6mm Coreless Metal Gearbox Motor Model NFP-612-266-MG-M3

Metal Gearbox 6mm Micro Motor With Brass Threaded Screw Parameter

First, the NFP-612-266-MG-M3 is a compact 6mm full metal gear reducer motor with an M3 brass threaded screw. Also, it is designed for small drive systems that need low noise, smooth output, and stable linear movement.

In addition, this motor uses a brushed motor structure and is suitable for intermittent work. Therefore, it is useful for compact products that need short-time motion and controlled positioning.

Moreover, the all-metal planetary reduction gearbox helps provide strong torque in a very small size. As a result, the motor can support micro actuators, small robots, medical devices, and precision mechanisms.

Main Product Features

• First, full metal gearbox: The 6mm planetary gearbox supports high strength and stable output.
• In addition, low noise: The listed noise value helps support quiet compact products.
• Also, smooth operation: The extended shaft head is stable and helps reduce shaking.
• Next, brushed motor design: The motor is suitable for intermittent work and simple control.
• Moreover, M3 brass threaded screw: The screw can work with an M3 nut for linear movement.
• Finally, custom screw length: The brass threaded screw can be cut by the user if needed.

Brass Threaded Screw Details

First, the M3 brass threaded screw has a total length of 105mm. Also, it can be equipped with an M3 nut for small linear drive systems.

In addition, one end has a 2mm diameter D-type hole with 3mm hole depth. Therefore, it can match the D-type output shaft of the 6mm reduction motor.

Moreover, the D surface height is 1.5mm, and the screw also has an M1 screw hole for fixing. As a result, users can install the threaded screw more securely.

Gearbox Structure Notes

First, the all-metal planetary reduction gearbox helps improve strength in a small size. Also, the motor shaft head D-cut surface is 3mm.

In addition, the gearbox and gear use a powder metallurgy process. Therefore, the gear system can support compact torque transmission under suitable load conditions.

Basic Motor Specifications

First, the table below shows the main motor data. Also, it helps users check voltage, ratio, stage, speed, wire length, weight, noise, torque, and environment limits before testing.

Therefore, this model is a good option for compact drive systems that need a 3.7V DC motor, 266:1 ratio, and M3 threaded screw output. In addition, the 3.3g weight helps reduce the total product size and mass.

• In addition, M3 threaded screw: The screw supports compact linear movement with an M3 nut.
• Also, D-type hole: The 2mm D-type hole helps match the 6mm gear motor output shaft.
• Next, M1 fixing hole: The fixing hole helps secure the threaded screw during use.
• Moreover, custom length: Users can cut the brass threaded screw to the needed length.
• Finally, clear drawings: The drawings help reduce design errors before production.

Applications and Selection Tips

Typical Applications

Finally, this 6mm micro gear motor with brass threaded screw is useful for compact products that need small size, low speed, and linear motion. For example, it can work in micro actuators, robotic hands, medical devices, model mechanisms, and precision tools.

• First, micro actuators: The M3 threaded screw helps create small linear movement.
• In addition, robotic hands: The compact gearbox can support finger and joint motion.
• Also, medical devices: The low-noise design helps small care and test equipment.
• Next, model mechanisms: The motor can drive small push, pull, and lift parts.
• Moreover, precision tools: The 266:1 ratio helps provide controlled low-speed output.
• Finally, custom devices: The cuttable brass screw helps fit different stroke designs.

How to Choose This Motor

First, check whether the product can use a 3.7V DC motor. Also, confirm that the voltage range of 3V−4.2V matches the battery or control board.

In addition, check the required output speed and torque. Therefore, users should compare the 101RPM no-load speed and ≥ 250 gf.cm stall torque with the real load.

Moreover, confirm the M3 threaded screw length, nut fit, stroke range, and installation space. As a result, users can reduce mechanical changes before sample testing.

Final Selection Notes

• First, check voltage: Use 3V−4.2V power and 3.7V DC rated voltage.
• In addition, check ratio: Use the 266:1 ratio for low-speed output.
• Also, check screw length: Confirm the 105mm M3 brass threaded screw length before design.
• Next, check nut fit: Use a suitable M3 nut for linear motion.
• Moreover, check shaft fit: Confirm the 2mm D-type hole and 3mm hole depth.
• Also, check duty cycle: Use the brushed motor for intermittent work.
• Finally, test real load: Confirm speed, current, noise, torque, stroke, and temperature before production.

In short, the NFP-612-266-MG-M3 is a compact 6mm planetary DC gear motor with M3 brass threaded screw for products that need 3.7V DC power, low noise, 266:1 reduction, small size, and custom linear motion.
