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.
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:
|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.
|No load speed||216|
|No load current||150mA|
|Encoder counts per output shaft turn||360|
|Measured Shaft Speed when used off-load with MD23 and 12v supply.|
EMG30 Mounting Bracket
Providing easy mounting of the EMG30 to the robot, the bracket is made from a 2mm thick strong aluminum and finished in blue enamel.
A 100mm diameter wheel with 5mm diameter hub for easy attachment to the EMG30, the wheel has a 26mm wide rubber tread
