30:1 Metal Gearmotor 37Dx52L mm 12V (Helical Pinion)

This gearmotor is a powerful brushed DC motor with 30:1 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.Key specifications: voltage no-load performance stall extrapolation 12 V 330 RPM, 200 mA 14 kg⋅cm (190 oz⋅in), 5.5 AMeasuring 37 mm (1.46″) in diameter, these brushed DC gearmotors are the largest and most powerful we carry. They are available in a range of gear ratios from 6.3:1 to 150:1 and with 12 V or 24 V motors, and all versions are available with integrated 64 CPR quadrature encoders on the motor shafts. The 12 V and 24 V motors offer approximately the same performance at their respective nominal voltages, with the 24 V motor drawing half the current of the 12 V motor. See the 37D metal gearmotor datasheet (2MB pdf) for more information, including detailed performance graphs for each gearmotor version.Key specifications:Voltage no-load performance stall extrapolation 12 V 330 RPM, 200 mA 14 kg⋅cm (190 oz⋅in), 5.5A
