Abstract
The present invention relates to a noise-free tapped speed changing circuit of a motor, which has uniform distribution of magnetic force line, and with the speed changing circuit, the running noise of the motor can be reduced to the minimum. The present invention is composed of a running coil, a speed changing coil for starting, and a starting capacitor, wherein in the state of speed reduction, the speed changing coil for starting has a winding method that the coil is wound pole by pole in an equal turn number; the coil is wound for three times and is tapped; after a starting running coil is formed, a speed changing coil in the preset number is wound pole by pole. In this way, each stage of speed changing coil for starting is set into an equal number and can generate uniform magnetic force lines with the running coil, and thus, current direction and the direction of magnetic force lines are consistent in both the state of intermediate speed and the state of low speed.
Description
The present invention relates to a kind of method of making the motor gear box circuit, particularly relate to a kind of magnetic line of force of making and distribute more even and make the motor operation noise reduce to the method for minimum noise-free tapped motor gear box circuit.
General ceiling fan, it can be divided into two kinds on motor gear box: a kind of is the electric capacity speed change, and another kind is a tap speed change.
Ceiling fan with the electric capacity speed change, though noiseless in the use generation, but the price of capacitor is not cheap, and each grade speed change all must be used the capacitor of different numerical value, increased the cost of ceiling fan, and when using the electric capacity speed change, wherein electric capacity, resistance, the triangular phase angle of electric current and unstable make the motor elevated temperature easily.
And concerning the mode speed change of tap, Fig. 1,2,3 shows the distribution scenario of existing tapped varying speed motor on the market its magnetic line of force when using high, medium and low speed shelves to turn round and the tap winding diagram of coil respectively.
As shown in Figure 1, ceiling fan motor is under the situation that runs up, as the sense of current with each coil, drawing magnetic line of force distribution scenario with the right-hand rule (be that the right hand is held coil, thumb points to magnetic north pole, all the other four finger expression senses of current) can find, run up when using, because the magnetic line of force of motor stator is evenly distributed and symmetry, so the galvanomagnetic effect of its stator and rotor will be quite satisfactory, quite stable during running and noiselessness.
But, in switching to or during low speed, shown in Fig. 2,3, drawing magnetic line of force distribution map according to the direction of coil current can find that motor is when middling speed or low-speed running equally, because the direct centre tap of motor winding, the direction that makes coil current partly is with opposite when running up, thereby makes the symmetrical originally magnetic line of force, and moment changes over irregular phenomenon, so motor not only is easy to generate noise in running, and unstable.
Find by the gear shift mode of above two kinds of ceiling fan motors, in the mode of electric capacity speed change, though noiselessness costs an arm and a leg and is easy to generate high temperature.And in the mode of tap speed change, though comparatively economical, be easy to generate noise.
