• 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.
