摘　　要：根据设施农业环境特点,设计了电动微耕机结构形式及传动系参数,开发了温室大棚用供取电系统及单输入三输出变频调速系统,并对电动机及变频调速系统进行了试验研究,研制了一种温室大棚用电动微耕机系统。研究结果表明:在变频调速系统控制下的电动机具有低速恒转矩、高速恒功率的输出特性,能够较好地满足温室大棚作业工况需求;随着转速增大电动机输出效率增大,当转速达到1 500 r/min时,最高效率达到84.6%;当输出转速降至1 200 r/min时,电动机效率仍能够达到81.7%,具有较宽的高效调速范围;所研制电动微耕机安全性能等指标符合相关标准规定,且具有低噪声、零污染的特点;其单位小时的耕作效率约为2.29亩,略高于同功率汽油微耕机;每亩耗电量约为0.46kW.h,其经济性能远高于同功率的汽油微耕机。Based on the agricultural characteristics of the facil- ity agriculture environment, the structure of the electric micro-farm- ing machines and train parameters were designed, and the taking e- lectrical system and a single input and three outputs frequency con- trol system were developed for greenhouses, and the motors and fre- quency control systems were experimental studied. A prototype of an electric micro-farming machine was developed, and an experi- mental study was carried out. The experiment results showed that： the motor has the characteristics of low speed constant torque and high speed constant power output under the control of frequency control system, can better meet facilities agronomic conditions de- mand; as the speed increases the efficiency of the motor output in- creases, when the speed reaches 1 500 r/min, the highest efficiency of 84.6% is achieved; when the output speed is reduced to 1 200 r/min, the motor efficiency is still able to reach 81. 7%, that means the motor has a wide and efficient speed range; the safety performance of the electric micro-farming machine conforms with the provisions of the relevant standards, and the machine has the characteristics of low noise and zero pollution; the farming efficiency per hour is about 2.29 acres, slightly higher than the gasoline micro- farming machine with the same power; the power consumption is a- bout 0.46 kW · h per acre, its economic performance is much high- er than the gasoline micro-farming machine with the same power.
