The invention provides a bidirectional starting device and a motor applying the device and a fan. The bidirectional starting device comprises a torsion spring which is arranged on a rotating shaft ina sleeving way and comprises a first end and a second end which are opposite; two active members which are fixed on a rotor and separately arranged on the first end and the second end of the torsion spring and driven to rotate by the rotor and respectively comprise a driving part, wherein one of the driving parts drives the first end of the torsion spring to rotate in a torsion way relative to thesecond end in case of anticlockwise rotation of the rotor and the torsion spring is enabled to be tightly screwed and drive the rotating shaft to rotate, and the other driving part drives the secondend of the torsion spring to rotate in a torsion way relative to the first end in case of clockwise rotation of the rotor and the torsion spring is enabled to be tightly screwed and drive the rotatingshaft to rotate; and two matching parts which are respectively stopped on the first end and the second end of the torsion spring and fixed relative to the position of the rotating shaft, wherein thematching part arranged on the second end stops the second end of the torsion spring when the first end of the torsion spring rotates in a torsion way relative to the second end, and the matching partarranged on the first end stops the first end of the torsion spring when the second end of the torsion spring rotates in a torsion way relative to the first end. Bidirectional rotation of the fan canbe realized by application of the bidirectional starting device.
Description
【Technical field】 [0001] The invention relates to the field of electric motors, and more specifically, relates to a bidirectional starting device applied to a motor and a motor and a fan using the bidirectional starting device. 【Background technique】 [0002] Such as figure 1 As shown, the existing motor drives the fan to run through the drive assembly 70. The drive assembly 70 includes a drive shaft 71 and a fixing seat 73 fixed on the drive shaft 71 on the side of the motor 50, and includes a fixed seat 73 fixed on the side of the fan 60. The connection seat 75 of the fan impeller. The driving assembly further includes a torsion spring 79 connecting the fixing base 73 and the connecting base 75 . The connecting seat 75 is sleeved on the driving shaft 71, and the torsion spring 79 is sleeved on the connecting seat 75. After the motor 50 is started, the torsion spring 79 tightens the connecting seat 75, so that the connecting seat 75 and the driving shaft 71 There is enou...
