摘要： A serial multiplexer module for server management includes a first, a second and a third switching devices in circuit connection with a baseboard management controller, a serial transceiver and an input/output controller respectively. Each of the switching devices includes respectively four simplex sub-switches. The simplex sub-switches are controlled to be switched on/off directly/indirectly by a first control signal and/or a second control signal transmitted from the baseboard management controller, thereby enabling and monitoring the communication between the baseboard management controller, the input/output controller and the serial transceiver.
摘要翻译： 用于服务器管理的串行多路复用器模块包括分别与基板管理控制器，串行收发器和输入/输出控制器电路连接的第一，第二和第三开关装置。 每个开关装置分别包括四个单工子开关。 单片子开关被控制为通过从基板管理控制器发送的第一控制信号和/或第二控制信号直接/间接地接通/断开，从而实现和监视基板管理控制器，输入/ 输出控制器和串行收发器。

摘要： A fan motor includes a pair of fans axially mounted to both sides of a rotary shaft of the motor. The motor includes an inner rotor placed inside a stator wound with windings and an outer rotor placed outside the stator. The motor thus has a dual-rotor structure where the inner rotor and the outer rotor are held such that both the rotors can rotate on the rotary shaft.

摘要： A motor stator of the invention is provided with a laminated stator core comprising a plurality of core pieces having teeth and linked by intermediate thin-wall portions. The thin-wall portions are bent to form the stator core into an annular shape with two ends of the stator core joined by welding, and slots are formed between adjoining pairs of the teeth. A welded portion of the stator core is not near a center line in a radial direction of any of the slots.

摘要： A motor includes a stator with an annular stator yoke, a stator core having a plurality of inner and outer teeth projecting from the stator yoke toward inside and outside respectively, a plurality of coils wound on the stator core, and an inner rotor and an outer rotor confronting the inner and outer teeth respectively via an air-gap, and having an permanent magnet respectively. The number of slots “S” and the number of poles “P” establish a relation of S:P=3:2N−1, where N is an integer equal to 1 or more, and a case when 2N−1 becomes a multiple of 3 is excluded.
