Abstract
In order to improve the actual operation efficiency of overhead
passenger equipment in coal mines, a direct-drive outer-rotor
permanent magnet synchronous motor (DDO-PMSM) is designed
to replace the traditional asynchronous motor acceleration and
deceleration traction machine. Through analytical calculation and
computer simulation, the pole-slot matching of the motor and the
magnetic pole size of the permanent magnet (PM) are optimised.
Then, the DDO-PMSM is modelled and simulated by the ANSOFT
software. The rationality of the DDO-PMSM design is verified by
the no-load state and load state of the motor. Finally, the simulation
data of the PM synchronous motor is compared with the actual
running test data of the traditional mode. Comparing the results,
the rationality and practicability of the direct-drive scheme design
are verified. The design basis and reference are provided for further
optimisation design of direct-drive synchronous PM traction machine
in the same field.
