding to the magnetic steel or the magnetic ring, and the light induction module is arranged corresponding to the code disc; the circuit board is fixedly connected with at least one first mounting part arranged on the encoder base; or the circuit board is fixedly connected with at least one second mounting part arranged on the encoder rear end cover; or the circuit board is fixedly connected with at least one third mounting part arranged on the rear end cover of the motor. The encoder provided by the invention solves the problem that in the prior art, an optomagnetic hybrid encoder measures position information through three magnetic induction chips, and the production cost is relatively high.

Description

Technical field [0001] The present invention relates to the field of encoders, and in particular, to an encoder, a motor, and a drive system. Background technique [0002] Encoder technology is widely used in the field of precision instrument control and position detection such as motor speed measurement and position detection, such as absolute encoders can be used to detect the number of rotation of the motor, the rotation direction, and the rotational position. [0003] With the advancement of technology, in order to meet the precision, stability and cost of control systems, the accuracy requirements and reliability requirements of the encoder are getting higher and higher, and the installation conditions of the encoder need to be lower to reduce Installation cost. [0004] In the high-precision absolute value encoder, it is made in two ways to obtain a high-precision absolute value, wherein the absolute value coded is a rough channel, and the relative position code is used as ...
