Retarders serve to slow vehicles down, or maintain a steady speed on inclines. They are usually not capable of bringing vehicles to a standstill, as their effectiveness diminishes at low speeds. They are usually used to slow vehicles down, with the final braking being carried out by a friction brake. As the friction brake does not then need to be used so much, particularly at higher speeds, the service lifetime of friction brakes is enhanced.

Radial Clearance Eddy-current Retarders are specifically designed to be used in long-distance sigh seeing cars between 8 meters and 10 meters. They are light in weigh, and easy in installation and maintenance. With a small moment of inertia of rotor and low electric power consumption, they wont increase the burden of the cars. Output torque matches the type of the car, so they have the obvious effects of slowing down. At the same time, they can effectively reduce the friction of service braking system, prevent the overheating of wheel boss, and avoid the flat tire.
