>> Back to Menu << Series Z4 D-C Machines Technical Data Table(1) Technical Data Table(2) Features and Uses Series Z4 d-c machines are newly developed products of our works. 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). Performance and technical requirements of the motors can be checked in accordance with IEC34-1 Standard of the International Electrotechnical Commission, 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 that when used on rectifier power supplies they can endure both current ripple and rapid current change (load change) under dynamic condition. The stator design leads to high accuracy of pole spacing and consequent good commutation. The 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 the relevant technical data, should be inserted in the armature circuit to suppress ripple current.
