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

Features of Quadrature Hall Effect Encoder:

Operating voltage: 4.5 V to 5.5 V

Two digital outputs ( Quadrature waveform )

Small in size and light in weight

Resolution: 3 pulses per rear shaft revolution, single channel output.

60 counts per main shaft revolution for 1:20 geared motor

90 counts per main shaft revolution for 1:30 geared motor

180 counts per main shaft revolution for 1:60 geared motor

450 360

 counts per main shaft revolution for 1:120 geared motor (SPG30E­150K)

600 counts per main shaft revolution for 1:200 geared motor

900 810

 counts per main shaft revolution for 1:270 geared motor (SPG30E­300K)
