8 CONTINUOUS PWER CURVES E28 DIAMETER FRAMES Standard E28 frame motors are limited (mechanical design) to 36 RPM. Special designs are available that allow operation to speeds indicated in the individual curves. DPBV DRIPPROOF BLOWER VENTILATED Horsepower kw One power curve is shown for each stack length in both the DPBV and TENV enclosures. Four different winding connections are offered for each stack length, but the power curve is the same for all connections. Therefore, only one power curve is necessary for each stack length and enclosure. TENV TOTALLY ENCLOSED NON-VENTILATED Horsepower kw Horsepower kw Horsepower kw Note: see Motor Performance Curves, page

9 EFFICIENCY CURVES E28 DIAMETER FRAMES One efficiency curve is shown for each stack length. Efficiencies for the DPBV and TENV enclosures are approximately the same, so a single curve represents both. In addition, although four different winding connections are offered for each stack length, the efficiency is the same for all connections.
