EMG49, mounting bracket and wheel specification 

The EMG49 (encoder, motor, gearbox 49:1) is a 24v motor fully equipped with encoders and a 49:1 reduction gearbox. It is ideal for medium to large robotic applications, providing cost effective drive and feedback for the user. It also includes a standard noise suppression capacitor across the motor windings.

Motor Characteristics



Motor power is connected with a two way 3.96mm pitch terminal Excon type 3961 and has 300mm of cable as standard.

Black (1) - Motor
Red (2) + Motor

The encoders connect using a  4 way JST  connector (part no PHR-4) at the end of approx 300mm of cable as standard. 
The connections are:

Wire colour Connection
Purple (1) Hall Sensor B Vout
Blue (2) Hall sensor A Vout
Green (3) Hall sensor ground
Brown (4) Hall sensor Vcc

Wires are the colours from the actual cable.
The hall sensors accept voltages between 3.5v and 20v.
The outputs are open collector and require pull-ups to whatever signal level is required.
On the MD49 they are powered from 12v and pulled up to 5v for the signals.
