Motor linear motor coils can be divided into formed linear motor coils and loose linear motor coils. Formed linear motor coils refer to coils of a fixed shape that are pressed and formed by molding equipment. The shape, size, pitch and other inherent characteristics of such coils after pressing cannot be Change. The loose-wound motor linear motor coil refers to the coil wound by the winding die (usually with enameled wire), and the shape and size of the wire can be greatly adjusted according to the actual situation on site.
Generally speaking, the formed linear motor coil is used for the winding of large and medium-sized motors, and the compressive strength of the insulation layer of the formed linear motor coil is better than that of the loosely wound linear motor coil, which is due to the uniqueness of the selection of the magnet wire.
Under normal circumstances, most of the motor windings with a center height of 315 or below use loose-winding linear motor coils. Due to the limitation of the diameter and length of the motor core, the internal space of the motor is relatively narrow. The end is shaped, but the slot filling rate of the motor is relatively low, so the motor loss is large and the output power is low.
On the premise that each transmission line has an insulating layer, the forming motor linear motor coil will have one or more additional insulating layers after the wire is formed, and the specifications are not easy to change after forming by the forming machine.
Loose-wound coils are more suitable for mass production, and forming motor linear motor coils will be damaged by forming machinery and equipment, and the output will be smaller.
On the premise that each wire is insulated, one or more layers of insulation will be added after the coil of the motor linear motor is wound and formed. .From the point of view of batch, the loose wound motor linear motor coil is more suitable for mass production, the formed coil is affected by the forming machine, and the daily output will be smaller.
Literally and practically, a coil that is manually wound with an enameled round copper wire through a winding die is a loose-wound coil, and a coil whose length, span, and elevation are fixed (or basically fixed) with a forming die is a forming coil. Some forming coils Due to the small cross-sectional area of the wire, it can also be broken, but the span and elevation after breaking will not meet the requirements of the drawing. The purpose of winding the coil is to limit the circumference of the coil, and the pitch and elevation are adjusted according to the drawing during the burying process.
