SPG20-50K is a small-size geared motor coupled with a 50:1 gearbox. It is a general purpose DC geared motor for some simple automation projects.

The rated voltage is 12V, 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.

For Arduino lover, get the 2A Motor Driver shield to control this motor with Arduino.

  • Rated Voltage:12VDC
  • No load current: < 40mA
  • No load speed: 125 ± 12 RPM
  • Rated load torque : 49mN.m (0.5kgf.cm)
  • Rated current: < 150mA
  • Rated load speed: 90 ± 9 RPM
  • Weight: ~ 60g
  • Shaft: D-shaped with diameter 4mm x length 11mm
  • Motor dimension : 50mm x 27.2mm x 27.2mm, detailed drawing
  • Gear ratio: 50:1
  • Sample application: Lightweight mechanism
For Arduino lover, you may need 2Amp Motor Driver Shield :)

Hi, can 2 of this motor support weight around 3kg ( REDZA , 15/05/2020 )
Hi, not really. You may refer to this link. Thanks :)
Does the motor come with wire ? What is the connector? What is the motor shaft diameter and shape? ( Jackson Ng, 13/05/2020 )
Hi, yes it comes with a wire.
Shaft: D-shaped with diameter 4mm x length 11mm
Thanks :)
May I know what is the Stall Torque of this motor (aka torque value that slows the motor down and causes it to stop)? ( Ryan, 20/11/2019 )
Hi, we're sorry as we do not have the data for the time being. Thanks :)
i need a mini motor to rotate a brush which use to clean something. but i need different low speed like 60rpm to 200rpm. so can it change the speed by changing the input current? ( LK , 01/08/2019 )
Hi, you can control it using PWM (control voltage)
Plastic Wheel for SPG30/SPG50 (80mm) can these fit?

( Bravinraam Naidu, 13/01/2019 )
Hi, it is not suitable.
What is the RPM'S of this motor and will it operate with 12 volts? ( Rockey, 31/10/2017 )
Hi, the no-load speed (r.p.m) is 125 ± 12 and rated voltage is 12 volts. Thanks
Hello is there any of your shop near kuala lumpur and can i have the address ( Imran, 28/09/2016 )

Hi, Sorry we do not have store. You can buy through our website

can this motor support on a conveyor ? ( asheanuar, 17/08/2016 )


If you just make it as model conveyor then you can use it. But if you want to use it properly then we recommend you to use DC Geared Motor SPG30. 

For further inquiry, kindly visit our technical forum as this session is only for short inquiry. Thanks.smiley

can this gear motor support load more than 40kg ? ( naufal, 20/03/2016 )

Hi. The suitability is depending on your mechanism, torque of the motor and other factors. Kindly continue the discussion in our technical forum as this session is only for short inquiry. Thanks. :)

Never tried it at under 16 dC and manufacturer does not test the operating temperature, sorry.
