Abstract

The invention relates to a motor coil winding tool, in particular to a size-adjustable motor coil winding tool and a winding method based on the tool, and solves the problems that an existing coil winding tool is complex in shape, high in machining difficulty, long in production period and incapable of being universally used for motors with different base numbers. The tool is characterized by comprising N veneer assemblies, a positioning mandrel and a fastening nut; the veneer assembly comprises a bottom plate, two square sliding blocks, two round sliding blocks and six fastening screws; a first through hole and four first strip-shaped holes are vertically formed in the bottom plate; the center of the first through hole and the axes of the four first long-strip-shaped holes in the length direction correspondingly coincide with four line segments of a diagonal intersection point of a first rectangle and two diagonals separated by the diagonal intersection point respectively; the squaresliding blocks and the circular sliding blocks are fixedly connected to the same side of the bottom plate through fastening screws; the positioning mandrel comprises a limiting section and a mountingsection; and the N veneer assemblies are sleeved on the mounting section and are fixedly connected with the positioning mandrel through fastening nuts.

Description

technical field

[0001] The invention relates to a motor coil winding tool, in particular to an adjustable size motor coil winding tool and a winding method based on the tool. Background technique

[0002] The rotor of the permanent magnet motor has no loss and has higher efficiency. The motor is small in size and light in weight. The air gap flux density is generated by the rotor magnetic steel. The power factor is high and there is no need to install a gearbox. Widely used in a variety of production machinery in various industries such as agriculture.

[0003] According to the requirements of different industrial and agricultural production machinery, permanent magnet motor drives are divided into three categories: constant speed drive, speed control drive and precision control drive. For different motor drive methods, the precision requirements for control drive are also different. Those with higher requirements for control and drive precision also have higher requiremen...
