Description

[ background of the invention ]
The existing 12-48V low-voltage direct-current three-phase motor is formed by winding a double-layer fractional-slot concentrated winding on a single-needle winding machine, the number of slots and the width of a slot opening of a stator core of the 10-pole motor are respectively 12 slots and 2.8mm, enameled wires with the wire diameter of 1.41mm are adopted for serial winding, and the number of turns is 5.
Referring to fig. 4 and 5, the specific winding and wiring steps are as follows:
winding the stator core on the 1 st tooth, the 2 nd tooth, the 7 th tooth and the 8 th tooth in turn in a counterclockwise, clockwise and counterclockwise manner, and winding four coils Q '1, Q' 2, Q '7 and Q' 8 which are connected in series so as to complete the winding operation of the U-phase winding; winding the stator core on the 9 th tooth, the 10 th tooth, the 3 rd tooth and the 4 th tooth in turn in a counterclockwise, clockwise and counterclockwise manner, and winding four coils Q '9, Q' 10, Q '3 and Q' 4 which are connected in series so as to complete the winding operation of the V-phase winding; and winding the stator core on the 5 th tooth, the 6 th tooth, the 11 th tooth and the 12 th tooth in turn in a counterclockwise, clockwise and counterclockwise manner, and connecting the four wound coils Q '5, Q' 6, Q '11 and Q' 12 in series to finish the winding operation of the W-phase winding. In fig. 4, "-" denotes a counterclockwise winding and "+" denotes a clockwise winding.
The winding is found to have the following technical defects in production practice:
each phase winding has four coils and adopts the enameled wire series connection coiling of 1.41mm of line footpath, because the line footpath is thick leads to stator core's notch broad, consequently produces great cogging torque and great magnetic leakage coefficient to make the motor vibration big, the noise is high and efficient.
Aiming at the defects, the width of the notch is reduced to the interval of 2.0-2.5 mm from 2.8mm, and the situation that the enameled wire with the wire diameter cannot be produced can occur during winding, because the width of the needle nozzle of the winding machine is larger than the width of the notch due to the fact that the wire diameter is too thick, the needle nozzle cannot enter the notch so as to send the enameled wire into the groove.
