Description
Reviews

This gearmotor is a powerful 12V brushed DC motor with a 6.25:1 metal gearbox and an integrated quadrature encoder that provides a resolution of 64 counts per revolution of the motor shaft, which corresponds to 400 counts per revolution of the gearbox’s output shaft. The gearbox is composed mainly of spur gears, but it features helical gears for the first stage for reduced noise and improved efficiency. These units have a 16 mm-long, 6 mm-diameter D-shaped output shaft. This gearmotor is also available without an encoder(PO4747).

Exact gear ratio: 25×30 / 10×12 = 6.25:1

Key specifications:

voltage: 12 V
no-load performance: 1600 RPM, 200 mA
stall extrapolation: 3.0 kg·cm (42 oz·in), 5.5 A

Dimensions

Size: 37D × 65L mm (Length measurement is from gearbox face plate to back of encoder cap (it does not include the output shaft). )
Weight: 190 g
Shaft diameter: 6 mm (D shaft)

General specifications

Gear ratio: 6.25:1
No-load speed @ 12V: 1600 rpm
No-load current @ 12V: 0.2 A
Stall current @ 12V: 5.5 A
Stall torque @ 12V: 3.0 kg·cm (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.)
Max output power @ 12V: 12 W
No-load speed @ 6V: 800 rpm
No-load current @ 6V: 0.15 A
Stall current @ 6V: 3.0 A
Stall torque @ 6V: 1.7 kg·cm(This motor will run at 6 V but is intended for operation at 12 V.)
Motor type: 12V

Performance at maximum efficiency

Max efficiency @ 12V: 47 %
Speed at max efficiency: 1300 rpm
Torque at max efficiency: 0.49 kg·cm
Current at max efficiency: 1.2 A
Output power at max efficiency: 6.4 W
