High-torque micro drives, BLDC speed-controlled systems, and customized miniature gearmotors designed for global OEM/ODM applications.
Chengdu KPM Minimoto Co., Ltd. is a professional mini DC motor manufacturer specializing in micro motors, gear motors, and precision drive solutions for a wide range of industrial and commercial applications. As an OEM and ODM manufacturing partner, the company provides customized motor solutions for equipment manufacturers, automation integrators, and technology companies around the world.
Founded in 2011 and headquartered in Chengdu, Sichuan Province, China, KPM Minimoto operates a modern production facility covering more than 7,500 square meters with a workforce of over 150 employees. The company integrates research and development, precision engineering, manufacturing, quality assurance, and global sales to deliver reliable motion control solutions tailored to customer requirements.
KPM Minimoto's product range includes mini DC motors, micro gear motors, planetary gear motors, brushless DC (BLDC) motors, coreless motors, encoder motors, and customized drive assemblies. These products are widely used in robotics, smart devices, medical equipment, office automation systems, household appliances, security equipment, vending machines, industrial automation, and precision instruments.
Modern electromechanical systems demand unprecedented energy density, thermal tolerance, and position control. KPM Minimoto bridges advanced Western engineering standards with China's rapid prototyping and scalable manufacturing infrastructure. By maintaining an in-house precision gear-hobbing workshop and automated stator winding lines, we guarantee mechanical backlash below 15 arcminutes and operational acoustic profiles under 35dB for medical and luxury automation clients.
The global transition toward electro-mobility, surgical robotics, and intelligent industrial automation is driving radical architectural changes in micro drive manufacturing. As a pioneering China electric drive motors factory, Chengdu KPM Minimoto is actively advancing next-generation motion technologies across four fundamental pillars:
Eliminating cogging torque and iron core losses through self-supporting basket windings. Ideal for high-speed surgical instruments and micro-drones requiring zero torque ripple and extreme dynamic acceleration.
Embedding GaN (Gallium Nitride) power FETs and magnetic/optical absolute encoders directly into the motor end-bell. This compact mechatronic approach minimizes EMI, reduces cabling complexity, and enables real-time CANopen/EtherCAT communication.
Utilizing high-precision sintered alloy gears and planetary reduction systems designed to endure peak startup loads exceeding 50 Nm while maintaining compact radial envelopes below 42mm.
