Application
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 57530 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

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.
