TM 5-3895-374-24-1 Options Braking power calculation - High inertia machine, non-driving load Braking torque on deceleration Cb = J Dw N m, Dt J :total moment of inertia referred to the motor shaft in kg m2, Dw: speed difference in rad/s, Dt: deceleration time in seconds Instantaneous braking power Pb= Cb w in W Average braking power during deceleration Pbd = 0,5 Cb Dw in W Average braking power during one cycle Pbm = Pbd t in W T t braking time in s, T. time of one cycle in s speed - Driving load, continuous operation of unspecified duration Braking is treated as continuous braking Pb = Pbm = Cb w in W, Cb braking torque in N m, w speed in rad/s CAUTION  whatever the application, the instantaneous braking power necessary must be < 1,5 the rated power of the speed controller Braking resistance selection The braking resistance is defined by its ohmic value and power dissipation capacity Ohmic value of the resistance Reference  ATV-452 U40S 075(M)(N) U55(N) U40M D18N U55M 015M D55 D75N 075 U15(N) U75(N)(S) D15(N) D22(N) U75M 037 D90N D90 U22(M)(N) D11(N) D30S D30(N) D11M D55N U30 D15S D37N U40(N) D55S Minimum value 100 47 27 22 15 10 8 7 5 4 of the resistance (W) Power of the resistance rated Pn power that can be dissipated continuously, it must be greater than the average braking power Pbm, - maximum Pmax power that can be dissipated over a short period on intermittent duty, it must be greater than braking power Pb (page 3-215)
