Z4-180-41 DC 81kw Motor 400V 81kw

Brief Introduction

Produced by Xi'an SIMO Motor, Z4 series separately excited DC motors are premium industrial direct current motors manufactured strictly to JB/T6316 national standard and certified with CE mark, serving global industries demanding precise variable-speed transmission. The 81kw motor, model Z4-200-31, is a flagship specification of this product lineup, engineered with separate excitation structure (SEP.180 excitation mode), rated at 400V armature voltage, 224A armature current and dual adjustable speeds of 1350rpm & 2800rpm, with fixed excitation current of 7.45A for stable magnetic field control. As a mature bulk model, this motor adopts S1 continuous working system to support round-the-clock nonstop production operation without frequent downtime.

The Z4 DC motor range boasts prominent structural and performance advantages compared with conventional DC drives. First, all motors are equipped with Class F insulation graded at 155℃, which effectively restrains excessive temperature rise under long-term heavy-load running and improves overload resistance. Its IP21S enclosure protection prevents solid foreign matter and splashing water from entering internal components, extending overall service life; D.E 6314/C3 and N.D.E 6214/C3 clearance bearings minimize mechanical friction and operating noise for smooth rotation. The IM B3 foot-mounted installation layout simplifies field assembly and equipment docking, while IC06 cooling design optimizes airflow dissipation to keep steady working temperature. Weighing 525kg, the standard-spec 81kw motor balances robust mechanical rigidity and moderate footprint, easy to integrate into existing production lines. Independent excitation circuit enables seamless wide-range stepless speed regulation, greatly boosting control accuracy and energy efficiency during variable-load operation.

Z4 series DC motors enjoy extensive coverage across heavy and light industrial sectors. In metallurgical processing, they drive auxiliary rolling equipment, coil winding machines and raw material conveyor systems, relying on strong low-speed torque and anti-overload property to cope with fluctuating load conditions. For papermaking, printing and textile industries, their accurate speed control guarantees consistent product forming, lowering production reject ratio effectively. Besides, these motors are widely matched with plastic extruders, mining auxiliary lifting machinery, cement processing auxiliary equipment and hydraulic pump drive units. Under standard working conditions (ambient temperature 0~40℃, altitude ≤1000m), all Z4 motors including Z4-200-31 81kw motor maintain stable output performance without power attenuation. Every unit undergoes strict off-line testing before factory delivery, cutting later maintenance cost and becoming the preferred variable-speed power source for global industrial equipment integrators.
