For the kitchen food garbage disposal, the motor and cutters are crucial parts, so the paper mainly discusses them.Through analyzing mechanical, the article figures out liquid resistance and liquid pressure; we obtain resistance of trash when it be smashed. because the garbage in our country own different rigid and stickiness, so the cutter is made up by fasten-cutter, swing-cutter and rotation cutters .In this paper, electric machine has features that it star frequency and work intermittence. For it is crucial for the device, so it is important to choose a appropriate motor. Now, we decide to apply permanent magnet direct current motor, the magnetic pole of permanent magnet direct current motor is a permanent magnet material, it is excellent in simple structure: small volume, powerful output and high efficiency.In this paper, Compared to foreign machine, improve crush efficiency through alter the structure of combination cutters, then, decrease the cost .Keywords：Food； Garbage； Cutters； Permanent magnet motor PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT 1目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc28985 摘 要 PAGEREF _Toc28985 I HYPERLINK \l _Toc9820 Abstract PAGEREF _Toc9820 II HYPERLINK \l _Toc21232 目 录 PAGEREF _Toc21232 1 HYPERLINK \l _Toc16174 第1章 绪 论 PAGEREF _Toc16174 3 HYPERLINK \l _Toc25269 1.1厨房食物垃圾处理的紧迫性 PAGEREF _Toc25269 3 HYPERLINK \l _Toc17609 1.2厨房食物垃圾的特征及其危害 PAGEREF _Toc176
