Product User’s Manual – MOSPG30ExxxK
1.0 Introduction and Overview
Figure 1.0 DC geared motor with encoder and its removable cover
This document explains the general method to use the encoder for MOSPG30EXXXK. “XXX”
is referring to the gear ratio of Cytron’s SPG30 Geared Motor series which is either 20, 30, 60,
150*
, 200 or
300*
. This DC Geared Motor with Encoder is formed by a quadrature hall effect
encoder board which is designed to fit on the rear shaft of Cytron’s SPG30 Geared Motor series.
Two hall effect sensor are placed 90 degree apart to sense and produce two output A and B which
is 90 degree out of phase and allowing the direction of rotation to be determined. This encoder
provides 3 counts per revolution of the rear shaft. Please note that the encoder is mounted at the
rear shaft, the minimum resolution is depends on the motor’s gear ratio.
* The actual gear ratio for SPG30E150K is 120:1
* The actual gear ratio for SPG30E300K is 270:1
