Starting and braking resistors
Product Details
Dynamic Braking resistor (DBR) The dynamic braking is particularly suited for motors driven by inverter. The motor is brought to brake by reducing the power supply, realizing a negative running. The asynchronous device will work as a generator, therefore will supply electrical power. This electrical power is dissipated by an external braking resistor, linked right upstream the inverter, avoiding this way the activation of protections which will result in a block of the very same inverter. The inverter can dissipate the regenerated energy during the AC motor braking up to the 3% of its rated power.
Stator starting/braking resistor This resistor is used for gradual starting with the possibility to choose the torque in relation with the device to start. Suggested for equipments with low starting torque and increasing advancement.
Rotor starting/braking resistor This resistor allows a stepped starting having high starting torque with low and limited starting currents. Suggested for high power motors and to drive equipments with strong inertia and needs of fast accelerations and heavy, long and frequent startings
