EMG30 gear-motor with encoder

Devantech

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 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

note that pull up resistors (we used 4k7) are required on the hall sensor outputs, and wires are the colours from the actual cable.
