EMG30, mounting bracket and wheel specification
The EMG30 (encoder, motor, gearbox 30:1) is a 12v motor fully equipped with encoders and a 30:1 reduction gearbox. It is ideal for small or medium robotic applications, providing cost effective drive and feedback for the user. It also includes a standard noise suppression capacitor across the motor windings.
Measurements
Connector
The EMG30 is supplied with a 6 way JST connector (part no PHR-6) at the end of approx 90mm 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 | |
| Red (5) | + Motor | |
| Black (6) | - Motor |
Wire colours are 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 MD25 they are powered from 12v and pulled up to 5v for the signals.
