Greetings; I have a couple of quick questions concerning this old Westinghouse DC motor. It was originally installed in the Carnegie Music Hall in Pittsburgh, PA in 1895, to power a lift mechanism that allowed the pipe organ console to rise up to stage level. The motor is 4 pole, 2 brushes at 90 degrees, one single winding in each field coil, and is supposed to run at 1200 RPM, at 110 VDC. The end of the armature is stamped "2 HP". The latest patent date on the ID plate is 1892. Does anyone know how to hook this motor up? Is it a series or shunt motor? I have no controller for it, and never found the original. I used to service the pipe organ there, at Carnegie, until they quit using it about 15 years ago. Is there any way a power supply could be built so this motor could run? Thank you!, from Pittsburgh, PA.
