Measuring 37 mm (1.46″) in diameter, these 12V and 24V motors are capable of offering huge amounts of torque in a reasonable package. They are available in a range of gear ratios.

With quadrature encoders added to the micro metal gearmotors (with extended back shaft), these motors use a magnetic disc and hall effect sensors to provide 11 counts per revolution of the motor shaft. The sensors operate from 3.3 V to 5 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit.

NOTE: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

Stall Current: 3.1A (24V), 1.6A (12V)
No-Load Current: <0.08A (12V), <0.11A (24V)
At Load Current: <0.50A (12V), <0.65A (24V)

Specifications

Following are specifications for 12V motors -

Variant	Reduction Ratio	Load Speed (RPM)	Max. Efficiency (Torque, Kg-cm)	Stall Torque (Kg-cm)	Gear Box Length
6 RPM	500	5	41	BANNED	29mm
17 RPM	377	14	13.8	50	26.5mm
53 RPM	171	42	4.6	16.8	25mm
100 RPM	103	67	2.9	10.5	23mm
300 RPM	46	202	0.96	3.5	21mm

Following are specifications for 24V motors -

Variant	Reduction Ratio	Load Speed (RPM)	Max. Efficiency (Torque, Kg-cm)	Stall Torque (Kg-cm)	Gear Box Length
12 RPM	506	9	50	BANNED	29 mm
35 RPM	168	28	19	60	26.5 mm
107 RPM	56	85	6.3	25	24 mm
200 RPM	30	137	4	15.5	24 mm
600 RPM	10	410	1.2	5.2	22 mm

What voltages are supported and what encoder specification is included?

The motors are available in 12V and 24V and include a quadrature encoder with 11 counts per revolution. The encoder uses a magnetic disc and hall effect sensors and outputs digital signals that operate from 3.3V to 5V.

How do I connect the encoder to a microcontroller?

The encoder outputs are digital and can be connected directly to a microcontroller or digital circuit since they operate from 3.3V to 5V.

What is the stall current and how should I operate to avoid damage?

Stall current is 3.1A at 24V and 1.6A at 12V. A general guideline is to keep operation at twenty five percent or less of the stall current to avoid rapid thermal damage and reduced motor life.

Are there different gear ratios and how should I choose?

The motors are offered in a range of gear ratios. Please refer to the product specification table for the exact variant values.

What safety and usage guidelines should I follow when using these motors?

Avoid stalling or overloading the motor to prevent damage, ensure sufficient cooling, and select a gear ratio that matches the load and current requirements.
