Cytron DC Geared Motor SPG30-20K
Cytron DC Geared Motor SPG30-20K
SPG30 is 1.1W DC brushed motor with compact size, a low-cost solution for projects such as a medium-size robot, omni drive robot, mechanism, etc.
We have been carrying SPG30 motor for quite some time and it has served the makers community well. It is being used in student final year project, and competition robot. This model of SPG30 brushed motor comes with 20:1 gearbox attached. The gearbox output shaft is a D-shaped with 15.5mm long and 6mm in diameter.
All SPG30 motors are DC brushed motor with gearbox. The rated voltage is 12V (except stated), yet we have tried to drive this motor from 9V to 15V. Lower voltage might not have enough torque to drive the wheel or mechanism; higher voltage will provide higher torque and higher speed, but it will shorten the life of the motor.
Mounting
For mounting, the depth of the thread of the motor is 3.2 mm. So, you need to use 3.2 mm length of M3 size screw (not included with the thickness of the bracket). Longer screw will damage the gearbox. You may need to consider the thickness of the bracket or other mechanisms that you need to attach to the motor for choosing the right length of screw.
