3X Motion Technologies Co., Ltd. - 常州三协电机股份有限公司

3X Motion Technologies Co., Ltd. is a motor manufacturer headquartered in Changzhou, Jiangsu Province, China, founded in 2002. The company also maintains an office in Nanjing, a manufacturing facility in Bien Hoa City, Dong Nai Province, Vietnam, and a sales office in Houston, Texas, in the United States, giving it a multi-site footprint spanning mainland China, Southeast Asia, and North America. 3X Motion completed a listing on the Beijing Stock Exchange under ticker code 920100 in September 2025.

The company's product range covers several motor technology families: brushless DC (BLDC) motors, BLDC geared motors, hybrid stepper motors (including 28BYA, 33BYA, 42BYA, 42BSA, 42BSB, and 57BSA frame-size series), brushed DC motors, and servo motors, alongside more specialized frameless BLDC motors and servo hub motors. 3X Motion specifically markets a frameless BLDC motor series aimed at the robot industry, offered across an outer-diameter range of roughly 25 to 115 millimeters, in 24V and 48V configurations, with rated torque figures spanning approximately 0.03 to 9.51 newton-meters (and peak torque up to roughly 31.4 newton-meters) and rated power from about 70 to 600 watts; the company promotes this frameless line for its torque density and low cogging torque, characteristics relevant to compact robot joint actuators.

As a vertically diversified motor supplier with decades of manufacturing experience predating the current wave of robotics interest, 3X Motion positions its BLDC, stepper, and frameless motor lines as components usable across industrial automation, robotics, and other motion-control end markets, rather than as a company built exclusively around robotics. Its recent Beijing Stock Exchange listing gives it public-company disclosure obligations that provide an additional layer of verifiable information about its operations, though detailed model-level datasheets beyond the company's own marketing pages were not accessible for this record.

For robotics customers specifically, 3X Motion's frameless motor and servo hub motor lines are designed to be embedded directly into a robot joint housing rather than sold as a self-contained motor unit, which the company markets as an advantage for compact humanoid and collaborative robot joint designs where space and weight are constrained. Combined with its long-standing stepper and BLDC motor catalog, this gives 3X Motion a broad component offering that spans both general industrial motion control and the more specialized needs of robot joint actuation.
