As a Chinese supplier, Mao Hui Machinery offers the original Lenze EVS9331-ES, which features a narrow cabinet installation design and supports the installation of an independent external heat sink (cold plate/through-hole cooling), effectively reducing heat accumulation in the cabinet and making it highly suitable for high-load continuous production lines.
It is compatible with both asynchronous and synchronous servo motors and includes a complete motion function module, allowing it to meet standard automation requirements without the need for an additional control board. It is equipped with a universal control terminal system, and all 9300 series drives use the unified GDC (Global Drive Control) software. Parameter backup, upload, fault diagnosis, and online debugging can all be completed with a single click.

The low-speed high-torque output and speed stability requirements for the spindle during the extrusion process are extremely high. The excellent overload capacity of Lenze EVS9331-ES can maintain a constant torque even when the raw material is not uniformly melted or the back pressure of the die head increases suddenly, preventing uneven discharge or melt rupture.
The printing and coating processes rely heavily on winding tension control and multi-axis electronic gear synchronization. The high-precision speed/position control algorithm built into the driver, combined with the electronic axis function, can effectively eliminate mechanical transmission gaps and ensure the accuracy of overprinting and the uniformity of coating thickness during high-speed operation.
The excellent anti-interference ability and thermal management design in the setting machine and web laying control can achieve smooth acceleration and deceleration curves, avoiding the breakage of fine fabrics or weight unevenness.
The high dynamic response performance of Lenze EVS9331-ES can instantly supplement torque during load changes, ensuring that the fly saw remains absolutely synchronized with the conveyor belt during follow-the-line cutting, and guaranteeing the flatness of the cut edge.
The driver can precisely control the position loop and speed loop to achieve stable positioning and soft landing of heavy-load materials, reducing mechanical structure collisions and impacts.
China Maohui Machinery has been developing Lenz drives for many years and possesses profound technical expertise and stable supply channels. Currently, our warehouse has a total value of tens of millions of brand-new Lenz E8200, 9300, E8400, etc. series in stock. The brand management over the years has won the trust and support of a wide range of domestic and international customers, helping them save time and costs. Some customers who purchase our products will be guided one-on-one by professional engineers to ensure timely and smooth machine operation, so as to avoid any production line delays. Moreover, the 9300 series is on the verge of being discontinued, and we have prepared a large quantity of in-stock products, which can be dispatched at any time.

We use anti-static shielding bags (or anti-static electrical film) as the inner packaging, and wrap the outside with 2-3 layers of high-density bubble film. We also use custom EPE pearl cotton shaping protection blocks or tight corner clamps to tightly secure the driver around the perimeter and the edge of the heat sink. The outer packaging box is made of multi-layer thickened corrugated cardboard box (5-layer or 7-layer BC corrugated is recommended), and the interior is filled with air column bags or high-density filling paper/bubble particles to absorb vibration. Widened industrial sealing tape and PET plastic strapping are used for stable sealing, and special attention is paid to the anti-collision protection of the front panel operation keys, display screen and the wiring terminals below. Ensure that the equipment remains intact in all aspects.
A: ES is the standard basic servo version for speed and torque control; EI has an inbuilt servo PLC; EP is a dedicated position controller; EK is used for electronic cam multi-axis synchronization. EVS9331-ES can meet most common heavy-duty single-axis drive requirements, with cost-effective performance.
A: Yes, we offer free access to the official Lenze operation manual and the Global Drive Control System (GDC) software. Our engineers can provide remote online guidance for parameter backup, upload, and troubleshooting.
A: There are in-stock products that will be shipped within 1-2 weeks after payment. As China Maohui requires professional testing before shipment, international express delivery usually takes 3-4 weeks to reach most countries.
