Abstract
The present disclosure provides an absolute encoder capable of suppressing an increase in size while securing the resolution. An encoder includes a magnet rotating integrally with at least one rotary body and a plurality of rotary sensors detecting magnetic poles of the magnet to output detection signals having sinusoidal waveforms, each sinusoidal waveform having a different phase. The at least one rotary body includes a first rotary body rotating integrally with a main shaft and a third rotary body rotating together with the rotation of the first rotary body. The absolute encoder includes an angular sensor to detect the rotational angle of the first rotary body and the magnet is arranged in the third rotary body.
