The Marathon B317 is a 1/2 HP capacitor start motor for fan and blower applications. It runs at 1725 RPM on 115V or 208-230V single phase, so one motor covers both voltages. Capacitor start gives it high starting torque.

It has a heavy gauge steel frame, a drip proof enclosure and a NEMA 56 resilient base with extended studs, plus a 5/8 in. shaft. Ball bearings and an automatic reset thermal overload round it out. Overall length is 10.32 in. For 3/4 HP, see the Marathon B319.
