Can dc motors can be polyphase

WebSep 22, 2015 · Abstract. This paper presents a comparative analysis of the fault tolerance of polyphase motors. Since each phase generates a smaller part of the total torque than in the case of a three-phase machine, it is easier to improve the fault tolerance with a polyphase motor. Previously all commercial motors were DC, with expensive commutators, high-maintenance brushes and characteristics unsuitable for operation on an alternating current network. Polyphase motors are simple to construct, are self-starting and have little vibration compared with single-phase motors. See more A polyphase system is a means of distributing alternating-current (AC) electrical power where the power transfer is constant during each electrical cycle. AC phase refers to the phase offset value (in degrees) … See more In the very early days of commercial electric power, some installations used two-phase four-wire systems for motors. The chief … See more Once polyphase power is available, it may be converted to any desired number of phases with a suitable arrangement of transformers. Thus, the need for more than three phases is unusual, but higher phase numbers than three have been used. See more Polyphase power is particularly useful in AC motors, such as the induction motor, where it generates a rotating magnetic field. When a three-or … See more • Single-phase electric power • Three-phase electric power • Delta-wye transformer See more • Thompson, S. P. (1900).
