Z560-4B (U) Direct Current 660v Motor 750kW

Brief Introduction

The Z560-4B(U) 660v motor is a high-performance direct current motor from SIMO Motor, purpose-built to deliver reliable, heavy-duty power for the most demanding industrial environments. With a robust design and advanced engineering, this motor is the ideal choice for applications requiring precise control, high torque, and continuous operation, such as metal processing, mining equipment, and large-scale material handling systems.

At its core, the Z560-4B(U) boasts a rated power of 750 kW and a rated current of 1215 A, providing exceptional power density and efficiency. Its speed range of 500/1200 r/min offers unmatched operational flexibility, allowing seamless adaptation to varying load requirements. The separately excited field winding, with an excitation voltage of 220 V and an excitation current of 33.5 A, ensures stable and responsive performance, even under dynamic load fluctuations, making it perfect for processes that demand precise speed regulation.

Durability is at the forefront of the Z560-4B(U) 660v motor design. It features an IP44 ingress protection rating, which shields the internal components from dust and water splashes, ensuring reliable operation in tough factory conditions. The cooling system adheres to the IC W37A86 standard, utilizing a highly efficient ventilation design to dissipate heat effectively during prolonged use, preventing overheating and extending component life. The motor's insulation system is rated at TH.CL. 155, offering superior thermal stability and resistance to electrical stress, which significantly reduces maintenance needs and downtime.

To ensure maximum reliability and smooth operation, the Z560-4B(U) is equipped with premium SKF bearings: a NU240ECM bearing on the drive end (D.E.) and a 6238/C3 bearing on the non-drive end (N.D.E.). These bearings are selected for their high load-carrying capacity and exceptional durability, ensuring minimal friction and vibration even under heavy loads. The motor is engineered to operate in ambient temperatures from 0–40°C and at altitudes up to 1000 m, making it suitable for deployment in diverse global locations.

Compliant with the JB/T 9577 industry standard and CE certified, the Z560-4B(U) 660v motor meets the highest international quality and safety benchmarks. With a net weight of 7320 kg and a B3 mounting configuration, it is designed for easy integration into heavy-duty industrial setups. Manufactured in January 2026, this motor represents the pinnacle of SIMO's expertise, combining robust construction, precision control, and long-term reliability to drive productivity and efficiency in modern industrial operations.
