This gearmotor is a miniature high-power, 12 V brushed DC motor with long-life carbon brushes and a 297.92:1 metal gearbox. It has a cross section of 10 x 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter.

These tiny brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power (MP), and low power (LP) 6 V motors with shorter-life precious metal brushes. The 6 V and 12 V HPCB motors offer the same performance at their respective nominal voltages, just with the 12 V motor drawing half the current of the 6 V motor. The 6 V HPCB and 6 V HP motors are identical except for their brushes, which only affect the lifetime of the motor.

The HPCB versions (shown on the left in the picture) can be differentiated from versions with precious metal brushes (shown on the right) by their copper-colored terminals. Note that the HPCB terminals are 0.5 mm wider than those on the other micro metal gearmotor versions (2 mm vs. 1.5 mm), and they are about 1 mm closer together (6 mm vs. 7 mm).

Exact gear ratio: (25x34x37x35x38) / (12x9x10x13x10) ≈ 297.92:1

General specifications

Gear ratio: 297.92:1
No-load speed @ 12V: 110 rpm, Typical ±20%.
No-load current @ 12V: 0.08 A, Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.
This motor will run at 6 V but is intended for operation at 12 V.
