Embodiment Construction

[0008] Specific embodiments of the present invention are described in detail below.

[0009] Due to the small size of the medium-frequency motor, when winding a high-current coil, due to the need for multi-strand winding and high slot fullness, the existing winding machine is not competent for the coil winding of the medium-frequency motor. In order to use the existing winding machine to wind the high-current medium-frequency motor coil, the present invention researches and develops a new winding method of the medium-frequency motor coil.

[0010] When winding the coils of traditional excitation motors, the method of double-slot series power supply is adopted. However, in the present invention, by winding wires on the double slots of the stator in a non-serial manner, the original double slot series power supply mode is changed to double slot time-sharing power supply, and the wires wound on the double slots are connected Rectifier, the time-sharing supply of electricity is r...

Abstract

The invention relates to a winding method of an intermediate-frequency motor coil. Wires are wound on the stator of an intermediate-frequency motor via a wire winding machine so that a stator coil is formed. The winding method mainly comprises the following steps that the wires are respectively wound on the double grooves of the stator in a non-series-connection mode so that time-sharing power supply can be formed by the double grooves; the wires respectively wound on the double grooves are connected in parallel and outputted through a rectifier; and the well-wound stator coil is cut off from the middle, and the single-side outlet wire of the coil is changed into the four-side outlet wire so that users of 110V voltage can realize parallel connection and output by using a 220V winding directly without transforming a stator winding. With application of the method, programs are well set on the wire winding machine in one time and then the whole coil can be completed in one time, and double voltage of 220V and 110V can be freely selected so that the process of manual winding is reduced and scale degree is enhanced.

Description

technical field [0001] The invention relates to a method for winding a coil, in particular to a method for winding a coil of an intermediate frequency motor. Background technique [0002] The intermediate frequency motor has incomparable advantages over traditional excitation motors in terms of energy saving and consumption reduction due to its large saving of metal and other materials. However, the intermediate frequency motor is a new type of motor, and it is still relatively young compared with the excitation motor with a century of accumulation. Therefore, there is not much experience that can be used for reference on how to wind the coil of the intermediate frequency motor. [0003] One of the advantages of intermediate frequency motors compared with traditional excitation motors is the reduction in volume. The volume of intermediate frequency motors is reduced by 1 / 4 to 1 / 2 compared with excitation motors of the same power. However, with the reduction of the volume, t...
