Brief Introduction

AIMIN Z4 series direct current motors are high-performance separately excited DC motors independently developed by Xi'an AIMIN Motor Co., Ltd., designed to meet the demands of modern industrial variable speed drive applications. Widely applied in metallurgical equipment, printing machinery, textile production lines, plastic processing machinery, mining auxiliary equipment and other industrial sectors requiring smooth stepless speed regulation, this series stands out for stable operation, compact structure and outstanding dynamic response. The Z4-160-31 model serves as a typical representative of the lineup, operating at 440V rated voltage with 30 kw motor amps reaching 77.8A, and supports dual rated speeds of 1500/3000r/min to satisfy diverse working condition requirements.

All Z4 series motors strictly follow JB/T6316 manufacturing standards and have obtained CE certification, meeting international quality and safety specifications. This motor adopts separate excitation design; the excitation current is controlled at 4.55A, enabling flexible independent adjustment of motor speed and torque. Equipped with IC06 forced ventilation cooling mode, the unit maintains stable temperature rise during long-time S1 continuous duty operation. With thermal class 155 insulation and IP21S protection grade, it can work reliably within an ambient temperature range of 0–40℃ at altitudes up to 1000 meters. Standard B3 mounting configuration brings great convenience for on-site installation and mechanical matching.

In terms of structural configuration, driving end and non-driving end are fitted with 6310/C3 and 6210/C3 bearings respectively, delivering excellent rotation stability and long service life. The whole machine weighs 250kg, featuring optimized rotor design, low rotational inertia and fast dynamic response. It can withstand frequent starting, braking and forward-reverse switching, perfectly adapting to cyclic and impact load working scenarios. Compared with traditional Z2, Z3 series DC motors, Z4 series achieves smaller volume, higher power density and lower vibration noise, greatly reducing maintenance frequency for end users.

Enterprises searching for reliable variable speed drive solutions consistently value accurate load matching, and proper parameter configuration directly influences system efficiency. When configuring drive systems for medium-power variable speed equipment, users must focus on matching power supply and load characteristics. Reasonable parameter matching guarantees that when running at full load, the stable operating state corresponding to 30 kw motor amps can be sustained without overheating or current fluctuation risks. The flexible speed adjustment range allows the motor to operate at either base speed or high-speed condition, effectively optimizing energy consumption under different production loads.

AIMIN Z4 DC motors have won global recognition for consistent quality and dependable after-sales support. Every unit undergoes strict factory testing to verify electrical performance, mechanical vibration and insulation performance before delivery. For overseas buyers looking for durable industrial DC drive equipment, the Z4-160-31 and other specifications within the Z4 series are cost-effective choices. Whether deployed in new production line projects or equipment renovation, users can gain stable long-term operation when the drive system is tuned to match the rated working condition where 30 kw motor amps serve as the core reference parameter. With strong overload capacity, flexible speed regulation and solid build quality, AIMIN Z4 DC motors remain a preferred power solution for industrial variable speed transmission worldwide.
