Abstract
The invention discloses a wrapping process for manufacturing a stator coil of a large asynchronous high-efficiency motor. The wrapping process is characterized in that the stator coil of the motor is wrapped in a mixed interlayer wrapping mode by using a TH-1 type mica tape and a TH-2 type mica tape which are different from each other. Through the utilization of a novel coil manufacturing process means, the mechanical property and voltage resistance level of the coil are improved, and the insulation thickness of the stator coil of the motor is reduced, so that the aims of reducing the size of the motor, increasing the capacity of the motor, improving the efficiency of the motor, reducing the cost, saving the energy and promoting greening and environment friendliness are achieved. The market competitiveness of the product is improved.
Description
Technical field
The present invention relates to a kind of coil of stator of motor manufacture method, relate in particular to a kind of wrapped method of insulation that Large Efficient coil of stator of motor is manufactured.
Background technology
The wrapped mode of conventional motors stator coil main insulation is single material wrapping (as shown in Figure 1), and this wrapping mode easily exists in short-term the shortcomings such as withstand voltage low, insulating impregnating varnish poor permeability, low, the electric aging of mechanical strength be poor.And adopt the new wrapped mode of coil of stator of motor main insulation (as shown in Figure 2), there are the advantages such as good mechanical property, withstand voltage properties are good, insulating impregnating varnish good penetrability.
Summary of the invention
To overcome the wrapped method of traditional stator coil (as shown in Figure 1), easily there is in short-term the shortcomings such as withstand voltage low, insulating impregnating varnish poor permeability, low, the electric aging of mechanical strength be poor in the wrapped method that the object of the invention is to provide the manufacture of a kind of Large Efficient coil of stator of motor.
To achieve these goals, the novel insulating wrapping method that a kind of Large Efficient coil of stator of motor of the present invention is used, is characterized in that: coil of stator of motor is wrapped up in the mode of two kinds of different mica tape mixing interlayer wrappings.
Described different mica tapes are to select TH-1 type mica tape and TH-2 type mica tape.Described mixing interlayer wrapping is to take TH-1 type mica tape as innermost layer insulating material, replaces interlayer wrapping until the regulation number of plies of designing requirement is guaranteed 1/2 stacked package technological requirement with TH-2 type mica tape.
The technical solution used in the present invention is: the necessary strict unidirectional wrapping of stator coil wrapping, take TH-1 type mica tape as innermost layer insulating material, and replace interlayer wrapping until the regulation number of plies of designing requirement is guaranteed 1/2 stacked package technological requirement with TH-2 type mica tape.2/3～1/2(of straight line wrapping Ying end, start-stop position hypotenuse is counted from nose), mica tape wrapping length successively increases progressively from inside to outside, forms tapering.The minimum beginning of size of taper when end wrapping is wrapped up from straight line, along successively 1/2 wrapping of taper dimensions, 1/2 mica tape width staggers between each layer.The wrapping manufacture of stator coil straight line portion and end will form the good transition with straight line, and wrapping requires the docile and obedient air gap that do not have.
This two kinds of mica tape mixing interlayers wrapping has the advantages such as good mechanical property, withstand voltage properties are good, insulating impregnating varnish good penetrability with respect to the single wrapping of mica tape of other kinds.The mechanical performance that two kinds of mica bands are used in conjunction with relatively and the like product of traditional handicraft manufacture on average improved 5%, and withstand voltage properties has on average improved 10% left and right.For attenuate fixed subcoil insulating, raising electric efficiency provide the foundation.
Accompanying drawing explanation
Fig. 1 is the wrapped mode that common electric machine stator coil is manufactured; Fig. 2 is the novel wrapped mode that Large Efficient coil of stator of motor is manufactured.
Embodiment
The wrapped method of large-sized asynchronous high efficiency motor stator coil manufacture comprises: select TH-1 type mica tape and TH-2 type mica tape 1..2. stator coil wrapping must strict unidirectional wrapping.3. take TH-1 type mica tape as innermost layer insulating material, replace interlayer wrapping until the regulation number of plies of designing requirement is guaranteed 1/2 stacked package technological requirement with TH-2 type mica tape.
In Fig. 2, take TH-1 type mica tape as innermost layer insulating material, replace interlayer wrapping until the regulation number of plies of designing requirement is guaranteed 1/2 stacked package technological requirement with TH-2 type mica tape.
During concrete enforcement, at the wrapped hands-operation of professional fixed subcoil insulating.In two band roller cartridge of fixed subcoil insulating winding machine, upper TH-1 type mica tape and TH-2 type mica tape are installed respectively.Must take TH-1 type mica tape as innermost layer insulating material, mica tape starts machinery after being attached to coil top, the stator coil mechanically speed of service is suitable, guarantee 1/2 stacked package technological requirement, 2/3～1/2(of straight line wrapping Ying end, start-stop position hypotenuse is counted from nose), mica tape wrapping length successively increases progressively from inside to outside, forms tapering.
The minimum beginning of size of taper when end wrapping is wrapped up from straight line, along successively 1/2 wrapping of taper dimensions, 1/2 mica tape width staggers between each layer.The wrapping manufacture of stator coil straight line portion and end will form the good transition with straight line, and wrapping requires the docile and obedient air gap that do not have.Through being up to the standards, can turn lower order.This method is TH-1 type mica tape and TH-2 type mica tape replaces the wrapped method of Novel stator coil insulation that interlayer is wrapped up.
