The famous SPG30 gear motor is mounted with a quadrature hall effect encoder allowing us to do monitoring in position and direction of the motor rotation. This is very useful especially when we are building a pulling system or conveyor system. Two hall effect sensors are placed 90 degrees apart to sense and produce two outputs, A and B which is 90 degrees out of phase and allowing the direction of rotation to be determined.
Please watch the video below to see how cool is it to have encoder feedback for your DC motor.
This motor is mounted with a 60:1 gearhead that able to produce 294mN.m torque with 75RPM. The maximum current of this motor may exceed 1 amp, so please make sure you drive it with a DC motor driver that can withstand at least 2 amp current.
For mounting, the depth of the thread of the motor is 3.2 mm. So, you need to use an M3 screw that shorter than 3.2 mm. A longer screw will damage the gearbox. You may need to consider the thickness of the bracket or other external parts that you need to mount with the motor before choosing the screw.
