CRRC PDTY732X Series Wire Drawing Machine Motor

CRRC PDTY732X series is a high-torque wire drawing machine motor tailored for thick metal wire processing, delivering a torque range of 0-2400 Nm and a speed range of 0-800 rpm (covering the 15-75kW power scope), paired with high load-bearing capacity and durable components.
Equipped with reinforced bearings and a robust casing, this motor is engineered to handle the heavy-load, long-hour operation conditions of thick wire drawing (e.g., large-diameter industrial steel wires).
As a core model in our heavy-duty wire drawing lineup, it integrates seamlessly with large-scale thick wire production lines, ensuring stable traction and compatibility with industry-standard heavy processing equipment.
We offer comprehensive life-cycle support for the PDTY732X series, including equipment supply, on-site installation and commissioning, maintenance training, spare parts provision, and ongoing technical troubleshooting services.

Advantages of CRRC PDTY732X Series Wire Drawing Machine Motor

This wire drawing motor series covers a 15-75kW power range and 5 distinct torque/speed combinations, enabling broad application compatibility that adapts to fine, medium, thick, heavy-gauge, and extra-thick wire drawing processes for materials including copper, aluminum, iron, and precious metals.
Its precision design—featuring a balanced rotor and optimized heat dissipation—ensures stable & high-quality output, delivering consistent power delivery to reduce wire diameter deviation and improve finished product qualification rates.
With structural damping and a compact frame, the motor adopts a low-noise & lightweight design: this minimizes workshop noise pollution, while the lightweight construction lowers the load of equipment installation and daily operation.
Built with reinforced components like bearings and conductors to extend service life, the motor also features a modular layout that enables durable & easy maintenance, supporting quick disassembly, part replacement, and routine upkeep.
Boasting proven market reliability, over 1,000 units have been deployed in domestic metal processing enterprises; mature quality control systems further guarantee stable performance and consistent supply for end users.
