The invention relates to an energy-saving and efficient permanent-
magnet synchronous
elevator traction
machine testing platform which comprises an upper computer and a testing device serving as a lower computer and used for testing technical parameters of a traction
machine under different working conditions. The upper computer is a device for obtaining and
processing information detected by the testing device, the testing device comprises a driving device using industrial three-phase
electricity, a
machine to be tested, a torque rotation speed
measuring instrument and an active machine, the machine to be tested, the torque rotation speed
measuring instrument and the active machine are sequentially arranged on the base, the driving device is connected to the active machine and the machineto be tested so as to drive the active machine and the machine to be tested, the measurement end of the torque rotation speed
measuring instrument is connected with the active machine and the machineto be tested through connecting parts, and the upper computer is connected with the machine to be tested, the torque rotation speed measuring instrument and a driving part. The energy-saving and efficient permanent-
magnet synchronous
elevator traction machine testing platform saves energy, is friendly to the environment, achieves power recycling and can achieve automatic acquisition, display, analysis, storage, replay, output and printing functions of testing data, the ground performance testing efficiency of the permanent-
magnet synchronous
elevator traction machine is improved, and the working efficiency is improved.
