Braking choppers, sometimes also referred to as braking units, are used in the DC voltage intermediate circuits of frequency converters to control voltage when the load feeds energy back to the intermediate circuit. This arises, for example, when a magnetized motor is being rotated by an overhauling … See more A braking chopper is an electrical switch that limits the DC bus voltage by switching the braking energy to a resistor where the braking energy is converted to heat. Braking choppers are automatically activated when the … See more • Simple electrical construction and well-known technology • Low fundamental investment for chopper and resistor See more Braking choppers are inappropriate when: • The braking cycle is needed only occasionally • The amount of braking energy with respect … See more • Motor controller See more • The braking energy is wasted if the heated air can not be used • The braking chopper and resistors require additional space • May require extra investments in the cooling and heat recovery system See more Flux braking is another method, based on motor losses, for handling an overrunning load. When braking in the drive system is needed, the motor flux and thus also the magnetizing See more Webbraking pulses of individual drives without a need for a brake chopper and resistor. • If you need brake choppers and resistors, they can be optimized for the whole system. You do not have to use the chopper of every drive. • You do not necessarily need to connect every drive to the AC power line. Challenges of the common DC system ... lg appliances at best buy
