Our Advantages As Your DC Gear Motors Supplier

The Most Popular N20 Gear Motor
N20 gear motor is a specific type of miniature electric motor that is combined with a gearbox to achieve specific mechanical characteristics. The “N20” refers to the size of the motor, and N20 gear motors are known for their small form factor and versatility. N20 gear motors are used in a wide range of applications, including toys, small robots, camera mechanisms (for focus and zoom), door locks, and various consumer electronic devices.
SLW MOTOR has a variety of gearboxes that can be configured with N20 motors. These gearboxes include 90-degree worm type, conventional extended shaft type, parallel shaft type, and also include plastic planetary gearboxes. Encoders are also widely used in N20 motors.

High Quality Planetary Gear Motor
A DC planetary gear motor is a type of gear motor that combines a direct current (DC) electric motor with a planetary gearbox,Depending on the application requirements, planetary gearboxes can be with a brushed DC motors or a brushless DC motors to meet higher market demand.
Designing and manufacturing planetary gearboxes involves advanced engineering and precision manufacturing processes,Designing and producing planetary gearboxes requires more professional technology and experience, and the smaller the outer diameter of the planetary gearbox, the higher the difficulty. SLW Motor uses mature and stable technology to mass-produce planetary gearboxes and planetary gear motor with an OD of 10mm or more. Gearbox motors, a design and production capability that even exceeds that of many larger and longer-standing motor manufacturers.

Cost-Effective and excellent service
Plastic planetary gear motors incorporate plastic components, such as gears and housing, offering advantages like reduced weight, cost-effectiveness, and corrosion resistance. They are ideal for applications where weight and cost are crucial, such as in aerospace, drones, and portable devices. While plastic gears are less durable than metal, they provide significant benefits in specific scenarios.
Additionally, plastic planetary gear motors offer noise reduction, as plastic gears are quieter than metal ones. However, their load-carrying capacity and lifespan are limited compared to metal gears, making them best suited for applications where these limitations are acceptable.

Powder Metallurgy Gear Motor
A powder metallurgy (PM) gear motor uses gears or gear parts manufactured through the powder metallurgy process, which shapes and sinters metal powders to create precise components. This cost-effective technique allows for the production of intricate and complex gear shapes that would be difficult or expensive to achieve with traditional machining methods, making it ideal for custom gear profiles.
Powder metallurgy can be applied with various metal powders, such as iron, steel, stainless steel, and bronze, depending on the desired properties and application requirements. This flexibility offers significant advantages in terms of both design and material selection for gear motors.
