Small Gear Motors (Small DC Gear Motors) for OEM & Custom Designs
Small Gear Motors are compact DC motors combined with a gearbox to deliver the right torque at the right speed in limited space.
At INEED Motors, “small gear motors” refer to our micro & small DC gearmotor solutions with motor diameters 6mm to 42mm, including spur gear motors, planetary gear motors, worm gear motors, and brushless gear motors.
If you’re not sure which gearbox fits your application, start with our Product Guide (filter by diameter / voltage / RPM / torque), or send your requirements for an engineer recommendation.

We provide you with the perfect miniature electric motor solutions. Whether it’s utilizing brushless DC motors or brushed DC motors with in-core or coreless motor designs or adding encoders for position sensing or feedback, we are able to meet your specific requirements. There are 3 popular types of gearheads on the market: spur gearheads, planetary gearheads, and worm gearheads combined with our micro DC gear motors. They are compact, cost-effective, and suitable for OEM applications. Offering endless possibilities for your application, all our mini gear motors are carefully crafted to work seamlessly with your imagination and design.
Spur Gear Motor
Compared with other mini DC gear motors, spur gear motors have high transmission efficiency to meet your application. They are simple, easy to make, and easy to install. Spur gear motors are ideal for low torque and duty cycle requirements applications. The N20 gear motor is a highly typical member of our spur gear motor lineup and finds wide application across various industries. It has gained additional recognition as a key component in shared bicycle smart locks.
Planetary Gear Motor
A planetary Gear Motor is a small high torque electric motor that provides low-speed and high torque at the same time. They can handle varying loads with minimal backlash and are best suited for intermittent operation, offering infinite reduction ratios to meet all speed and torque requirements for OEM applications. Our 6mm diameter metal planetary gear motors are perfectly suited for applications where space is limited, but high torque is required.
Worm Gear Motor
Small worm gear motors are the most load-bearing capacity micro gear motor type due to their special worm gear material and large gear contact area. They also feature self-locking functionality and a rectangular output shaft. Changing the polarity and rotational direction is easily achieved. Available in various gear ratios, voltages, and sizes, INEED Motors provides multiple types of small geared electric motors with worm gearheads for your application needs.

FAQ for Small Gear Motors
What is a small gear motor?
A small gear motor is a compact DC motor equipped with a gearbox to reduce speed and increase torque, enabling stable motion in space-limited OEM devices.
How do I choose a small DC gear motor?
Define your voltage, target RPM (under load), required torque, size limit, and duty cycle. Then use our Product Guide to shortlist models, or send us your requirements for a recommendation.
Spur vs planetary vs worm — what’s the difference?
Spur is efficient and cost-effective, planetary provides higher torque density in a compact body, and worm is strong under load and can be self-locking for holding applications.
What information is needed for customization?
Voltage, target speed, target torque, diameter/length limit, shaft type, duty cycle, and application details. If available, share drawings or prototypes.
Plastic gears vs metal gears — which should I choose?
Plastic gears are quieter and lightweight for light loads; metal gears provide higher torque capacity and better wear resistance for heavier duty or longer life requirements.
Can I control RPM using PWM?
Yes. PWM is widely used for DC gear motors. Always evaluate torque under load and thermal performance at your duty cycle.
What’s the Lead time for samples and orders?
Samples are typically 7–10 days. Mass production lead time depends on quantity and customization requirements.
