Problems solved by technology

However, the electric energy received by the motor 13 cannot be converted into kinetic energy by the rotor structure for release, instead it is converted into heat energy to cause the temperature of the motor 13 to rise, so that the motor 13 may be damaged or burned due to overheating, reducing the motor 13 reliability and service life

Embodiment Construction

[0032] A fan system and its protection device according to preferred embodiments of the present invention will be described below with reference to the accompanying drawings, wherein the same components will be described with the same reference numerals.

[0033] Please refer to image 3 As shown, a fan system 2 according to a preferred embodiment of the present invention includes a driving device 21 , a protection device 22 and a motor 23 .

[0034] The driving device 21 generates a first input signal S3 and a second input signal S4, and the first input signal S3 can be implemented as a Hall signal, and the Hall signal can be passed through a Hall IC (Fig. not shown), and the second input signal S4 is an inversion signal of the first input signal S3.

[0035] The motor 23 has a coil set 231 and a rotor structure (not shown in the figure), and the rotor structure is generated by the electromagnetic induction of the coil set 231 to drive the motor 23 to run.

[0036] The prot...

Abstract

A fan system protection device receives a first input signal, and the protection device includes at least one first switch assembly and at least one control unit. The first switch component receives the first input signal; the control unit is electrically connected to the first switch component, receives and controls the conduction or non-conduction of the first switch component according to the first input signal; wherein, when When the first switch component is turned on, the control unit stops outputting the first input signal, and when the first switch component is not turned on, the control unit outputs the first input signal.

Description

technical field [0001] The invention relates to a system and its protection device, in particular to a fan system capable of protecting a motor from damage and its protection device. Background technique [0002] like figure 1 and figure 2 As shown, an existing fan system 1 includes a driving device 11, a switching device 12 and a motor 13, and figure 2 is an equivalent circuit diagram of the fan system 1 . The driving device 11 generates a first input signal S1 and a second input signal S2, and the first input signal S1 is a pulse signal, and a switching element 1111 of an inverter 111 operates to generate the pulse The signal is converted into an anti-phase pulse signal, that is, the second input signal S2, so the second input signal S2 and the first input signal S1 are mutually inverse phases. In addition, the above-mentioned driving device 11 can be a Hall IC (HallEffect IC ), and the first input signal S1 and / or the second input signal S2 can be Hall signals; Sig...
