ZDB-71K-WF2 Two Pole DC Machine 30kw 220V

Brief Introduction

Xi'an SIMO Motor's ZDB-71K-WF2 two pole dc machine stands out as a high-performance industrial direct current motor tailored for heavy-duty variable-speed industrial transmission, bringing stable, controllable power output to mechanical processing, metallurgical equipment and general industrial automation. As a mature two pole dc machine developed by SIMO, this model runs at a rated speed of 3000 rpm, with adjustable speed coverage from 0 rpm to 1000 rpm. Its rated voltage is 220V and rated power hits 30kW, paired with excitation voltage 155V to guarantee steady magnetic field operation. Certified with CE compliance, the motor meets international electrical safety standards, capable of reliable work amid ambient temperatures ranging from -40℃ to 40℃, fitting cold workshops and regular indoor production environments alike. It adopts premium SKF 6310/C3 bearings to cut rotational friction, lowering vibration and extending overall service life.

Built with rigorous industrial-grade craftsmanship, this two pole dc machine controls operational stability throughout long-duration running. Its insulation configuration and WF2 protection grade defend against dampness and mild corrosive air, preventing internal coil aging caused by harsh site conditions. The excitation circuit is precisely calibrated to eliminate magnetic flux fluctuation during speed adjustment, so torque stays consistent across the full speed range. The motor's mechanical structure undergoes strict dynamic balance testing; even under frequent start-stop and variable-load conditions, shaft rotation stays smooth without abnormal shaking. The brand sets clear lubrication maintenance rules for users, specifying universal lithium grease as bearing lubricant. Operators need to conduct full bearing inspection once the motor runs more than one year, injecting grease to fill one-half to two-thirds of the bearing chamber to avoid grease hardening, abrasion and component damage. Such standardized maintenance greatly reduces unexpected downtime and keeps long-term operating costs manageable for factories.

Backed by Xi'an SIMO Motor's mature manufacturing system, this two pole dc machine achieves precise parameter control and traceable quality management. Each unit bears exclusive serial numbers and factory inspection records, with production date traceable for after-sales maintenance and component matching. The overall design balances power efficiency and operational convenience. The wide speed regulation range allows flexible matching with fans, pumps, processing machine tools and other equipment with varying speed demands. Thanks to robust bearing assembly, optimized magnetic circuit layout and complete protective design, the motor resists temperature rise and mechanical fatigue during round-the-clock operation. Whether deployed in fixed industrial workshops or sites with temperature volatility, this SIMO two pole dc machine delivers dependable power support, integrating stable performance, convenient maintenance and international certification advantages to become a trusted drive option for global industrial customers pursuing controllable DC power.
