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 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
cable as standard.
The connections are:
|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.
|Rated torque||16 kg/cm|
|No load speed||143|
|No load current||500mA|
|Encoder counts per output shaft turn||980|
EMG49 Mounting Bracket
Providing easy mounting of the EMG49 to the robot, the bracket is made from a 2mm thick strong aluminum and finished in blue enamel.
A 125mm diameter wheel with 8mm diameter hub for easy attachment to the EMG49, the wheel has a 28mm wide rubber tread
