Description

technical field [0001] The invention relates to the technical field of motor load simulation, in particular to a ship propeller load simulation device. Background technique [0002] The technology in the field of ship electric propulsion continues to develop, but during the actual navigation of the ship, the installation position of the propeller, the wake and the water absorption of the propeller will all affect the operation of the motor. The actual working condition of the propulsion motor is more complicated than that of ordinary motors. Safety, reliability, and control performance testing of ship electric propulsion motors have become a key issue. At the same time, the results of ship propulsion motors under normal test conditions cannot be used as a basis for evaluating the control performance of ship propulsion motors. Therefore, we need to simulate Propeller load characteristics, tested on propulsion motors. [0003] In engineering, when carrying out operation tests...
