3 Series DZF D-C Machines Features and Uses Series DZF D-C machines are new developed products of our factory. The products are found wide use for prime mover in various machinery, such as mill auxiliary in metallurgical industry, metal cutting machine-tool, paper-making, print, textile, printing and dyeing, cement-making, plastic extruding machine etc. Outline mounting dimensions of the motors comply with IEC 72 Standard, except for the axial distance between the mounting holes(dimension B). Performances and technical require-ments of the motors can be checked in accordance with IEC 34-1 Standard of the international Electrotechnical Commis-sion,or DIN Norm of the Deutsche Industrie-Norm. The angular shape of the machine makes good use of space.the motors have laminated yokes, which means than when used on rectifier power supplies they can endure both current ripple and rapid current changes(load change) urder dynamic condition. The stator design leads to high accuracy of pole spacing and consequent good communicaticn. Motors are class F insulated. with reliable insulating construction and impregnating process, ensuring stable dielectric performance and excellent heat dissipation. The motors possess the features of small size, good performance, light weight, large output, high efficiency and reliability, being able to match the current international advanced level. The motors can be lastingly operated from fully controlled three phase bridge without a smoothing reactor. Motors for 160V may be operated on single phase bridge thyristor. In that case,a smoothing reactor, whose inductance is specified in Item Defination Example: DZF Code for endsheild * Code for armature core length* * Center height (mm) Code for series* * * 1 * The digit 1,2 for short, and long endshield. ** As regards frame size DZF-112, the first digit means No. of poles, the second digit for core length. *** The letter Z for d-c machine, the gigit F for ordinal number of the fourth series design.

4 Electrical Performance 1. Data listed in the technical data sheet should be employed under the following conditions; a. Altitude above sea level maximal 1,000m; b. Cooling air temperature maximal 40 ; c. Ambient conditions for motors should be free from acidic, alkali fumes or other aggressive gases which corrode insulation; d. Duty: Continuous(S1); e. Armature and field circuit for motors may be either operated on staticthyristor controlled supplies, or from d-c generator; f. Performsnces of motors all comply with State Standard GB/T755<<Fundamental technical rules for electrical machines>>. 2. Nominal rated voltage: 160V or 440V, Values for 220V or 400V or other voltage may be derived on request. 3. Rated speed: and 200r/min. lotal nine grades. Decrease armature voltage to make speed regulating under constant torque, lowering down field voltage to make speed regulating at constant output. Speed regulating range: see technical data. The given multiple of load to rated load of different speed regulating range: see technical data. The given multiple of load to rated load of different speed range see Appendix 1. The torque can be remained consta by reducing speed via armature voltage weakening below ratsd value. It is stipulated that armature speed range down to maximal 20r/min at constant torque and stable running. 4. Nominal field voltage: 180V. Other excitation voltage are also acceptable on request. Forced excitation is allowed with the voltage of less than 500V. When a motor is normally runnning, its excitaion current must not be higher than the rated excitation current. To assure the reliability of insulation of excitation system, the motor must be protected against self-induced voltages by a release resistor connected in parallel with the field winding when the wxcitation circuit of the motor is interrupted. At rated field voltage the value of shunt resistor is about seven times field winding resistance(cold). While the field voltage is higher than nominal voltage, the value of shunt resistance may be lower than seven times field resistance, otherwise higher than seven times. 5. Four frame size compensating windings are provided. For frame size Z4-250 and DZF-280 the,otors are feasible with a compensating winding too. 6. A marked earthing terminal is provided for the motors. 7. The efficiencies listed in the data sheet are for rated output, voltage and speed, and include excitation losses, excluding separate ventilating fans. 2

AVF Series Motor can match various kinds of SPWM converter plant both at home and abroad. In comparison with other speed regulating systems, it features high efficiency of energy saving, wide range of speed regulating ratio and strong adaptability of speed regulating. Besides. AVF Series Motor has low vibration and low noise. Its power grades and the height of the centerline of the frame are in conformity with IEC international standards. Its corresponding systems are highly compatible with those of A2 Series three-phase Asynchronous Motor. The two systems can be interchangeable and compatible with each other. It is so far one of the most advanced systems in the world. AVF Series Motor is equipped with independent cooling fan that assures the good cooling effects at different speeds. AVF Series Motor is now widely used in the transmission shaft of numerical control machine. Textile. Metallurgy and so on. When used for constant torque speed regulating or for diving the exhaust fan, pumps that have the decrease torque, the good output of the speed regulating system can perfectly match its mechanical characters with load and conduce to energy saving and auto-control. It is an ideal equipment for stepless speed regulating.
