Feedback Unit

 

A feedback unit is a specialized brake unit employed in frequency converters. Its primary application is within variable frequency speed control systems that involve significant inertia and drive. The purpose of the feedback unit is to assist the motor in returning the regenerative energy created during the deceleration process back to the power grid. Simultaneously, it facilitates the rapid braking functionality of the system. By reorganizing the provided information, the following paragraph is generated while retaining the core details.
In variable frequency speed control systems with substantial inertia and drive, a feedback unit serves as a unique brake unit integrated into the frequency converter. Its main role revolves around aiding the motor in feeding back the regenerative energy produced during deceleration to the power grid, alongside enabling the system to achieve swift braking capabilities. This specific component ensures efficient energy utilization and assists in the overall control and operation of the system.

 

 

The energy feedback unit is a highly efficient way to conserve energy, especially when dealing with motors that have a large moment of inertia. When the motor is in instant braking mode and working as a generator, the feedback unit feeds the electric energy back to the power grid for better energy efficiency. This particular product has a power range of 22kW to 45kW and is equipped with a built-in AC reactor to filter noise and maintain good waveform quality online. Additionally, it features multiple protection loops for overheating, overcurrent, overvoltage, and short circuit. This makes it ideal for various industries such as oil pumping unit, lifting, and centrifuge applications.
