Design of a two horse power Repulsion Start Induction motor

Joseph Worley

Abstract

"The Repulsion Start Induction motor comprises a wound field or stator of laminated structure and a wound armature or rotor whose coils are connected to a commutator upon which brushes bear and function during the starting period. This motor operates as a repulsion motor during the starting period and at a predetermined speed the short circuiting device actuates and short circuits the commutator. The motor then operates as an induction or squirrel cage type. The starting torque of this type of motor is exceptionally high, generally 300% to 400% of full load torque. Consequently this type of motor is regarded as having a high efficiency at start. The starting current is low which causes very little line disturbance. Due to this characteristic, this motor is recommended for general use by the Central Stations. Due to the high starting torque characteristics, this motor is well adapted for applications such as air compressors, baker's machinery, concrete mixers and refrigeration service"--page 1.
