Embodiment Construction

[0009] The wrapping methods for manufacturing stator coils of large-scale asynchronous high-efficiency motors include: 1. Choose TH-1 mica tape and TH-2 mica tape. 2. Stator coil wrapping must be strictly unidirectional. 3. Use TH-1 type mica tape as the innermost insulating material, and alternate layers with TH-2 type mica tape to wrap up to the specified number of layers required by the design to ensure 1 / 2 of the lapping process requirements.

[0010] exist figure 2 Among them, the TH-1 type mica tape is used as the innermost insulating material, and the TH-2 type mica tape is alternately wrapped with alternate layers until the specified number of layers required by the design to ensure 1 / 2 of the lapping process requirements.

[0011] During specific implementation, it is operated on a professional stator coil insulation wrapping machine. Install TH-1 type mica tape and TH-2 type mica tape on the two taping roller chucks of the stator coil insulation winding machine...

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 [0001] The invention relates to a method for manufacturing a stator coil of a motor, in particular to an insulation wrapping method for manufacturing a stator coil of a large-scale high-efficiency motor. Background technique [0002] The winding method of the main insulation of the traditional motor stator coil is a single material wrapping (such as figure 1 As shown), this wrapping method is prone to disadvantages such as low short-term withstand voltage, poor permeability of insulating impregnating varnish, low mechanical strength, and poor electrical aging. And the new motor stator coil main insulation winding method (such as figure 2 As shown), it has the advantages of good mechanical properties, excellent voltage resistance, and good permeability of insulating impregnated varnish. Contents of the invention [0003] The purpose of the invention is to provide a winding method for the manufacture of a large-scale high-efficiency motor stator coil to ov...
