Motor run-in

With DC power on the board, we were able to spin the 1914 DC water-lifter motor for the first time since what we believe to be the 1940's. After a good show of arcs and sparks, the commutator cleared its throat and the motor ran smoothly with a minimum of sparking. This is a compound-wired motor with two interpoles and four fields, rated 50 Horsepower at 250 volts DC, 1150 RPM maximum speed. The switchboard features a soft-starter consisting of a rotary switch to pick through a series of resistor grids, motor fields are controllable by rheostat.  This will be an excellent piece of equipment to demonstrate for visitors while we work on the steam engine.
