8 8I9 INTORQ I BFK470 sprig-applied brake mm 50 Fuctioal priciple B BFK470 sprig-applied brake BFK470 sprig-applied brakes are sigle-disk brakes with two frictio surfaces. Whe deeergised, several sprigs are used to geerate D the brakig torque through frictio lockig. The brake is released electromagetically. Durig brakig, the sprigs use the armature plate to E press the rotor (which ca be shifted axially o the hub) agaist the couter frictio face. Whe the brakes are applied, a air gap S L is preset betwee the armature plate ad the stator. The F stator's coil is eergised with D voltage i order to release the brake. The resultig magetic flux works agaist the sprig force to draw the armature plate to the stator. This releases G the rotor from the sprig force ad allows it to rotate freely. Fixig screws Flage Stator Rotor Hub rmature plate Sprig H Noise-reduced alumiium rotor The rotor with plastic sleeve reduces the rattlig oises i the rotor/hub coectio. t the same time, this icreases the service life of this coectio.

9 haracteristic torques Geeral iformatio INTORQ brakes are dimesioed so that the specified characteristic torques ca usually be achieved reliably after a short ruig-i period. However, as the orgaic frictio liigs used do ot all have idetical properties ad because evirometal coditios ca vary, deviatios from the specified brakig torques are possible. These must be take ito accout i the form of appropriate dimesioig toleraces. Icreased breakaway torque is commo i particular after log dowtimes i humid eviromets where temperatures vary. If the brake is beig used o frictio surfaces provided by the customer, the characteristic torque must be checked. If the brake is to be used solely as a holdig brake without dyamic load, the frictio liig must be reactivated at regular itervals. Frictio liig qualities Various frictio liig qualities are available for differet uses ad areas of applicatio: ST Stadard frictio liig WR Frictio liig with low rate of wear HF High frictio coefficiet frictio liig for high brakig torques RIF Ru-i-free frictio liig, does ot require a ruig-i period HT High-temperature frictio liig, temperature resistat ad suitable for high frictio eergies The characteristic torques listed i the table apply to the stadard (ST) ad low-wear (WR) frictio liigs. The other frictio liigs are used primarily i holdig brake ad emergecy stop applicatios. With the HF ad RIF liigs, it is also possible to achieve higher characteristic torques. haracteristic torques Size haracteristic torque M k [Nm] Reductio of characteristic torque at specified speed to x% ST/WR operatig brake ST/WR/RIF/HT holdig brake 2) HF/RIF holdig brake 3) 1500 [r/mi] 3000 [r/mi] max /50/60 1) 40/50/60 1) /65/70/75/80/100/110 > % 73% 67% 16 55/80 1) 55/80 1) /90/100/105/125/150 > % 73% 67% /150 1) 100/150 1) /165/185/200/235/250 > % 73% 67% 1) Stadard characteristic torques 2) HT frictio liig is approved for use up to 100 Nm for size 14, ad up to 125 Nm for size 16 ad up to 235 Nm for size 18 3) oly for projects; cosultatio required with INTORQ

The specified operatig frequecy S h results i the permissible switchig eergy Q smax. Higher speed ad switchig eergy values icrease wear, because the frictio surfaces are briefly subjected to very high temperatures. The frictio eergy that ca be withstood up to the wear limit of the brake is depedet o a umber of factors: i particular, the iertias to be braked, the brakig speed, the operatig frequecy ad the resultig temperature o the frictio surfaces. I additio, icreased wear should be expected with a vertical brake shaft. Where the amout of frictio eergy per switchig operatio is low, the brake's mechaical compoets ca impose limitatios i terms of service life. I particular, the rotor/hub coectio, sprigs, armature plate ad cylidrical pis are subject to operatioal wear. The expected service life of the stadard desig is aroud 1 millio load alteratios. Solutios that are optimised i terms of service life are available i cases where a loger service life is required (cosult the maufacturer). Maiteace Brakes are compoets which are subject to a great deal of wear. Whe istallig the brake, it must be esured that it ca be easily accessed for ispectio ad maiteace purposes. Itervals betwee ispectios should be set i accordace with the expected service life ad load. For more iformatio, please see the operatig istructios.
