ZDB-72 22kw Vertical DC Motor 220V

Brief Introduction

This vertical dc motor, officially designated model ZDB-72, is a premium shunt-excited direct current motor professionally fabricated by Xi'an SIMO Motor Co., Ltd., validated with CE certification to satisfy international electrical safety and industrial mechanical standards. Rooted in mature DC motor development technology, this vertical dc motor is tailored for industrial scenarios demanding precise variable speed control and sustained high-torque output, extensively compatible with metallurgical rolling equipment, heavy-duty lifting machinery, printing presses, papermaking transmission systems and customized automated production lines. The benchmark ZDB-22TE variant of the ZDB-72 lineup features core rated parameters: 22 kW power output, 220 V rated voltage, 113.4 A rated armature current and a constant rated rotational speed of 1500 rpm. It adopts classic shunt excitation architecture, which decouples excitation control and armature operation to deliver smooth, wide-range speed adjustment while maintaining stable torque output, effectively accommodating frequent speed shifts in complex production cycles. The motor deploys Class F insulation rated for a maximum thermal tolerance of 155°C, supporting normal operation under ambient temperatures ranging from 0°C to 40°C and at altitudes no higher than 1000 meters. The IC04 cooling layout guarantees consistent heat dissipation throughout long-hour running, preventing winding overheating and insulation deterioration under continuous load. Two robust bearings are configured separately on the drive end and non-drive end, adopting models 6314C3 and 6309TC3 respectively to bear radial and axial loads steadily. The official maintenance protocol mandates annual inspection of universal lithium bearing grease one year after factory shipment; hardened or degraded grease requires refilling 1/2 to 2/3 grease volume for open bearing housings, while closed bearings demand full replacement to eliminate abnormal friction and wear. The overall net weight of the unit reaches 300 kilograms, with high-rigidity cast iron casing boosting structural stability against vibration and mechanical impact in harsh workshop environments.

Strict multi-stage quality verification is implemented across all ZDB-72 finished vertical dc motor units before delivery, covering winding dielectric strength testing, full-load current stability detection, rotor dynamic balance calibration, vibration amplitude testing and operational noise measurement. Every electrical parameter and mechanical dimension is executed in line with unified factory standards QXD.014.007, simplifying pairing with reducers, couplings, brakes and other transmission accessories. SIMO's closed-loop production management covers raw material screening, stator winding embedding, precision mechanical machining and finished product final inspection, eliminating potential electrical leakage, rotor shaking and abnormal heating risks. The shunt excitation design endows the ZDB-72 series with strong anti-interference capacity, resisting voltage fluctuation disturbance on industrial power grids and sustaining steady operation amid unstable power supply conditions. Its vertical structural design saves horizontal installation space, making it highly applicable to compact mechanical cabins and vertical assembly production equipment. Standardized spare part design streamlines aftermarket maintenance, shortens equipment downtime and cuts long-term operational maintenance costs for industrial manufacturers. The lubrication specification is fully standardized, allowing maintenance teams to follow unified grease replacement steps without customized operational training, greatly lowering the threshold of daily equipment management.

As a mainstream controllable drive component for heavy industrial vertical equipment, the ZDB-72 series has gained widespread recognition among domestic and global industrial clients for its reliable performance and flexible speed regulation capability. This mature vertical dc motor unites excellent speed adjustability, high-temperature resistance, mechanical durability and convenient maintainability, striking a balanced match between service life, operating stability and comprehensive cost. All specifications comply with universal international DC motor criteria, supporting both domestic heavy industry deployment and cross-border export engineering projects. Whether deployed in metallurgy, textile, papermaking, mining or general heavy machinery fields, the ZDB-72 vertical dc motor reliably fulfills long-duration variable-speed driving requirements, serving as a trusted vertical DC power solution for modern industrial electromechanical upgrading and automated production iteration.
