Embodiment 1

[0043] refer to figure 2 As shown, the present invention also discloses a fan driving system, which includes a BLDC motor driving system and the above-mentioned claw pole motor driving system, and the BLDC motor driving system and the claw pole motor driving system are respectively connected to a power supply.

[0044]In this embodiment, the BLDC driving system includes a traditional BLDC blade driving motor 4 , a BLDC driver 5 and a BLDC power amplifier circuit 6 connected in series between the BLDC driving motor 4 and the BLDC driver 5 . When connecting, the positive poles of the power supply of the claw pole motor driver 2 and the claw pole motor power amplifier circuit 3 need to be connected in parallel with the positive poles of the power supply of the BLDC driver 5 and the BLDC power amplifier circuit 6 and then connected to the positive pole of the external DC power supply, while the claw pole motor driver 2 and the The negative pole of the power supply of the claw pol...

Embodiment 2

[0048] According to actual needs, the fan drive system described in Embodiment 1 can also be properly adjusted as follows, that is, the claw pole motor driver 2 and the BLDC driver 5 are integrated on one chip to realize, that is, a drive control chip controls the claw pole at the same time Pole motor 1 and BLDC drive motor 4, the structure of which is as follows image 3 shown.

[0049] That is, the positive poles of the claw pole motor power amplifier circuit 3 and the BLDC power amplifier circuit 6 are both connected to the positive pole of the external DC power supply, and the negative poles of the power supply are connected to the negative pole of the external DC power supply. Since the claw pole motor driver 2 and the BLDC driver 5 need to be integrated on one chip, this embodiment is preferably realized by using a COMBO chip. At this time, in order to distinguish it from the previous claw-pole motor driver 2 and BLDC driver 5 , in this embodiment, the COMBO chip integr...

Abstract

The invention discloses a claw pole motor driving system and a claw pole motor driving method used for oscillation of an electric fan as well as a fan driving system applying the same. The law pole motor driving system mainly consists of a claw pole motor and a claw pole motor driver; and a claw pole motor power amplification circuit is connected in series between the claw pole motor and the claw pole motor driver. The fan driving system comprises a BLDC (Brushless Direct-Current) motor driving system and a claw pole motor driving system; and the BLDC motor driving system and the claw pole motor driving system are respectively connected with a power source. The claw pole motor driving system provided by the invention not only is very simple in whole structure, but further can also realize a fan oscillating function with the coordination of a brushless direct-current motor. The claw pole motor driving system provided by the invention has the advantages of very low cost, and convenience in popularization and use.

Description

technical field [0001] The invention relates to a motor drive system, in particular to a claw-pole motor drive system for electric fans to shake the head, a drive method and a fan drive system using the same. Background technique [0002] At present, in many household and industrial electric fans, the function of shaking the head of the fan is essential. The traditional method is to use a single-phase induction motor to drive the electric fan, and use a single-phase claw-pole motor to realize the fan head. Since the single-phase induction motor and the single-phase claw-pole motor can be driven by the same AC power supply, it is very The manufacturing and operating costs of the electric fan are reduced to a great extent, but the efficiency of the electric fan is low and cannot meet the requirements of high efficiency and energy saving. [0003] Since the use of a brushless DC motor (Brushless DC Motor, BLDC for short) can greatly improve the operating efficiency of the elec...
