A DC torque motor is a special type of brushless permanent magnet synchronous motor, as 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, meaning it has no housing, bearings, or measuring system. These components are selected by the machine manufacturer based on the required performance or purchased as a complete set.





The torque motor utilizes a permanent magnet reluctance brushless motor design. The motor is composed of a ring-shaped stator and a ring-shaped rotor. The stator does not employ a toothed lamination design, but is instead made up of smooth cylindrical laminations. The rotor consists of multi-pole rare earth permanent magnet poles and a ring-shaped hollow shaft. This structure is characterized by a large air gap, ensuring a uniform magnetic resistance throughout the entire working air gap, thus endowing the motor with the advantage of zero-slot torque.






Yunxi Electrical and Mechanical 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 mechatronics automation equipment system, brushless DC torque motors have become fundamental components for automatic control. After years of technological accumulation, our products are now applied in areas such as collaborative robots, underwater robots, CNC machine tools, optical-electronic systems, satellites, radars, and shipborne equipment.
