EMG49 gear-motor with encoder

Devantech

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

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