Established in 1992, China Qiangjin Power Co., Ltd. is a professional torque motor manufacturer and dealer of in the emergency power supply industry. We not only specialize in manufacturing different kinds of generators, but also in motors, engines, diesels, gearmotors and other power supply products. Now, our OEM torque motors products are exported to North America, Europe(UK, France, Germany, Italy), USA, Japan and Canda. Our company has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS.

Moog Components Group brushless torque motors are designed to operate over a range of speeds for a wide variety of military, aerospace and industrial applications. Different applications require unique configurations of mounting flanges, housings, output shafts and electrical requirements. Our motors have high torque-to-power and torque-to-inertia ratios, high linearity and low electrical time constants. Reliability and long life are hallmarks of our products and since these are brushless motors, there are no carbon brushes to wear out.
Moog Components Group offers a full range of products and a unique level of product support, including engineering development and aftermarket support. Whether torque motor or servomotor, framed or housed, our applications engineers will assist you with your critical application requirements.

Torque motors are available in a wide range of sizes, with diameters from smaller than 100 mm to larger than 1 m. Motor diameter is similar to frame size for conventional brush-less servomotors. And for a given diameter, several axial lengths are available.
Torque motors have a large number of magnetic pole-pairs with many permanent magnets on the rotor. Torque motors can be built as thin rings. They have smooth velocity modulation with low ripple. Eddy-current losses in torque motors constrains the maximum practical number of pole pairs and speed. As a result, torque motors are primarily designed for low/mid-speed range applications, generally below 1,000 rpm.
Torque motors produce high torque at stall and can have high dynamic stiffness. However, the motor alone does not determine dynamic stiffness or precision. To exploit the full benefits of direct-drive, an integrated rotary table must also contain precision feedback device and high stiffness bearing to provide a high-performance rotary stage.
