Product Description
This gearmotor is a miniature low-power, 6 V brushed DC motor with a 986.41:1 metal gearbox, making it a great choice for applications requiring fine control at very low speeds. 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. (Note: stall torque and current specifications are theoretical values; stalling the motor will damage the gearbox.)
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.
Exact gear ratio: 25×34×35×34×34×34×27 / 12×9×12×14×14×14×9 ≈ 986.41:1
General specifications
- Gear ratio: 986.41:1
- No-load speed @ 6V: 13 rpm, Typical ±20%
- No-load current @ 6V: 0.04 A, Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.
- Stall current @ 6V: 0.36 A. This is a theoretical value; stalling the gearbox output shaft will damage the gearbox.
- Stall torque @ 6V: 5.5 kg·cm
- Extended motor shaft?: N
- Motor type: 1.6A stall @ 6V (HP 6V)
- Size: 10 x 12 x 29.5 mm, Output shaft adds 9 mm to the 29.5 mm length.
- Weight: 10.5 g
- Shaft diameter: 3 mm D shaft.
Performance at maximum efficiency
- Max efficiency @ 6V: 24 %
- Speed at max efficiency: 10 rpm
- Torque at max efficiency: 1.2 kg·cm
- Current at max efficiency: 0.09 A
- Output power at max efficiency: 0.12 W
