These cylindrical brushed DC gearmotors are available in a wide range of gear ratios, from 25:1 up to 488:1, and with three different motors: 6 V and 12 V motors with long-life carbon brushes (CB), and a 6 V motor with shorter-life precious metal brushes. All three motors offer similar performances at their respective nominal voltages, just with the 12 V motor drawing approximately half the current of the 6 V motor and with the carbon brush versions having longer lifetimes than the one with precious metal brushes.

The CB versions (shown on the right in the picture below), can be differentiated from versions with percious metal brushes (shown on the left) by their copper-colored terminals.

These gearmotors are optionally available with an additional 2 mm-diameter output shaft that protrudes 6 mm from the rear of the motor (see the middle picture below). This rear shaft rotates at the same speed as the input to the gearbox and offers a way to add an encoder, such as our magnetic encoder for 20D mm metal gearmotors as shown in the right picture below, to provide motor speed or position feedback.The gearmotors all have 20 mm diameter gearboxes and 4 mm diameter gearbox output shafts, so it is generally easy to swap one version for another if your design requirements change (though the length of the gearbox tends to increase with the gear ratio).

Dimensions

General specifications

Gear ratio: 62.5:1
No-load speed @ 6V: 230 rpm
No-load current @ 6V: 0.15 A
Stall current @ 6V: 2.9 A3
Stall torque @ 6V: 4.0 kg·cm3

Performance at maximum efficiency

Max efficiency @ 6V: 37 %
Speed at max efficiency: 190 rpm
Torque at max efficiency: 0.71 kg·cm
Current at max efficiency: 0.61 A
Output power at max efficiency: 1.4 W

Notes:

  • Not including output shafts; output shafts add 24 mm to the total length.
  • D shaft.
  • Stalling is likely to damage the gearmotor. Stall parameters come from a theoretical extrapolation of performance at loads far from stall. As the motor heats up, as happens as it approaches an actual stall, the stall torque and current decrease.
