The TR series includes 4 models. Compact structure, light weight, small size, easy to disassemble and assemble; The rotor adopts a cylindrical structure, a fully machined surface, and a beautiful appearance; Low power consumption, no need to replace the original car generator; The braking torque is large, 100-300NM larger than other similar structure eddy current retarders, and the maximum braking torque can be reached at low speed (vehicle speed is about 15km/h); Radial distribution, so that the rotor gap is not affected by the bearing movement, making the eddy current retarder run more reliable and more widely matched; The axial length is small, the weight of the rotor is light (about 20kg), and the impact on the original vehicle’s transmission system is small; The installation space required is small, especially suitable for medium-sized vehicles with short rear suspension and unable to shorten the drive shaft; Adopt digital and intelligent control system, safer work and more reliable operation.
