A DC torque motor is a special type of brushless permanent magnet synchronous motor. Since the load is directly connected to the rotor, no transmission components are required, making the torque motor a direct drive technology. The torque motor is also known as a "frameless" motor. This means the motor lacks a housing, bearings, or measurement system. These components are selected by the machine manufacturer based on the required performance, or purchased as a complete set.





The torque motor employs a permanent magnet brushless motor design, consisting of a ring-shaped stator and a ring-shaped rotor. The stator does not use a toothed lamination design but is composed of smooth cylindrical laminations. The rotor is made up of multi-pole rare earth permanent magnet poles and a ring-shaped hollow shaft. This structure features a large air gap and uniform magnetic resistance throughout the entire working air gap, thus providing the advantage of zero-slot torque.






Yunxi Electromechanical Technology Co., Ltd. in Langfang is a company that collaborates with universities to produce permanent magnet synchronous DC torque motors. With the establishment of the current mechatronic automation equipment system, brushless DC torque motors have become fundamental components for automatic control. After years of technical accumulation, our products are now applied in collaborative robots, underwater robots, CNC machine tools, optoelectronic systems, satellites, radar, shipborne equipment, and more.
