This small yet powerful motor is a great solution for small-sized robots.

We have been carrying the SPG10 Micro Metal Gearmotor for quite some time and it has served the makers community well. Many are using it to build the small-sized mobile robot for sumo, small automation model and of course other application too. With this HP (High Power) version, it provides high power with the same miniature size, and this extends the possible application.

This motor comes with 100:1 (100.37:1 to be exact) gearbox attached. The gearbox output shaft is a D-shaped with 9mm long and 3mm in diameter. Besides, this miniature motor also comes with an extended motor shaft (rear of motor), dimension of the rear shaft is 6.0mm (length) x 1 mm (diameter). The extended rear shaft can be used for encoder purpose.  

The rated voltage is 6V, yet we have tried to drive this motor from 3V to 9V. 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.



  • Rated voltage: 6VDC
  • Tested voltage range: 3V to 9V
  • Speed at no load, 6V: 320rpm
  • Current at no load, 6V: 120mA
  • Stall Current, 6V: 1600mA
  • Stall torque, 6V: 211.8mN.m (2.16kgfcm)
  • Weight: 9.5g
  • Gear ratio: 100:1 (100.37: 1 to be exact)
  • Shaft: D-shaped with 3mm diameter, 9mm in length

Packing List:

  • 1 x 6V 320RPM High Power DC Micro Metal Gearmotor

Hi, this motor speed 320RPM is after the gearbox or before? ( Bazli, 09/02/2019 )
Hi, it is the speed after the gearbox :)
Hi..May I know when this item will restock ? ( Hasrul, 17/08/2018 )
Hi, we already have stock https://www.cytron.io/p-spg10hp-100k
if the stall torque is 2.16kg/cm, how about the instant torque? ( syukran, 19/07/2018 )
Hi, sorry the instant torque value is not provided by the supplier.
can i use battery 9v for this motor ? ( nurul natasyha, 18/11/2017 )
Hi, we already tested this motor with voltage range: 3V to 9V. Thanks.
Hello, May I know the correct length of this gear motor? Because it mentions length is 42mm however in datasheet show the length is 32mm. Which one is correct? ( AIZAT, 03/06/2017 )
Hi, it is state under product description, the motor dimension is 10 x 12 x 41.2mm. So the length is 41.2mm. For more detail you can refer to SPG10-HP Dimension. For further questions, you can go to our technical forum, as this session only for short inquiry. Thanks.
May i know what is the maximum load this motor can carry ?
( Fairuz, 02/06/2017 )
Hi, you can check on the Stall Torque parameter under Description tab. Thanks.
