Brief Introduction

The AIMIN Z4 series of direct current electric motor foot mounting is engineered to meet the most rigorous demands of modern industrial operations, offering unmatched precision and reliability for applications ranging from metallurgy to textile manufacturing. Developed by Xi'an AIMIN Motor Co., Ltd., this series is built to deliver consistent torque, dynamic speed control, and long-term performance in environments where downtime is not an option.

At its core, the Z4 series electric motor foot mounting features a separate excitation (SEP.180) design, which allows independent control of the armature and field circuits for smooth acceleration, precise speed regulation, and rapid deceleration-critical for processes like rolling mill drives and high-speed production lines. The Z4-280-31B model, a key offering in the range, provides a rated output of 75 kW at 400 V, with a full-load current of 218 A and a dual-speed range of 450/1350 r/min. This flexibility enables it to adapt seamlessly to both low-torque, high-speed and high-torque, low-speed tasks, reducing the need for additional mechanical components and simplifying system design.

Constructed for rugged reliability, the Z4 series boasts a Class F (155°C) thermal rating and an IP21S protection class, safeguarding internal components against dust and water drips in typical industrial settings. Its IC 06 cooling system ensures efficient heat dissipation during continuous S1 duty cycles, preventing thermal overload and extending service life. The Z4-280-31B uses premium C3 clearance bearings-6320/C3 on the drive end and 6218/C3 on the non-drive end-to minimize vibration and reduce maintenance, while its standard IM B3 foot-mounted design ensures easy installation and compatibility with existing equipment. Weighing 1460 kg, the motor's heavy-duty frame is compliant with JB/T6316 standards, ensuring mechanical stability and adherence to strict quality benchmarks.

Backed by CE certification and AIMIN's global service network, the Z4 series delivers tangible operational benefits, including reduced mechanical wear and optimized energy efficiency. Whether powering a textile machine or a material handling conveyor, the AIMIN Z4 series DC electric motor foot mounting combines technical innovation with proven durability, making them a trusted choice for industrial drives worldwide.
