From the manufacturer of resistance for electro-glazing: What is the variable frequency converter braking resistor? What is the function of the variable frequency converter braking resistor? 
Electric motors are one of the frequently used equipment in industrial factories. They are the providers of power. Whether in the construction industry or household products, motors are needed. You may not be familiar with motors, but when it comes to motors, you may know what they are. In equipment applications, when motors are working, various speed changes or direction changes are required to achieve certain mechanical purposes. During these processes, a large part of the energy loss is wasted in the form of heat. To reduce waste, people invented frequency converters to control the behavior of motors to save energy. So what is the frequency converter braking resistor and what is its function? The editor of the enamel resistor manufacturer will explain it to you. 
From the manufacturer of resistance for electro-glazing: What is the frequency converter braking resistor? 
The inverter braking resistor is a component used to dissipate the regenerated energy of the motor in the form of heat. It consists of two important parameters: resistance value and power capacity. 
When the motor driven by the frequency converter or other inductive loads stops, energy consumption braking is generally used to achieve the stop, that is, the kinetic energy of the motor and the magnetic energy in the coils after stopping are consumed by another energy-consuming component, thereby achieving a rapid stop. When the power supply is cut off, the inverter circuit of the frequency converter will conduct in reverse and feed the remaining electrical energy back to the DC bus of the frequency converter, causing the voltage on the DC bus to rise. When the voltage rises to a certain value, the braking resistor of the frequency converter will be put into operation, so that this part of the electrical energy will be consumed by the resistor through heat, and at the same time, the voltage on the DC bus will remain at the normal value.

　　Resistor manufacturer: What is the function of the inverter braking resistor? 
What is the function of the braking resistor in a frequency converter? When the motor slows down, the inertia of the equipment becomes too large, causing the motor to act as a generator. This is because it is operating in a power generation state. The motor supplies power in the opposite direction to the inverter, causing an overvoltage alarm in the inverter. To release this energy, the method of increasing the power of the resistor (appropriately reducing the resistance value) is adopted. There is also a circuit that can supply power in the opposite direction to the power source. It is widely used in ordinary DC bus frequency conversion systems. It can save energy, achieve the same braking and power generation effects, prevent the inverter from decelerating and overvoltage, reduce the deceleration distance, and improve dynamic performance. 
The built-in brake in the motor is generally used for the final stop brake, rather than for deceleration braking. This is fundamentally different from resistance braking. Because resistance braking only takes effect during the deceleration process of the motor, and it loses its effect once the motor stops. Therefore, a brake is needed to keep the motor stationary. 
From the ceramic resistance manufacturer: What is the function of the braking unit on the frequency converter? 
The braking unit on the frequency converter is used to consume electrical energy. 
2. When an asynchronous motor operates in the power generation and braking state, the mechanical energy converted into electrical energy in the system accumulates in the DC section of the frequency converter. The voltage in the DC section will rise, and thus it needs to be removed. 
3. If the braking resistor is damaged, either the motor loses its braking function or the inverter is overvoltage; 4. When the asynchronous motor operates at power frequency, it can freely switch between motor operation and power generation. Frequency conversion speed regulation blocks the energy feedback channels for both motor power generation and braking. 
5. That is to say, without the inverter, the energy generated during power generation and during braking would automatically be fed back to the power grid, which is very energy-efficient!
