621-1160RHONEYWELL霍尼韦尔普通异步电动机都是按恒频恒压设计的，不可能完全适应变频调速的要求。一般情况下，不建议采用变频器带普通的三相异步电机进行调速控制。一般专用的变频电机，会有专门的散冷装置，即外接散热风扇，再就是从制作工艺方面来说，比较严格，制作材料绝缘等级较高，比一般电机耐温升，而且变频频率的范围较广从5HZ-------100HZ，甚至可以高达几百HZ的频率。普通电机一般没有专门的散冷风扇，常见的是带有风扇翅，再就是能够变频运行的范围较窄，一般不高于基频，最低频率在30HZ左右，常见的在基频附近变频。以下为变频器对电机的影响——1、电动机的效率和温升的问题不论那种形式的变频器，在运行中均产生不同程度的谐波电压和电流，使电动机在非正弦电压、电流下运行。拒资料介绍，以目前普遍使用的正弦波PWM型变频器为例，其低次谐波基本为零，剩下的比载波频率大一倍左右的高次谐波分量为：2u+1（u为调制比）。"高次谐波会引起电动机定子铜耗、转子铜（铝）耗、铁耗及附加损耗的增加，最为显著的是转子铜（铝）耗。因为异步电动机是以接近于基波频率所对应的同步转速旋转的，因此，高次谐波电压以较大的转差切割转子导条后，便会产生很大的转子损耗。除此之外，还需考虑因集肤效应所产生的附加铜耗。这些损耗都会使电动机额外发热，效率降低，输出功率减小，如将普通三相异步电动机运行于变频器输出的非正弦电源条件下，其温升一般要增加10%--20%。2、电动机绝缘强度问题目前中小型变频器，不少是采用PWM的控制方式。他的载波频率约为几千到十几千赫，这就使得电动机定子绕组要承受很高的电压上升率，相当于对电动机施加陡度很大的冲击电压，使电动机的匝间绝缘承受较为严酷的考验。另外，由PWM变频器产生的矩形斩波冲击电压叠加在电动机运行电压上，会对电动机对地绝缘构成威胁，对地绝缘在高压的反复冲击下会加速老化。176B60013HAB2241-13HAB5845-13HAB5956-13HAB6372-13HAB7215-13HAB8101-103HAB8101-33HAB8101-83HAC1462-13HNE00313-1MC07A005-5A3-4-00MC07A008-5A3-4-00MCO7B0011-5A3-4-006ES5482-8MA131756-A101756-A171756-A41756-A71756-CN2R1756-EN2T1756-IB161756-IF161756-IF16I1756-IM16I1756-IR6I1756-L631756-N21756-OA161756-OB16E1756-OF81756-PA75"1756-RM"1756-TBCH1756-TBNH1786-BNCJ1786-RPA1786-RPFRXL1786-TPS1786-XTDOU2.5DV505-400SABWL12G-V530DV505-400SAB64KBYTE700-951-OKF00330980-50-00A06B-6093-H152ASBSV8/LED-5G4ODC5OPTO22A06B-0243-B1001756-A101756-A171756-A41756-A71756-CN2R1756-EN2T1756-IB161756-IF161756-IF16I1756-IM16I1756-IR6I1756-L631756-N21756-OA161756-OB16E1756-OF81756-PA751756-RM1756-TBCH1756-TBNH1786-BNCJ1786-RPA1786-RPFRXL1786-TPS1786-XT2098-DSD-010X2098-DSD-020X6FC5410-0AY01-0AA1A06B-6134-H3022711-K10C16IC200ACC313IC200ALG230IC200CHS022IC200CPU001IC200MDL631IC200MDL750IC200PWR101IC200TBM002IC647MPS101IC690PWR024CLM01.3-X-0-4-FWVS-656MR56SE9531-7DK40E0451-521-038IC695CPU3104351BABC-PDPAB7000-CGZAH821107P0158140ACI04000140NOE77100140XTS00200140ACI03000140ACO13000140ARI03010140CPS11420140CPU65150140CPU67160140CRA93200140CRP93200140DDI35300140DDO35300140NOE77101140XBP00600140XBP01000140XBP01600140XTS002003EH73031BBAF6FC5210-0DA20-2AA1DSAO120DSAO120ADSDP170TU810V1IC647TRT000IC647TRT999CAN-CBM-DPSE-B5.700.020-00.0002711-K10C152711-NM2322711-NMCC1771-CT1771-OWNA1784-PCIC/B1784－PKTXMA0185100PC832-001-TDV505-400SAB48PT2-9003E110ED5101336F-B100-AE-ENCP5611PCI-1602BHC-KFS73MR-J2S-70AA03B-0819-C512TVD1.3-08-03DSAI130DSAI145/146DSDI120ADSTA131DSTA145DSTD150ALE4-116-DD1FR-D740-3.7K-CHTFR-F740-55K-CHT3051CD2A02A1ABH2(0-40KPA)3051CD2A02A1ABH2(0-10KPA)3051CG2A02A1AH2B1(0-40KPA)3051GP1A2B21AB4(0-100KPA)3051GP3A2B21AB4(0-0.6MPA)3051GP3A2B21AB4(0-1.6MPA)3051GP3A2B21AB4(0-1MPA)3051GP3A2B21AB4(0-4MPA)6EW1811-8AAHMS01.1N-W0020-A-07-NNNNHMS01.1N-W0036-A-07-NNNN140CPU434129907-1676ES7315-2AG10-0AB01756-DNB/D140CPU43412A140DDI84100140DRA84000G3SM50/100-T5X00119G01CIMR-HB4A05156ES7315-2AG10-0AB06ES7321-1FH00-0AA06ES7953-8LG20-0AA0C200H-IA222CIMR-HB4A0180DCS800-S02-0260-05+K454+控制盘DCS800-S02-0450-05+K454+控制盘HLE45-600H-3F.ACHLE45-600L-3F.AC1756-CNB1756-CNB/DLKA5BVT3006-S35/R1MPG-4RFIC693MDL753A20B-2000-0670-04D140CRA93200140CRP932001746-IB161746-OB161746-P21747-L5321756-CNBR/EPM856PM856K01LD4-LC130DSAI130DSAO120DSAO120ADSDI110ADSDO115DSDP170TB807TU810V11746-HSRVDSDP1506EW1861-2AE1203-GK1SRM50-HWA0-K011336-QOUT-SP25A1336-SN-SP16A1756-CNB/D1756-ENBT/A1794-OE12IC697CGR935A06B-6079-H1061769-OB32AK-BX556M6SE6430-2UD42-5GBODCS40-25194R-NJ100P36GK1105-2AE003401PC32000FCIMR-MR5N27P5IC3645OSC5E90811405060140CPU53414AIC3645OSC5E9194R-NJ100P3DCS-401-0405REV.A.1405AJ120-172J120-190J120-485J120-S147B1756-CNBR1756-ENBT1756-L631756-RMDC2500-CE-0A00-200-00000-00-0XBTF011310PWS6600S-S2098-DSD-010A16B-2203-0073/02AA16B-2203-0073/02A140ACI03000140ARI03010140CPS12420140CPU65160140CRA93200140DDI35310140DDO35320140XBP0100140XCP5100140XTS0020051403776-100H117AL112F16632BA16B-1212-0950DS41-30DS4600A-22201336F-B025-AE-EN1336-WB009A02B-0319-B502A249SS-120-A-G6RA7085-6DS22-0-ZZ=S00+K00INNIS21INNPM126ES7-151-1AA04-0AB01398-DDM-019IC695CPU315IC695PBM300IC695PSA0400-51378-191756-CNB1756-DNB/D1756-PA756ES7317-2EK13-0AB03503E351136253700A3805E8312A06B-0034-B0771C31194G011C31197G01TC-IDD321140ACI03000140ACO13000140ARI03010140CPS11420140CPU65150140CPU67160140CRA93200140CRP93200140DDI35300140DDO35300140NOE77101140XBP00600140XBP01000140XBP01600140XTS00200990XCP98000MA0185100MA0186100MA0329001PTQ-PDPMV1TSXBATM02TSXMRPC003MTSXMRPC007M1769-IF16C1769-OF8C531X111PSHASG3AK-BX511M2QA225M8ACS550-01-015A-4ACS550-01-08A8-4PSS30/52-500LPSS37/64-500LPST50-600-701756-DNB/A1756-ETHERNET1336-BDB-SP30D1336F-B100-AE-EN1336-QOUT-SP13AJWS600-246GK7343-1EX21-OXEO6DR5010-0NG00-0AA01756-A10/A1756-DH/RIO1756-IF161756-OF81756-PA72/B2711-B6C103805EA06B-6079-H101A06B-6079-H104A06B-6079-H203A06B-6080-H304RS2A03A0ALOWOOIMDSO14IMFEC12YB560101-EL5100MIC200PWR102FDSO14FEC12C40H-C3DR-DE140ACI04000140ARI030101756-IF16/A1792D-8BVT8D1792D-8BVTOD1794-OA8IQAE3075.010VXF53.40-166AV6643-0CD01-1AX12CN3000TSX07301028P0940AXP0940CUP0940DHP0940HQDSO14FCM10EFEC12505-CODACCESS4000CIMR-JB4A00116ES7416-1XJ02-0AB06GK1541-2BA006ES7158-0AD01-0XA06ES7317-
