Abstract

The invention discloses a method for heating magnet glue in an iron shell of a DC motor. By providing a heating seat capable of rotation, the magnet and the iron shell of the DC motor are arranged on the rotating body of the heating seat; the annular heating coil is stretched It is strip-shaped to form a heating channel, and the two ends of the annular heating coil are bent to form a channel inlet and a channel outlet; from the channel inlet, the heating seat is sent into the heating channel, and the heating seat is moved along the heating channel. Rotate the heating seat while the seat is being turned. As a result, the magnet and the iron shell can be heated uniformly, avoiding the problem of magnetic cracking or even magnetic fragmentation caused by local overheating.

Description

technical field [0001] The invention relates to the technical field of DC motor assembly, in particular to a heating method for magnet glue in the iron shell of the DC motor. Background technique [0002] At present, the iron shell heating of DC motors on the market is generally fixed on the heating base by an iron shell, and the annular heating coil is distributed around a single iron shell. The disadvantage of this method is that due to the long high-frequency heating time, multiple high-frequency heating coils and high-frequency power supplies are required to meet the 3-4 second rhythm of a single machine, which will be very expensive. In addition, due to the fixed heating of the iron shell, it is easy to cause excessive heating locally, which in turn leads to the problem of magnetic cracking or even magnetic fragmentation. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the prior art, the main purpose of the present invention is to provide a meth...
