Braking resistors can be seen in several electronic circuit designs. In addition to this, there are also some other common elements found in these circuits. Thus, it is very important to understand the function and mechanism of braking resistors to get the best of their design. If you have a look at some of the most commonly found Metal Clad Braking Resistors in electronic circuit designs, you will find out that there are certain common characteristics and functions of all of them.
So, the whole process is known as dynamic braking and in it, the braking resistor is known as a dynamic resistor. Basically, a braking resistor creates a braking force by generating a counter-clockwise rotation to quickly stop or slow the mechanical device. In general, high-voltage resistors are used in dynamic braking because they need the least amount of voltage to create a high-velocity braking force. As a result, the Current Sense Resistor Shunts can be found in electronic devices with low power consumption. On the other hand, they are not very effective when there is a large load in them.
Another factor that you should consider is motor speed variability. Most vehicles come with a gear ratio between one and four. This ratio determines the maximum and minimum motor speed that the car will go through. When this ration is disturbed due to some external force, then the vehicle can experience sudden deceleration. So, you should make sure that you don't put any irregularity into the motor speed so that your braking resistors can work effectively.
Finally, you should also choose a resistance level that suits your application needs. Commonly, there are two main classes of braking resistors available in the market. These are standard and variable-frequency drives. Standard drives only require two power signals to control the speed of the drive unit. Meanwhile, variable-frequency drives require three power signals to maintain the frequency of the motor.
For getting the best performance from your braking resistors, you should make sure that you use the right amount of voltage and the correct voltage level. This will allow you to reduce power consumption by adjusting the voltage. Moreover, you should also make sure that you use the right duty cycle of your proposed works circuit. The duty cycle refers to the time it takes for a power train to complete its function. If you want your proposed works circuit to have a long duty cycle, then you should use a lower value of voltage and a higher value of frequency.
