Abstract:  High-quality dynamic load simulator is an important equipment in electric drive experiment. Electric load simulation system is the new direction in the load simulation technology development filed. So researching the design and implementation of electric drive typical load simulation system has very important value. Several types of loads in actual operation are analyzed in this paper, such as constant torque load, constant power load and fan pump load, which are loading as simulation element with magnetic powder brake. Through the experiments, the characteristics of constant torque load, constant power load and fan pump load are realized.

Key words: constant torque load, constant power load, fan and pump load
