What Can Our Gear Motors be Customized?
We can combine any gearbox design with any type of motor technology. We commonly use three motor configurations:
Brushed iron core motor: The lowest cost option, durability can be improved through reasonable component design. Typically used in motors with frame diameters greater than 8 mm.
Brushless iron core motor: Needs special drive circuit and three-phase controller, highly wear-resistant. Offers superior torque density in compact sizes, mainly used in motors exceeding 12mm frame diameter.
Brushless coreless motor: Coreless design ensures ultra-low rotor inertia, smooth operation, and zero cogging. Delivers fast response and high efficiency, ideal for precision, small motors demanding rapid responsiveness in advanced applications.

Shaft Length
- Short Shaft: Compact designs for limited installation space or direct coupling.
- Extended Shaft: Provides flexibility for mounting pulleys, gears, couplers, or encoders.
- Plain Round Shaft: Smooth cylindrical shaft, sometimes with a flat cut (D-shaft) for slip-free coupling.
- D-Cut Shaft (D-Flat): One side flattened to ensure secure fit with gears, pulleys, or set-screws.
- Keyed Shaft: Slot (keyway) cut along the shaft for use with a matching key in couplers or gears to prevent slipping.
- Internal Threaded Shaft (Tapped Hole): Allows fastening components directly with a screw or bolt into the shaft.
- External Threaded Shaft: Shaft end machined with threads for nut-fastened connections.
- Cross-Drilled Shaft: Hole drilled through shaft for pin connections, commonly seen in robotics or light couplings.
Metal Gearbox: High strength handles heavy loads and torque without deformation, offering long life, wear resistance, and reliable performance in high-temperature demanding environments.
Plastic Gearbox: For geared motors with a diameter less than 10 mm, metal gears are very expensive, so we use gears made of MIM injection-molded engineering plastics.
