Power motor performance in largely decided to the EPS system performance, so EPS system to motor performance requirements of the high. Compared to normal motor, electric power steering system with the motor should have the following characteristics. First of all because most vehicle power supply for 12 V dc, therefore, ask dc motor power supply electricity down and have big rated current of the rated power; and Secondly, the volume as low as possible, inertia, wide range of speed regulation of small, control characteristic, smooth operation, and low torque fluctuation little, low speed. High speed, big gear ratio will increase of mechanical system, the influence of system dynamic performance inertia; In turn blocking when can also provide power torque. For large vehicles, or even should be able to provide the opposite direction of power and rotational torque. 附錄B 助力電機為EPS提供動力，是EPS系統(tǒng)的動力源，它根據(jù)ECU單元的指令，輸出適宜的助力轉(zhuǎn)矩。助力電機的性能在很大程度上便決定了整個EPS系統(tǒng)的性能，因此EPS系統(tǒng)對電動機的性能要求很高。相對普通電動機，電動助力轉(zhuǎn)向系統(tǒng)用電機應該具有以下特點。首先由于絕大多數(shù)車載電源為12V直流，因此要求直流電機供電電壓低，并且具有大的額定電流和額定功率;其次，體積盡量小，轉(zhuǎn)動慣量小，寬廣的調(diào)速范圍，控制特性好，低速運行平穩(wěn)，力矩波動小，轉(zhuǎn)速低。高轉(zhuǎn)速下，大的齒輪傳動比將會增加系統(tǒng)的機械慣量，影響系統(tǒng)動態(tài)性能;在堵轉(zhuǎn)時也能提供助力轉(zhuǎn)矩。對于大型車輛，甚至應該能夠提供與轉(zhuǎn)動方向相反的助力轉(zhuǎn)矩。
