Earliest commercial Tesla motor developed by Westinghouse in 1895
Earliest commercial Tesla type motor developed by Westinghouse engineers is pictured above. Introduced about 1985, this two-phase 200-volt wound-rotor machine had resistances attached to ends of each stator bar. Manually operated multiple-contact (32) rotary rig was used to short resistances when motor attained full operating speed.
