Z4-355-11 Direct Current Motor 400v 200kw

Brief Introduction

The Z4-355-11 is a robust direct current motor 400v engineered by Xi'an SIMO Motor for demanding industrial variable-speed applications. Designed to meet JB/T6316 standards and certified with the CE mark, this 200kW motor operates at 400V, drawing 550A at rated load, with a variable speed range of 500 to 1500 r/min. It employs a 220V separate excitation system with 20.5A excitation current, paired with Class F (155℃) thermal insulation, IP21S protection, and IM B3 foot-mounted configuration for flexible installation.

Built for continuous S1 duty cycles, the motor 400v uses premium bearings (6324/C3 drive end, 6224/C3 non-drive end) to minimize friction and extend service life, while its enclosure withstands 0–40℃ ambient temperatures and altitudes up to 1000m.

Core Strengths

Superior Speed Regulation: The variable-speed design enables precise torque and speed adjustment, supporting dynamic load changes without sacrificing efficiency.

Long-Term Reliability: High-grade components and optimized thermal management reduce maintenance needs, ensuring consistent performance in harsh environments.

Flexible Excitation Control: The separate excitation system enhances stability, making it ideal for processes requiring accurate speed holding or overload tolerance.

Key Industrial Applications

Metallurgical Processing: Powers rolling mills, coilers, and straightening machines, where variable torque control ensures consistent metal forming quality.

Heavy-Duty Material Handling: Drives overhead cranes, hoists, and port equipment, delivering reliable performance under frequent start-stop cycles and variable loads.

Paper & Printing Machinery: Used in winders, calenders, and coating lines, providing smooth speed regulation for continuous production processes.

Mining & Cement Equipment: Supports crushers, kiln drives, and conveyor systems, withstanding dust and vibration while maintaining operational stability.

Designed for uncompromising performance and longevity, the Z4-355-11 DC motor 400v from Xi'an SIMO Motor stands as a benchmark for industrial variable-speed power solutions. Its 200kW rated power, combined with a 500–1500 r/min speed range and precise 220V separate excitation, delivers exceptional torque control and operational stability, even under heavy and fluctuating loads. Built to JB/T6316 standards and certified with the CE mark, it features Class F thermal insulation, IP21S protection, and high-quality bearings to ensure reliable S1 continuous-duty operation in temperatures from 0–40℃ and altitudes up to 1000m. Low maintenance requirements, robust construction, and versatile adaptability make it the ideal choice for critical applications in metallurgy, material handling, mining, and general machinery, offering long-term efficiency and value for industrial operations worldwide.
