Polyphase motor
WebOct 1, 2012 · The Gramme motor/generator that Tesla saw while attending the Graz Institute of Technology had a construction like the one shown in Fig. 1 . The stator consisted of a horse-shoe magnet and the rotor was a ring-type armature. To use it as a motor, electric current is supplied to the armature through the brushes. WebThe great advantage of polyphase motors is, for a given number of poles, a smoother, more intense whirling field; such motors, in myriad forms, launched the electrical age of heavy industry.

WebAug 22, 2024 · A synchronous motor is a doubly excitation machine, i.e., its armature winding is connected to an AC source and its field winding is excited from a DC source. An induction motor is a singly excited machine, that is, its stator winding is energized from an AC source. Speed. Its speed is independent of the load. WebScope: This standard covers instructions for conducting and reporting the more generally applicable and acceptable tests of polyphase induction motors and generators. Many of the tests described may be applied to both motors and generators, as needed, and no attempt is made to partition the test procedure into clauses and subclauses that separately apply to …
