Technical description Powder brakes and clutches make it possible to design drives where the (braking) torque may be adjusted smoothly (programmed), as needed by the user, from the minimum value Mr (residual torque Mr <= 1% Mn), up to the rated torque Mn (Table). Upon engagement, the torque is smoothly increased with a certain delay t09 [ms] (the time for reaching 90% of Mn), and upon disengagement the torque decays, also smoothly, with a delay t01 [ms] (the time for reaching 10% of Mn), whereas its value depends (almost linearly) on the coil current value (see charts). For braking torque adjustment,...

* - with controller EZP-51 ** - Heat loss power at 100% operation (To =20oC) : P = 0,105 * Mh [Nm] *(nw - nk) [min-1] < Pmax nw - rotor speed [min-1] , nk - clutch body speed [min-1] , lub P = F [N] * V [m/s] < Pmax t09 - the time for reaching 90 % Mn upon engagement , t01 - the time for reaching 10 % Mn upon disengagement
