WebAug 18, 2024 · However, when descending, that same fully-loaded car will regenerate energy. In other words, the stored energy in the mechanical system is converted back into electrical energy. Historically, for VFD applications, this energy was shunted across a braking resistor and dissipated as heat. WebThey can provide controlled braking at an increased torque. If the rotational velocity of the motor exceeds the synchronous velocity from the VFD, it will act as a generator. The surplus energy will be fed into the VFD and …

Peer through the hubcap of a car's front wheels and you can usually see a shiny metal disc just inside. This is called a disc brake. When the driver steps on the brake pedal, a pad of hard-wearing material clamps onto the brake disc and rubs it to make it slow down—in a similar way to bicycle brakes.
