"Your One-Stop Partner in Motion Control Components & Solutions"
Shenzhen manufacturer of frameless torque motors, magnetic/inductive encoders and integrated robot joint modules for robotics and motion control.
Shenzhen Mosrac Motor Co., Ltd. is a Chinese manufacturer founded in 2010 that designs and produces motion-control components for robotics and precision automation. The company is based in Bao'an District, Shenzhen, in the COFCO (Fu'an) Robot Technology Park, operating a plant of roughly 7,000 square meters. Mosrac's product range centers on direct-drive frameless torque motors, available in inrunner and outrunner configurations as well as variants for linear joints, with stator outer diameters spanning approximately 16 mm to 200 mm to cover a wide span of torque, speed and current requirements. Alongside motors, Mosrac manufactures high-precision feedback devices including inductive encoders and magnetic encoders, which are commonly paired with its motors in closed-loop joint designs. A key product line is the company's integrated servo robot joint module, combining motor, reducer, encoder and drive electronics into a single actuator; these include harmonic and planetary joint modules used in collaborative robot arms, medical devices, industrial modules and smart-manufacturing equipment.
The company also supplies DD (direct-drive) motors and RV reducers. Mosrac's components serve applications across industrial robotics, automation, medical and in-vitro diagnostic equipment, semiconductor manufacturing, printing, packaging and laboratory automation, where precise, repeatable motion is required. The company operates an ISO 9001 quality management system and offers both standard catalog products and custom-engineered solutions sourced from a single supplier, supporting customers building robot joints and motion-control axes.
Primary type & automation activities this supplier delivers:
Frameless direct-drive inrunner torque motors for compact, high-torque robot joints and rotary axes.
Integrated servo joint combining frameless motor, harmonic reducer, encoder and drive for cobot arms.
High-precision magnetic rotary encoders for closed-loop motor and joint feedback.
