Embodiment Construction

[0012] Winding process:

[0013] 1. Select the appropriate positioning piece, positioning ring and positioning commutator according to the size of the wire to assemble the double coil winding device;

[0014] 2. Introduce the wire for winding. When winding, reserve a certain length of the upper thread for spare, and carry out the first layer winding of the first coil. When the coil is wound, there are positioning devices at both ends of the coil for shaping;

[0015] 3. After the first layer of winding is finished, enter the winding of the second layer by positioning the commutator piece at one end of the coil, and then enter the winding of the third layer in turn until the required number of layers is reached, and then turn to the second winding. ;

[0016] 4. After the winding of one coil is finished, the wire is led to another coil for continuous winding through the shaping steering wheel, and the winding method is the same as that of the first coil.

[0017] 5. After the...

Abstract

A winding method of double coils of a motor is disclosed. The method relates to the motor coil and specifically relates to a winding technology field of the direct-driven-motor double coils. In the invention, firstly, a first group of coils is wound around a double layer winding frame; and then through a positioning commutation wheel, a second group of coils is wound around the double layer winding frame. In the invention, double coil winding can be achieved on the same double layer winding frame. The method is easy to be realized. Production efficiency can be effectively raised and precision of the coil winding can be raised. A resistor balance degree can be increased. A high temperature at which the coils can be damaged during a welding process can not appear so that reliability of a wind driven generator can be ensured.

Description

technical field [0001] The invention relates to motor coils, in particular to the technical field of winding double coils of direct drive motors. Background technique [0002] As a clean and renewable energy source, wind energy will have a very broad development prospect as the technology gradually matures and its operating cost will be lower than that of hydropower and thermal power in the future. With the continuous increase of the capacity of the current wind turbines, the variable speed constant frequency and variable pitch wind turbines gradually occupy a dominant position. The gearbox is a component with a high overload and premature failure rate in the current MW-level wind turbines. Foreign countries have begun to develop a direct-drive wind turbine (also known as: gearless wind turbine), which uses multi-stage The asynchronous motor is directly connected to the impeller for driving, eliminating the traditional component of the gearbox. It has many advantages such a...
