Overview of Z4 Series DC Motors

The Z4 Series DC Motors are our factory's flagship products, developed with over 20 years of technical experience. Widely used as prime movers in various industries, including lifts, cableways, rolling mills, crane hoists, extruders, printing machines, and paper machines.

These motors comply with IEC72 for mounting dimensions, except the axial distance between mounting holes (dimension B). Their performance and technical requirements are in accordance with IEC34-1 or DIN57530 standards. Compact angular design ensures efficient space utilization. Laminated yokes allow operation with rectifier supplies under ripple and rapid current changes.
