Guang Dong Lihua Mechatronics Co., Ltd. (Lihua Motor), founded in 2003 and headquartered in Humen Town, Dongguan, China, is a National High-Tech Enterprise and an IATF 16949-certified manufacturer with over 22 years of expertise in precision DC motor development and mass production. The company operates 20+ automated production lines with a monthly capacity exceeding 500,000 units, serving more than 1,500 clients across global markets. Lihua Motor's comprehensive product portfolio encompasses brushed DC motors, brushless DC motors, geared motors, and stepper motors — all engineered for demanding applications in automotive systems, medical devices, robotics, industrial automation, and power tools. Backed by 20+ technology patents and internationally recognized certifications including ISO 9001, CE/EMC, RoHS, and REACH, Lihua Motor has built a reputation as a trusted end-to-end custom motor solution provider for OEMs and system integrators worldwide.
Building on this manufacturing heritage, Lihua Motor has officially expanded its flagship RS-775 DC motor series to include a fully customizable 42mm Double Shaft configuration — a strategic move that underscores the company's commitment to delivering high-torque, application-specific drive solutions that meet the evolving demands of modern industrial design.
The new RS-775 Double Shaft DC Motor distinguishes itself with a dual-output shaft design that enables power transmission from both ends of the motor body — a critical advantage in applications such as dual-drive mechanisms, synchronized conveyor systems, and multi-axis robotic joints. Unlike standard single-shaft configurations, the double shaft allows engineers to simultaneously drive two separate loads or attach feedback sensors and encoders on the secondary end without additional gearing or coupling components.
What truly sets this product apart is Lihua Motor's Free-Customization commitment on shaft length. Customers can specify exact shaft dimensions to match their mechanical layouts, eliminating the need for adapters, spacers, or costly redesigns. Combined with customizable voltage (6V | 12V | 24V DC), speed (6,000–15,000 RPM), and torque profiles (up to 250 mNm), each motor can be configured as a drop-in solution for any application.
