Presenting current issues in electric motor design, installation, application, and performance, this second edition serves as the most authoritative and reliable guide to electric motor utilization and assessment in the commercial and industrial sectors. Covering topics ranging from motor energy and efficiency to computer-aided design and equipment selection, this reference assists professionals in all aspects of electric motor maintenance, repair, and optimization. It has been expanded by more than 40 percent to explore the most influential technologies in the field including electronic controls, superconducting generators, recent analytical tools, new computing capabilities, and special purpose motors.(9.94) 9.1 .5.4 Two-Speed Induction Motors Some induction motor operating situations do not require the induction motor to operate at full load except ... motor , speed changing with one winding was performed with a consequent-pole connection, which always produces an approximate 2: 1 speed ratio. ... A circuit that will start a constant-torque consequent- pole motor can be found in Millermaster [37, p.
