Big DC Motors in Textile Industry

big dc motors in textile industry**Description:Z series middle-size dc motors (frame size 450mm-710mm), adopt the latest technology, are our new products.  The performances, outline mounting dimensions and main technical parameters are complied with GB standard and international IEC standard. The dimension and tolerance of motor parts comform with ISO standard.Z series DC motors are widely used on in metallurgical industry, Hardware Industry,   papermaking industry, dyeing industry, construction industry, plastic extrusion machinery, etc.Typically used as prime mover in rolling mill, metal-cutting machine, cenment mill, etc.By adopting advanced design and polygon laminated structure stators, Z series motors are fully use the space, feature with small size, light weight, and good performance.The magnet yoke, pole and armature core are made of overlied good quality cold rolled silicon steel plate. Z series dc motors have perfect permeability performance.All the stators of Z series motor need to do varnished processing. After that, the windings have good moisture resistance, mechanical strength and excellent insulation and heat conduction performance. The insulation class reach class H.**Performance:1. Working duty: S1, continuous.2. Standard armature voltage: 220v, 330v, 440v, 550v, 660v, 750v. Any voltage between 200v~790v can be customized.3. Excitation type is separate excitaion. The basic excitation voltage is 220v. Other voltages can be designed according to clients requirement. Z4 series dc motor allow force excitation. When force excitation, excitation current can temporarily above rated current. After excitation current get stable, it can not above rated current.4. Z series dc motors have short-time overload capacity.5. The noise of Z series dc motor comply with GB/T10069 and IEC34-9.**Working conditions:1. Cooling method:  IC06, IC17, IC37, IC86W2. Protection: IP23, IP443. Mounting: IMB34. Ambient temperature: -15 ~ +40 Celsius degree5. Altitude: within 1000m6. Voltage: Direct current, according to srmature voltage**Technical parameter.For example: Z450-3A, excitation voltage 220vRated powerRated speed (r/min)under rated voltageMax.speedArmature urrentExcitation powerEfficiencyRunning inertiakw750v660v550v440vr/minAkw%kg2·m          390460   1500570 91.247.9340 400  12005706.390.3275  325 1000563 88.8215   255900566 86.3470550   1600678 92.3410 480  1600678 91.6340  395 1200685 90.2265   31010006836.488.2595675   1500850 93.350.2520 590  1500850 92.7430  485 1500853 96.6335   3801200845 90750840   15001060 94.349655 735  150010576.593.9545  605 15001064 93.1430   48015001063 91.8700 830  15001129 93.950.2580  685 15001132 93.1460   540150011366.491.9700  820 15001356 93.852.5555   65015001358 92.8690   80015001674 93.6big dc motors in textile industry**Our service:1.
