Electric Motors – Single Phase, Split Phase
An early mid 20th century, split phase, induction motor, speciality engineered, Canadian built for the automatic oil burning, winter air conditioner market, equipped with torsion, vibration rubber insulating mountings, bronze sleeve bearings and characteristic extended oiler tubes with snap caps, it would serve as a marker of best practice in motor production for belted fan applications for the winter air conditioner, heating market during its period of rapid expansion following W.W.II, Leland, Circa 1956.
Features:
– Original shop repair service tag in Howard Oliver’s hand writing “for sale or service, $20.00”
– Original manufactures instructions.
Technical Significance:
– The Leland KS would model the best in FHP motor engineering design for belted fan duty operations on centrifugal fan applications for winter air conditioners, throughout the 1950’s and 60’s, in Canada. Typically mounted on top of the fan in a floating harass, the motor would be in the cool return air stream, serving to prevent over heating, and allowing relatively compact, heat emitting body designs
– The belted fan configuration with variable speed pulley [see Group 12.11 artifacts] would give way to direct drive, axial mounted motors with electrical speed control for use on centrifugal fans by the end of the century
