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
Measurements
Connectors
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.
