Electric Motor DC Motor (Z4 Series)

Z4 series DC motors which are newly developed, are leading products of our factory. The products are widely used as drive source of various machinery in many industry, such as metallurgy, metal cutting in machine-tool, paper-making, 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 are checked in accordance with IEC34-1 Standard of the International Electrotechnical Commission, or DIN 57530 Norm of the Deutsche Industries-Norm.

The angular shape of the machine makes good use of space. The motors have laminated yokes, which means that they are applicable to rectifier power supplies and 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 structure 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 use all controllable triphase bridge commutate power and work well without a smoothing reactor. Motors rated 160V may be operated on single-phase bridge power. 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. Its inductance is displayed as the table of technology below.
