Brief Introduction

The Z2 series DC motor (exemplified by model Z2-91 shunt type dc motor) is a robust, high-performance industrial drive developed by Xi'an AIMIN ELECTRICS Co., Ltd., a leading manufacturer in the global electric motor industry. Engineered for reliability and efficiency, this shunt-excited DC motor is designed to meet the demanding requirements of heavy-duty industrial applications, offering precise speed control and consistent torque delivery.

With a rated power output of 55 kW, a rated voltage of 220 V, and a rated current of 284 A, the Z2-91 shunt type dc motor delivers powerful performance while maintaining high energy efficiency. Its speed range of 1500/2000 r/min enables flexible operation across various load conditions, making it suitable for applications that demand variable speed control, such as metal rolling mills, hoists, machine tools, and paper production lines. The motor adheres to S1 continuous duty cycle standards, ensuring uninterrupted operation under sustained loads, which is critical for industrial production continuity.

Built to withstand harsh operating environments, the Z2 series motor features an IP22 protection rating that safeguards against accidental contact and the ingress of solid foreign objects, while its thermal class 155 (insulation class F) provides excellent resistance to thermal stress, extending the motor's service life. It is certified to operate reliably in ambient temperatures ranging from 0~40°C and at altitudes up to 1000 m, making it adaptable to diverse geographic and industrial settings. The IC01 cooling method ensures effective heat dissipation, further enhancing operational stability during prolonged use.

Precision engineering is at the core of the Z2 series design. The motor is equipped with high-quality bearings: 6314/C3 on the drive end (D.E.) and 6313/C3 on the non-drive end (N.D.E.), which reduce friction, minimize vibration, and extend maintenance intervals. With a net weight of 650 kg, this Z2-91 shunt type dc motor features a rugged IM B3 mounting structure (foot-mounted), ensuring stable installation and alignment, which is essential for heavy-load applications. It complies with CE standards, reflecting its adherence to international safety and quality requirements.

Manufactured under the strict quality control system defined by standard Q/XD.514.017, each Z2 series motor undergoes rigorous testing to ensure consistent performance and durability. The model Z2-91 shunt type dc motor, produced in January 2026 (product number: Z26014045001), represents the latest iteration of AIMIN's Z2 series, combining decades of engineering expertise with modern manufacturing techniques to deliver a reliable, cost-effective solution for industrial power transmission.
