ABB’s new ACS800-11 variable speed regenerative drives capture braking energy from electric motors. They return it in to the network as free electricity, significantly improving energy efficiency. In industry, electric motors are often used in applications with frequent brake applications. A braking chopper and external electrical resistors dissipate braking energy as heat. Resistor braking often […]
According to Omron Automation, it makes good business sense to use regenerative drive technologies on motor loads to reduce a machine’s energy consumption. Studies show that Omron’s regenerative drive solutions can reduce electrical energy consumption by up to 50%, according to the application. Omron tunes its regenerative drive units specifically to match […]
In addition to providing variable the speed of motors, inverter drives can also be used to stop them quickly by applying a braking torque to the motor. The energy released during this process is normally absorbed by a braking circuit and dissipated through braking resistors in the form of heat However, regenerative variable […]
Altivar Active Front End (AFE) for ATV61 and ATV71 An increasing number of AC drives are controlled by inverters. This, combined with the other electronic control technologies can make harmonics a major issue for industrial customers. An Active Front End from Schneider Electric is used to reduce the mains current harmonics as […]
ABB regenerative drives give big payback on downhill conveyors. Using ABB regenerative AC drives fed 520,000 kW of power back into the mains and significantly reduced maintenance costs by improved control on two limestone conveyors used in cement making. Continuous raw material flow is important in cement making and when processing […]
