DECLARATION OF CE CONFORMITY AND INCORPORATION WE: WARNER ELECTRIC EUROPE S.A.S. 7, rue Champfleur, BP 20095, F-49182 St Barthélemy d’Anjou Cedex declare under our sole responsibility that all products in this catalogue are exclusively designed for incorporation into a machine or to be assembled with other machines...

The sizing of a Warner Electric clutch or brake depends on various factors. The most common of these factors are shown below in chronological order: • Transmissible torque: In Nm • Energy source: Electric, Pneumatic, Hydraulic, or Mechanical • Actuation mode: Static or Rotating • Operational environment: Oil, Dry or Mixed • Heat dissipation: Duty Cycle, Inertia, Speed, etc. • Orientation of mounting: Horizontal, Vertical, Inclined The majority of applications can be computed using the formulas and calculation methods given below. For special cases we recommend that you contact...

Total Inertia This is the sum of all rotational and reflected inertia's (including the inertia of the clutch or brake parts). 3) Time to accelerate or decelerate Md = ( Jtotal • n ) / ( 9,55 • t ) where: Md = acceleration/deceleration torque in Nm Jtotal = total inertia in kgm2 n = speed of clutch or brake shaft in min-1 t = acceleration / deceleration time required in s 4) Time to accelerate or decelerate Mttl = Md ± M, total d l (except lifting, for this kind of application, please contact us) where : Mtotal = in Nm Ml = static torque in Nm Md = acceleration/deceleration...

- M, = static torque for clutch in Nm + M, = static torque for brake in Nm n = clutch or brake speed in min-1 For vertical motion from top to bottom + and - are reversed Torque limiter W = Md • n • t / 9,55 where: W = in Joules Md = slip torque in Nm n = speed in min-1 t = slipping time in seconds Using the results obtained, verify the heat dissipation using the diagrams shown with each product to see if the product selected meets this requirement.
