This gearmotor is a miniature medium-power, 6 V brushed DC motor with a 248.98:1 metal gearbox. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. This version also has a 4.5 × 1 mm extended motor shaft.
Exact gear ratio: 25×34×37×35×38 / 12×10×10×14×10 ≈ 248.98:1
Key specifications:
- voltage: 6V
- no-load performance: 100 RPM, 70 mA
- stall extrapolation: 1.7 kg⋅cm (24 oz⋅in), 0.67 A
Dimensions
- Size: 10 × 12 × 26 mm (Output shafts add 14 mm to the 26 mm length.)
- Weight: 9.5 g
- Shaft diameter: 3 mm (D shaft)
General specifications
- Gear ratio: 248.98:1
- No-load speed @ 6V: 88 rpm (Typical; ±20%)
- No-load current @ 6V: 0.07 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: 0.67 A (This is a theoretical value; stalling the gearbox output shaft will damage the gearbox.)
- Stall torque @ 6V: 2.2 kg·cm
- Max output power @ 6V: 0.48 W
- Extended motor shaft?: Y
- Motor type: 0.67A stall @ 6V (MP 6V)
Performance at maximum efficiency
- Max efficiency @ 6V: 31 %
- Speed at max efficiency: 69 rpm
- Torque at max efficiency: 0.45 kg·cm
- Current at max efficiency: 0.17 A
- Output power at max efficiency: 0.31 W
