Abstract: A side stand magnetic motor and a cooling fan using the side stand magnetic motor are disclosed and are related to telecommunications device accessory technologies, so as to provide a motor that can effectively and fast dissipate heat generated by a coil of the side stand magnetic motor. The side stand magnetic motor includes a stator, where the stator includes a body and a coil disposed on the body; the magnetic motor further includes an engine base for fastening the stator, a thermally conductive structure of a heat transfer material is disposed on the stator, and the thermally conductive structure is in contact with and is connected to the engine base.

Abstract: A fan control method, apparatus, and system, so as to implement speed regulation and rotation direction control on a four-wire system counter-rotating fan with a conventional four-wire fan interface by using a PWM control bus. The method provided by the embodiments of the present invention includes: receiving a first fan regulation and control signal sent by a system control module; converting the first fan regulation and control signal to a forward-rotating control signal, a counter-rotating control signal, or a rotation direction switchover control signal according to a duty cycle range of the first fan regulation and control signal and a current rotation direction of the fan; and sending a control signal obtained by the conversion to a fan driving module, so that the fan driving module drives, according to the control signal obtained by the conversion, the fan to operate.
