Braking Resistors: When You Need One
A braking resistor is a vital part of a motor control system. Its main function is to aid a motor in slowing down or coming to a full stop. It also prevents motors from experiencing more damage than is necessary and can increase the life cycle of a motor.
What is a Motor Brake Resistor?
A brake resistor works to slow down and bring a motor to a stop. The energy released by the motor as it slows down is also dispersed by the braking resistor. The energy is dispersed as heat. This is done to ensure that the drive is not damaged as the voltage rise is regulated.
When is a Braking Resistor Needed?
There are a few reasons and problems that indicate one should consider installing a braking resistor:
- An overvoltage causes the drive to constantly trip.
- A visible negative impact on the life expectancy of the equipment.
- An increase in maintenance costs.
- Visible damage that is or has occurred to the drive and/or motor.
Types of Braking Resistors
There are many different types of braking resistors; however, at EP Normand we stock two variations.
The T300 Brake Resistor
This brake resistor is suitable for frequency converters, DC drives, as well as hospital and theatre applications. It is suitable to be used in hospitals and theatres because of its low-noise variation.
Some other features include:
- It can be integrated into the necessary power supply units
- It is equipped with load resistors that are suitable for supply units, power packs, generators, UPS units, and more.
- It is fitted with load resistors that aid in the loading and disloading of capacitors.
- It also features protective resistors.
The T600 Brake Resistor
Much like the T300 model Brake Resistor, this brake resistor is suitable for frequency converters and DC drives; however, it is not available in a low noise option but is suitable for various railway applications.
The features on the T600 range of Brake Resistors are similar to those of the T300 range; however, there are a few extra perks:
- A DC motor starting resistor.
- A starter resistor that is suitable for a squirrel-cage motor.
- It is fitter with starting and regulation resistors that are suited for a slip-ring motor.
- A discharge resistor that is applicable to batteries.
- It also has earthing resistors that are used for low-voltage mains supplies.
