Benefits of Braking Resistors
Voltage Suppression
Prevents pump-up voltage spikes, safeguarding VFD components.
Enhanced Braking Performance
Enables rapid, controlled stops for high-inertia loads.
Durability
Handles frequent cycling without performance degradation.
Safety
Critical for applications where delayed stopping risks accidents.
Installation of Braking Resistor
Mechanical Installation
Mount spring-wound resistors vertically. A horizontal orientation may cause the conductor to deform under its own weight, compromising resistance accuracy.
The mounting bracket must be sufficiently rigid. Resistance deviation under vibrational conditions must not exceed ±1%.
Electrical Wiring
Connect the input terminals (A/B) to the power supply or brake unit. Connect the output terminals (C/D) to the load or ground.
Terminals are made of silver-plated copper. Tighten to the specified torque (e.g., 5-6 N·m for M6 bolts).
Types of Brake resistors
Wire-wound resistors
These are a common choice for applications that require high power dissipation, as they can handle large amounts of energy and have good temperature stability. They are often used in industrial applications, such as elevators and cranes, where heavy loads are being lifted and need to be stopped quickly.
Ceramic resistors
These are a good choice for applications that require a small and lightweight braking resistor, as they have a low profile and can be mounted directly onto a circuit board. They are often used in electronic equipment, such as power supplies and motor control circuits.
Metal oxide resistors
These are a good choice for applications that require high stability and reliability, as they have a high tolerance for harsh operating environments, including high temperatures and humidity. They are often used in industrial equipment, such as oil rigs and mining machinery.
Film resistors
These are a good choice for applications that require precise resistance values, as they can be manufactured with high accuracy and low tolerance levels. They are often used in precision measurement equipment, such as medical devices and scientific instruments.
Typical Applications
Energy and Power
Wind turbines, solar inverters, power distribution systems, and resistor cabinets/enclosures.
Industrial Control
Inverters, elevators, lifting equipment, welding power supplies, and automation systems.
Special Applications
Marine propulsion, railway systems, and military-grade equipment.
Maintenance and Best Practices for Braking Resistors
Inspection: Braking resistors should be tested frequently to make sure they are in excellent shape and unharmed by physical defects like corrosion or fractures. Replace any worn-out or broken resistors right away to avoid any safety risks.
Cleaning: Over time, dust and other debris can build up on braking resistors and impact how well they work. The resistors should be cleaned often with a soft brush or compressed air to get rid of any dust or debris that may have built up on the surface.
Testing: Testing brake resistors regularly might assist find possible problems before they become serious ones. The resistor's resistance may be measured through tests with a multimeter to make sure it is operating within the required parameters.
Temperature Monitoring: Monitoring of temperature is necessary to prevent overheating of the braking resistors since they produce heat while they are in use. Temperature sensors can be fitted to keep track of the resistor's temperature and notify maintenance staff if it rises over the acceptable working range.
Replacement: Braking resistors may eventually wear out and need to be replaced. The same kind of resistor that is compatible with the electrical circuit and satisfies the requirements should be used to replace them.
