摘要

馬達減速機是廣泛使用於煉油廠、生產工廠等的動力系統產品，其機型規格、系統設計匹配、應用操作及維護等，嚴重影響能源效率，低效率的機型所增加的耗用電費超過一倍，但是使用者普遍不瞭解，在選購和應用上有許多改善的空間，因此減速機之能源效率測試，實為刻不容緩的課題。
本研究建立一套制動器法的馬達減速機效率檢測機台，可測試馬達減速機之效率，試驗分別測3HP馬達搭配減速比1:20與1HP馬達搭配減速比1:60之齒輪式馬達減速機，以及以1、2、3HP馬達分別搭配減速比1:10、1:20、1:30蝸輪減速機之能源效率檢測，分別量測輸出軸扭力、輸出軸功率、功率因素、輸入軸功率、輸入轉速、輸出轉速等，進而計算其效率。
由試驗結果可知，馬達1HP減速比1:60之齒輪式馬達減速機，在負載100%時效率為80.98%，而效率最好是在120%時；馬達3HP減速比1:20之齒輪式馬達減速機，在負載100%時效率為85.00%，而效率最好是在負載為150%時，馬達2HP減速比1:10之蝸輪減速機在負載100%時效率為79.30%，較相同減速比效率提升4.86%；馬達3HP減速比1:20之蝸輪減速機，在100%負載時效率為78.14%，較相同減速比效率提升18%的效率；馬達3HP減速比1:30之蝸輪減速機，在負載100%時效率為61.66%，較相同減速比之減速機提升15.91%。

The motor speed reducer was a widespread used motor dynamic system product. The energy efficiency would be influenced by its specification, system design match, application operation and maintenance . Lower efficiency type increases consumes of the electrical power. But the user does not understand clearly. Therefore the energy efficiency test of the motor reducer is an urgent topic.
A brake method for motor speed reducer energy efficiency test was established in this study. The purposes of this study were test the efficiency of eleven speed reducer, 3HP with 20 reduce ratio and 1HP with 60 reduce ratio of gear speed reducer, and 1HP, 2HP, 3HP with 10,20,30 reduce ratio of worm speed reducer. The output shaft torque, output power, power ratio, input power, input and output speed were measured. The energy efficiency was calculated by these parameters.
The test results showed that the energy efficiency for 3HP with 20 reduce ratio are 80.98% at full load and best efficiency is at 120% load. The energy efficiency for 1HP with 60 reduce ratio are 85.00% at full load and best efficiency is at 150% load. The energy efficiency for 2HP with 10 reduce ratio are 79.30% at full load, it increased efficiency of 4.86% with same reduce ratio. The energy efficiency for 3HP with 20 reduce ratio are 78.14% at full load, it increased efficiency of 18% with same reduce ratio. The energy efficiency for 3HP with 30 reduce ratio are 61.66% at full load, it increased efficiency of 15.91% with same reduce ratio.
