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.

Side stand magnetic motor and cooling fan using side stand magnetic motor

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.
