description The invention discloses a motor broken shaft reconnection technology. The motor broken shaft reconnection technology comprises steps 1, choosing a reconnection point and choosing a blocking root part of the motor bearing as a reconnection point between a shaft extension portion and an original motor rotor shaft end, 2 adopting a hot charging interference fit on a portion where the shaft extension portion is connected to the shaft end of the original motor rotor shaft end, 3, adopting a heating furnace to continuously heat the shaft extension part to 190 degree to 210 degree for 30-40 minutes and sleeving the shaft extension portion into the original motor rotor shaft end in a hot charging manner, 4, performing surfacing on a crevasse part of a seam after the shaft extension portion to be hot charged is cooled down, and 5, placing the rotor on a lathe after the welding portion of the shaft extension portion is cooled down and processing the portion of the connected shaft into an original shaft size which is or
