Inverter braking resistor
Dec 19, 2017

Inverter braking resistor can be used in the inverter to control the motor deceleration and braking circuit, usually an external resistor can be consumed from the motor and load the excess energy to protect the inverter over-voltage protection. In the industrial system, the inverter braking resistor is widely used in motor starting brake speed control, inverter braking, lifting large machinery brake, material handling agencies braking and other fields. They can be intermittent cycle and continuous work.


Inverter braking resistor is used to heat the motor regenerative energy consumption of the carrier, which includes the resistance and power capacity of two important parameters. Usually used in the engineering are more ripple resistance and aluminum resistance of two: Corrugated surface corrugated resistance is conducive to the use of vertical heat to reduce the amount of parasitic inductance, and the choice of nano-silicone coating to do the surface coating, non-toxic odorless, green Environmental protection, safety and reliability, effective protection of resistance wire is not aging, to extend the service life, Beijing Jiaying Technology Co., Ltd. original configuration is such a resistor; aluminum resistance, high heat dissipation of the aluminum alloy package; tight, Sealed filler material is very easy to heat; has strong resistance to weathering and vibration; small size, high power, overload capacity; easy to install and stable, beautiful appearance.

When the inverter works normally, the brake circuit will not work. Only when the load inertia short-circuits greatly, the DC link voltage will exceed the set limit, the brake unit will start to work. The DC voltage will be reduced to the inverter frequency through the brake resistor The brake circuit will stop working when the setting is below the limit. Inverter built-in brake unit, the brake unit action, only measured in the braking resistor braking voltage. External braking unit connected to the positive and negative poles of the DC power supply of the inverter. When the DC voltage exceeds the set voltage, the brake unit works to output the braking voltage to the braking resistor.
