Abstract

PROBLEM TO BE SOLVED: To reduce windage loss for improvement of efficiency by applying low-viscosity varnish and then high-viscosity varnish at the time of applying varnish to an armature. SOLUTION: To ensure mechanical strength sufficiently high enough to withstand centrifugal force during rotation between coils or the coil and electric insulation by integrating a coil and an iron core 20 with varnish, a sufficient amount of varnish is applied in a slot using low-viscosity varnish. Varnish is then applied to a coil surface at the end part of the iron core 20 again using high-viscosity varnish, so as to eliminate the roughness of the coil surface at the end part of the iron core 20. It is thus possible to reduce the windage of a motor easily and obtain a highly efficient motor.

2. Description of the Related Art Conventionally, in a rotating machine such as an AC commutator motor used for an electric blower or the like, a coil moves due to electrical insulation between armature windings and an armature core, and centrifugal force during rotation of the motor. To prevent the coil from separating from the connection with the commutator due to centrifugal force applied to the coil,
A varnish was applied to the coil and fixed. However, the varnish coating here is intended to integrate the coil and the rotor simply by filling the varnish into the slot and the coil end, to provide strength against centrifugal force during rotation, and to provide electrical insulation. The end surface is filled with varnish,
There was no application so that the unevenness due to the overlapping of the coils at the coil end was eliminated. Therefore, during rotation, a loss (windage loss) occurs due to friction between the unevenness and the air, and the efficiency of the electric motor is reduced.

Conventionally, a thin copper wire has been used for the armature winding. Therefore, both ends of the iron core (hereinafter referred to as coil ends) are coaxial with the rotor and have slots (grooves) for winding coils. However, since the number of irregularities due to the coil overlap at the coil end was small and the number of rotations of the motor was not high, the number of irregularities due to the coil overlap at the coil end was small, and the influence of windage caused by this was small. In order to increase the efficiency of the motor, the diameter of the armature winding has been increased for the purpose of reducing copper loss, the unevenness due to the coil overlap at the coil end has increased, and the rotational speed of the motor has also increased. Wind loss due to coil irregularities has become larger than before, and it has become necessary to reduce wind damage due to coil irregularities at the coil end in order to further increase the efficiency of the motor.

Japanese Patent Application Laid-Open No. Hei 6-233510 discloses a technique for molding the surface of an armature with a varnish as in the present invention. In this example, the entire armature is molded into a substantially columnar shape, and the molded portion is cut to correct the imbalance of the armature, further reducing windage loss and reducing temperature rise. However, unbalance is generally performed by cutting a metal part for balance correction provided coaxially with the armature core or rotor, and correcting the balance by cutting the mold part as in this example Since the specific gravity of resin is smaller than that of metal, the volume to be cut is larger than that for cutting conventional metal parts.To prevent the armature coil under the mold from being damaged, the molded part must be It had to be very large, making it very difficult to downsize the motor.

[0005] Further, regarding the heat radiation, since the air flow on the armature surface is reduced as compared with the conventional one because the windage is reduced, the heat radiation is actually inferior to the conventional one, and more mold material is applied to the armature. As a result, the heat capacity of the armature is increased, and in this example, the temperature rise of the armature coil is rather large.

Japanese Patent Laid-Open Publication No. Sho 62-172247 discloses a method of flattening a coil end with a varnish. In this example, the aim is to reduce the agitation resistance of fuel flowing in an electric motor. Since this is supported by providing a fuel flow path in the armature slot, unlike the conventional varnish coating process on the armature and the present invention which does not make any changes to the armature structure, Could not be implemented. Further, since the number of rotations of the electric motor is much lower than that used in the present invention, no consideration is given to its strength.

Further, in an electric blower used for a vacuum cleaner, the exhaust flow from the blower passes through the inside of the motor, so that the flow velocity around the rotor is high, and the wind flow due to the exhaust flow and unevenness of the rotor surface is reduced. Because of its large size, it was difficult to increase the efficiency of the electric blower.

In the present invention, based on the above, the amount of varnish applied to the armature is set to the minimum amount necessary for reducing windage loss, thereby suppressing an increase in the heat capacity of the armature, and the strength is made higher than before. It is possible to provide a more efficient electric motor by reducing the windage loss by an easier method than the conventional example.

According to the present invention, when applying a varnish to an armature, a varnish having a low viscosity is applied first, and then a varnish having a high viscosity is applied.

In this way, the varnish having a low viscosity applied first can sufficiently turn the varnish between the windings and the slot portion in the armature, thereby integrating the coil and the armature core to secure sufficient mechanical strength. Then, the second time, the unevenness of the coil surface at the coil end is filled with a high-viscosity varnish and smoothed.

The reason why two kinds of varnishes having different viscosities are used here is that the varnish having the same viscosity as that of the conventional varnish having a low viscosity has a low viscosity when the coating amount is increased in order to eliminate the unevenness of the coil end portion. Since the varnish does not adhere uniformly to the coil ends, the effect of reducing the windage loss is not sufficient, and the unevenness of the varnish increases the unbalance of the armature, thereby increasing the rotational speed of the motor. This is because if the angle is raised, vibration may occur. Furthermore, if the flowing varnish adheres to a commutator provided coaxially with the rotor, commutation failure occurs and the life of the motor is significantly shortened. Therefore, the present invention uses two types of varnishes having different viscosities. The unevenness of the coil end is eliminated while ensuring the mechanical strength.

The varnish conventionally used is a coil and an iron core 20 (rotor 6) which are integrated with a varnish and have mechanical strength enough to withstand the centrifugal force during rotation and electrical insulation between the coil and the iron core 20. In order to ensure that the varnish has a low viscosity so that the varnish sufficiently wraps around the inside of the slot in which the coil is wound, the varnish is removed such that the coil surface at the end of the iron core 20 has no irregularities as in this embodiment. If a large amount of the varnish is applied, it flows and cannot be applied uniformly, so that the imbalance of the rotor 6 increases and causes vibration and noise. The raising brush 8 was rapidly worn, and the life of the electric blower 1 was significantly shortened. In this embodiment, the varnish is sufficiently applied in the slot using the same varnish as before, and then the varnish is applied again to the coil surface at the end of the core 20 using a high-viscosity varnish, whereby the coil at the end of the core 20 is applied. Eliminates surface irregularities.

As another embodiment, after winding a coil around the rotor 6, a flexible member, such as felt, which can be impregnated with varnish is wound around the coil surface at the end of the iron core 20, and then varnish is applied. By doing so, the unevenness of the coil end can be easily eliminated. According to this method, it is possible to easily reduce the windage loss of the electric motor without changing the equipment and varnish used for varnish application.

Yes. In this case, if the substantially hemispherical separate members 24a and 24b are attached before applying the varnish, holes 25 are provided on the surfaces of the substantially hemispherical separate members 24a and 24b so that the varnish flows into the coil.

According to the present invention, the method of applying varnish is changed, or the varnish is applied after winding a flexible member, so that the existing equipment for manufacturing an electric blower is hardly modified. Since the windage of the electric blower can be easily reduced, especially when the exhaust of the blower passes through the inside of the motor, such as the electric blower used for the vacuum cleaner, the windage loss between the exhaust flow and the rotor can be greatly reduced. Thus, a highly efficient electric blower can be obtained.
