Any TECO-Westinghouse Motor Co. (TWMC) motor direct coupled to a reciprocating compressor and operated without first having a system analysis performed will have a voided warranty. Upon request, TWMC will provide a shaft profile drawing (includes shaft geometry, mass elastic data, shaft torsional stiffness, weights, and inertias) and a current pulsation study (crank effort data must be provided by others), in order to allow parties other than TWMC to perform the required system analysis. Contact TWMC for pricing of these adders.
