Select the correct ModularAssembly System size.• Using the NEMA Motor/FrameSelection Chart, find the framesize, horsepower and output rpmof the motor you will be using. Thesize of the compatible ModularSystem is shown in the right handcolumn. Make a note of thisnumber.• If your chosen Modular Assemblycalls for a Brake (B), an OutputUnit (O), an Input Unit (I) or acombination of these, consult theOverhung Load Data chart to knowthe limits of the Modular SystemSize chosen.• Review the Thermal Capacity chartto familiarize yourself with therating of your chosen ModularAssembly by Size.• Review the Torque charts toensure your selected System Sizefalls within your guidelines.NOTE: Whenever Modular SystemProduct values are less than youroperational values, move up to a SystemSize to meet your specifications. Movingto a higher System Size may affect motorand frame size requirements.◗ THERMAL CAPACITY DATA (HP T )Standard Modular Systems (Open Design)Modular Assembly RPM 625 875 1125 1375Brake 1800 0.23 0.23 0.33 0.50MBU 1200 0.20 0.20 0.30 0.46Clutch 1800 0.44 0.44 0.53 0.77MDO 1200 0.40 0.40 0.50 0.71Clutch-Brake 1800 0.40 0.40 0.50 0.75MDB 1200 0.35 0.35 0.45 0.70Input Brake 1800 0.23 0.23 0.33 0.50MIB 1200 0.20 0.20 0.30 0.46Input Clutch 1800 0.44 0.44 0.53 0.77MIDO 1200 0.40 0.40 0.50 0.71Input Clutch-Brake 1800 0.40 0.40 0.50 0.75MIDB 1200 0.35 0.35 0.45 0.70245
