6mm DC Gear Motor – Smallest Gear Motor Used For Lock

6mm Nano Planetary DC Gearmotors

---

In early times, this kind of micro-planetary gear motor is sold on site Gizmoszone.com(model GH612M, GH6121S, GH6122S, GH6123S, GH6124S…). This small DC electric geared motors can be used for driving robot. All the motors in this page are just 6 millimeters in diameter, narrower than a pencil. The gearhead and the shaft are made from glass-fiber reinforced engineering plastic. Unlike the general cylindrical pager motors these motors have gearbox (inside 1-4 stages gears). The gear-head mechanically change the speed for increasing in push strength. If use the ordinary 6mm coreless motor in stead of the gearhead motor, that wouldn’t have that torque to drive.

This 6mm planetary gear motor is a combination of different motors and a gearboxes, of which there are four gearbox options, they are 1 gear reduction ratio, 2 gear reduction ratio, 3 gear reduction ratio, 4 gear reduction ratio. The choice of motor is 6mm diameter: 9mm length, 12mm length, 14mm length, 15mm length, 4 kinds of choices, there are 16 kinds of optional small dc gear motors in this combination.NFP-motor is the source manufacturer of small gear motor. The efficiency and performance have reached the best results. There are 16 kinds of torques options, the parameter tables are below, and 6mm planetary gear motor model 609 series is in stock now. Samples can be shipped directly. The diameter of all miniature gear motors this page is Φ6mm, only difference is the length of the micro gear motors .

For this micro gear motor is light and compact, it can be used in a wide range of applications, including drives for industrial or consumer products, as well as medical products and beauty products such as electric eyelash brushes. According to different product requirements, small gearmotors with different speeds, different ratios and different torques can be selected.

Inside the gearbox, there are 1-4 stages of gears, and each stage has two or more plastic gears to produce four reduction ratios, torques, speeds. The 6mm gear motors can be made as custom, with a JST/Molex connector, wire length options.

Note: Do’s And Don’ts

---

1. Don’t use the 6mm planetary gear motor beyond the maximum torque as described.
2. Don’t exceed the shaft loading higher than 0.5N (5mm from the mounting face). This will caused damage of shaft or teeth stripped.
3. Do use at operating voltage 3V DC only.
4. Do take care to avoid shocks or bend of precise geared. Damage or deformation may result in Gearmotors out of order.
