PerformancePlus lectro Packs with ceramic friction material are rugged, preassembled clutch and brake combinations in base mounted housings. They have been designed to be installed in standard power transmission systems with V-belts and pulleys, chain and sprockets, in line couplings, and timing belt drives. When your application calls for a long life clutch/brake because of high cycle rates or demanding consistency, choose the PerformancePlus solution. olt-it-down and wire-it-up... it s ready to go! vailable in two size; 170 and 250.

When used with a -700 over-excitation control and programmable counter, exceptional closed loop clutch/brake performance can be achieved approaching that of more expensive motion control technologies The PerformancePlus difference! Selection PerformancePlus lectro Packs are best suited for high energy applications where long life is a premium concern. The harder a ceramic friction surface is worked, the more wear life benefit is achieved. For slower cycle rates, up to 75 cycles per minute, dependable standard clutch/brakes are still a good choice. Typical pplications Form, Fill and Seal The PerformancePlus lectro Pack provides high cycle rate indexing for packaging and bagging operations. For high cycle rates and high energy use (generally more than 50 cycles/minute for P-170 s and P-250 s) PerformancePlus clutch/brakes are the choice. Technical considerations for sizing and selection are torque and heat dissipation. ach merits careful consideration, especially heat dissipation. Over temperature use will have an adverse effect on bearing life and coil wire insulation integrity. For proper sizing information, refer to the orsepower vs. Shaft Speed chart, and the technical sizing considerations below.

9 lectro Pack eramic Faced Selection/Ordering nformation P- Series eat issipation Sizing Friction surfaces slip during the initial period of engagement and, as a result, heat is generated. The clutch/brake selected must have a heat dissipation rating greater than the heat generated by the application. Therefore, in high inertia or high cycle rate applications, it is necessary to check the heat dissipation carefully. nertia, speed and cycle rate are the required parameters. These curves show the heat dissipation capability of the ceramic units. P-170- eat issipation (ft. lb./min.) aximum Speed 7500 rpm P-250- eat issipation (ft. lb./min.)

Static Voltage Size RP Torque P , lb. in. 24 & 90 P lb. in. 24 & 90 For some applications, the torque requirement is determined by the time allowed to accelerate and decelerate the load. (This time is generally specified in milliseconds.) For these applications, it is necessary to determine the torque requirement based on load inertia and the time allowed for engagement. The torque requirements are calculated as follows: T = WR 2 x 308 x t where: T = verage ynamic Torque (lb. ft.) (For P selection, multiply by 12 to convert to units of lb. in.)
