Z Series High Volt Dc Motor

PUTAI Z Series High Voltage DC Motors cover 40–3,000 kW for industrial equipment OEMs, project contractors, distributors, and maintenance teams. Typical applications include rolling mills and heavy industrial machinery using compatible DC drives.

Frame and Electromagnetic Design
Frame structure and electromagnetic components support industrial DC drive applications. Frame dimensions and shaft interfaces are important for equipment integration and motor replacement.

DC Drive Compatibility
Motor ratings must match the DC supply, excitation system, required speed, and driven load, particularly in variable-speed applications.

Cooling and Operating Conditions
Cooling and protection configurations should suit the installation environment and operating duty. Frequent starting, braking, or load changes require consideration of the applicable duty rating.
 

Rolling Mills: Main and auxiliary drives for rolling mill equipment where adjustable speed and DC drive compatibility are required.

Metallurgical Production Lines: Drive systems for metal-processing equipment requiring controlled operating speed and torque.

Heavy Industrial Machinery: High-power DC drive applications where motor speed, load characteristics, and existing drive systems must match the equipment requirements.

OEM Motor Supply
PUTAI supports OEM integration and project-based motor supply. Key coordination points include:
• Electrical interface: Rated power, armature voltage, speed, excitation, DC drive arrangement, and duty.
• Mechanical integration: Frame, mounting dimensions, shaft extension, keyway, and coupling.
• Cooling and protection: Configuration suited to the equipment and installation environment.
• Technical documentation: Available data sheets, outline drawings, connection information, and applicable inspection records.

• Customers can provide equipment drawings or project specifications to coordinate the motor configuration before production.

Replacement Motors for Existing Equipment
Replacing a DC motor requires more than matching rated power. Electrical ratings, excitation, speed, mounting dimensions, shaft interfaces, cooling, and drive compatibility must also be checked.
Useful information includes the original nameplate and model, motor photographs, rated power and voltage, current and speed, excitation details, shaft and mounting measurements, cooling method, and existing drive or rectifier information. Drawings and maintenance records can help when nameplate details are incomplete.

Distributor Supply and Customization
PUTAI supplies DC motors, AC motors, medium-voltage motors, starters and drives, windings, and motor components. Electrical ratings, mechanical interfaces, cooling, protection, and documentation can be coordinated according to the agreed project requirements.
