Synchronous gearless traction machine convenient to maintain for elevator

The invention belongs to the technical field of gearless traction machines, particularly relates to a synchronous gearless traction machine convenient to maintain for an elevator. The synchronous gearless traction machine convenient to maintain for the elevator aims to solve the problems that an elevator driving system is seriously vibrated due to improper installation in a traction machine base installation mode, disassembly operation in an existing installation mode is tedious, and overhaul and maintenance are inconvenient in the prior art. The following scheme is provided. The synchronous gearless traction machine convenient to maintain for the elevator comprises a traction machine base and amounting installation base, wherein a first connecting groove is formed in one side of the traction machine base, a second connecting groove and two third connecting grooves are formed in the bottom of the traction machine base, the installation base movably abuts against the bottom of the traction machine base, two in
