BentlyNevada3300-03-03-00对于变频器，如果输出频率降低，电机转速将跟随频率同样降低。这时会发生制动过程由制动产生的功率，将返回到变频器侧。这些功率可以用电阻发热消耗。用于提升类负载,下降时能量(势能)，要返回到变频器(或电源)侧,进行制动。这种操作方法，称作“再生制动”而该方法，可应用于变频器制动。1、怎样提高制动能力?为了用散热来消耗再生功率，需要在变频器侧，装置制动电阻。为了改善制动能力，不能期望靠增加，变频器的容量来解决问题。请选用“制动电阻”制动单元”或“功率再生变换器”等选件来改善变频器的制动容量。2、当电机的旋转速度改变时，其输出转矩会怎样?变频器驱动时的起动，转矩和***大转矩，要小于直接用工频电源，驱动时的起动转矩和***大转矩。经常听到下面的说法：电机在工频电源供电时，电机的起动和加速冲击很大，而当使用变频器供电时，这些冲击就要弱一些”如果用大的电压和频率起动电机，例如使用工频电网直接供电，就会发生一个大的起动冲击(大的起动电流而当使用变频器时，变频器的输出电压和频率，是逐渐加到电机上的所以电机产生的转矩要小于，工频电网供电的转矩值。所以变频器驱动的电机起动电流要小些。FRE-201A-1ZC98043-A1601-L140ARI03010140ATI030006DD1681-0CA26DS1412-8RR6DS1717-8RR6DS1723-8BBIPM-P0904HA1746-A101746-A71756-A101771-A4B2711-NM14SW925AE1756-OF8SST-PFB-SLC1746-IA16T1F-08AD-1NR-TH081746-NI16I1746-NO8IZW-102PM6ES7315-2AF03-0AB0MDV60A0110-5A3-4-00IC670ALG3101746-IM161746-OW161747-L532IC693CMM3211C31227G011B30035H011C31164G021C31224G01A03B-0808-C0201249AFBM09FBM41P0972AJPROVIT52003HNE00314-11C31194G011C31197G01140XBP01000140ACI03000PCI-61151746-N33HAB8101-146TF-5C1747-SDN3UF5011-3BB10-16ES7416-3XL04-0AB0IC693MDL645EIC693MDL940HEVR1161756-OX8I1756-A101756-A131756-A71756-CNB1756-CP31756-DNB1756-ENBT1756-IB16I1756-N21756-TBCH6ES7470-0AA00-0AA0UDX5107-G2-2UDX5114-G4-2M063-LE-507E1756-CNBR/E1756-IF161756-OF8140DAI74000140DAO84210MPL-A320H-HJ22AARCA-S-SA5RCA-S-SSIC693CMM3211747-ASB1747-L5421747-SN140DRA84000140ACI04000140ACO13000140CPS11420140CRA93200140DAI75300IC695PSD140B140CPU11302IS215UCVEM06AXFL521BIC693CMM321-JJD***CDIGITALCONTROLLERETC902-NSCP-L850-400-G11606-XL240EIBRC-6032R1746-IA16HCMC03MC-OB26540168802140CPS11420140CPU65150140CRA93200140CRP93200140ACI03000IC697CMM7421756-ENBT140XBE10000140ARI03010140CPS21400140XTS00200140XBP00600140XCA71703140XCP510001756-L61PC-A984-1451203-CN1MVME162-212MVME162PA-252SE2711-T10C101746-IB161746-NO4V1746-NT41746-OB161746-P31746SC-NT81747-L5511747-SDN/BIC693BEM331IC693CPU364IC693PWR331KPS-60/20-ESCKSD1-08KSD1-32KSD1-48SST-PFB-SLC1746-OB16E1747-L542TSX3708001SST-PFB-SLCIC693MDL655140CRP93200140XBP01000CIMR-E7U47P51756-ENBT140ARI03010140ATI03000HE693THM166E30004380A140CRP93200140CPU43412A1C31224G01/1C31227G01PCI-6013IC697MDL350RFT9739D4140XBE10000SST-PFB-CLXMDX-052EVS9325-EP1203-CN11746-NO4VC628-810021746-NI8IC697CMM7421746-IB161746-N04V1746-NI41746-OW166DR1900-56DR2100-5HE693PBM101ELS6804-I400A1756-OF41785-V40LECPNC3-0PNC3E***60-01140DAI55300140CPS21400505-4332505-6108B505-6660545-1105IPM2-P0904HAP0903ZEP0971WV-DNBTIC697CMM742SDCS-CON-1XBTP0210101756-PA75RMK9906N.821756-M221747-L542DSQC6393HAC025097-001/08运费140DD035300AD202HGP0912ZVP0914XBP0914YM(FCM10E)P0914ZXP0916NAP0926JMAP0973CA(FEM100)***ARTSWITCH2200/2H258-17REWS600-241756-L61A-404LP3HAC16831-11746-NI46SE6411-6BD22-2CA1C500-PS222EJAMSC-B2743V6SE3214-0DA401756-EWEB35AE92GJR5137200R0002140CPS21400UDX51285X00105G071746-OB16E140ACI04000140CPS21400140CPU65150140DDI35300140DDO35300140DDO84300140NOE77101140XBP01000140XTS00200140ACI03000140ERT85410ZMVME162-020AMVME224A-3FCP2701746-P4140***O020001336F-BRF75-AE-EN5.5KW1756-BA2)
