The innovative Z series Large Size DC Motor is ingeniously crafted using a polygon structure that maximizes the utilization of the stator's inner space to its fullest potential. This masterfully engineered design features a magnet yoke that is meticulously laminated, making it perfectly attuned for a silicon-controlled commutate power supply. It boasts a remarkable ability to withstand pulsating currents and rapid current shifts, ensuring seamless adaptation to load changes.

The magnetic poles are crafted with precise orientation to enhance performance. All motors in this stellar system are equipped with compensate winding, ensuring outstanding reverse performance. The motor's insulation class is F, utilizing a highly dependable insulation structure paired with state-of-the-art nonmenstruum vacuum pressure impregnation, which guarantees stable insulation performance and superior heat dissipation.
