Description

This gearmotor is a powerful brushed DC motor with 6.25:1 metal gearbox intended for operation at 12 V. 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 with an integrated encoder(PO4757).

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 × 50L mm(Length measurement is from gearbox face plate to back of motor (it does not include the output shaft or motor terminals). )
Weight:175 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
