Our 12mm N20 spur gear motor is a compact, production-ready drive solution developed for smart locks and other space-limited mechanisms that require reliable torque and repeatable motion. It supports common operating voltages of 2.5V, 5V, 9V, and 12V, making it easy to integrate with battery packs, control boards, and standard motor drivers without complex redesign.
From an engineering perspective, this N20 gear motor can be configured to match your load profile: we can customize gear ratio, output speed, and torque, and support practical integration requests such as adding connectors or lead wires, shaft adaptations (e.g., adding a gear), and optional encoder integration for feedback control. This flexibility helps shorten design cycles and reduces assembly risk when moving from prototype to mass production.
From a purchasing and supply perspective, the product is field-verified by multiple smart-lock customers and has demonstrated stable performance in real applications. Our annual shipment volume reaches 1,000,000 units, with zero customer complaints, zero returns, and no reported quality issues—an important benchmark for OEM buyers who prioritize consistency, traceability, and long-term supply.
Share your target RPM, required torque, available installation space, and wiring/connector preferences, and we will recommend an optimized configuration and provide a fast quotation.
Customizable items: 1. Length and shape (A ); 2. Voltage, output speed, torque, etc. ; 3. Adding connectors, lead wires; 4. Adding gears to shaft; 5. Adding encoder.

A. Yes. This 12mm N20 gear motor is widely used in smart lock designs and has been validated by multiple smart-lock customers in real applications. It is designed for stable, repeatable output and can be configured for the speed/torque needed by lock actuators and small transmission structures.
A. Common options include 2.5V, 5V, 9V, and 12V. Choose the voltage based on your power source (battery or adapter), available driver current, and your target speed/torque under load. If you share your power supply details and performance targets, we can recommend the best winding and configuration.
A. We support customization of gear ratio, output speed, and torque, plus integration options such as connectors or lead wires, adding a gear to the shaft, and optional encoder integration for feedback control. This helps match the motor to your mechanism and simplifies assembly for mass production.
