What does a retarder do?

The role of retarder is mainly reflected in the following aspects.
First of all, for large vehicles such as trucks and buses, the retarder can be activated when decelerating or going down a long slope, which can smoothly slow down the vehicle and avoid the wear and heat caused by using the brakes. Just like a car in this situation, the retarder can energize the excitation coil of the stator assembly through the control circuit to generate a magnetic field, and the rotor assembly rotates at high speed with the vehicle's transmission part, cutting the magnetic lines of force and generating a reverse torque to slow down the vehicle. Moreover, the retarder utilizes liquid damping to produce a slowing effect, which can make the vehicle decelerate more smoothly.
Secondly, retarder can improve the efficiency of the transmission system, reduce energy consumption and operating costs. At the same time, it disperses and reduces the stress on the transmission system, reduces the risk of wear and damage, and extends the service life of the equipment.
Further, in emergency braking situations, retarders can help slow the vehicle to a stop and improve safety. It can also reduce the vehicle's traveling speed and vibration, enhancing passenger comfort.
In addition, retarders can adapt to different working conditions. The speed and torque output can be adjusted according to different application scenarios and needs to meet the requirements of various mechanical equipment.
In transportation, such as cars, trains, bicycles, etc., retarders are used to slow down and stop, working with tires, brake pads or drums to reduce friction and generate braking force.
In industrial machinery, such as cranes, excavators, conveyor belts, etc., retarders are used to reduce speed and prevent overloading, protecting the machine from damage and ensuring safe operation.
In electrical systems, such as elevators, fans and pumps, retarders regulate the speed of motors to meet different needs.
In computer hardware, retarders are used to temporarily store data for later processing, improving system performance and efficiency.
In electronic equipment and circuits, retarders are used to slow down the transmission of signals to prevent data loss or errors.
In the biomedical field, retarders can be used to control the rate of drug release for more precise drug dosing, and can also be used to control the speed at which laboratory equipment operates.
Automotive retarders are used when the vehicle ignition is on standby. Need to slow down, trigger the manual switch handle step by step to the required gear can achieve the purpose of slowing down, the hand switch handle back to 0 gear, the withdrawal of retardation command. However, it should be noted that the hydraulic retarder is an auxiliary braking device, can not replace the service brake and parking brake, in case of emergency braking situation, we should decisively use the active braking. When using the hydraulic retarder, be sure to increase the braking force step by step, not from zero gear directly to the highest gear, and do not overstep the use of hydraulic retardation gear.
