What is the overload capacity for the metal rolling mill DC motor?

Second kind (B) motors can endure 115% rated power overload continuously. They can also run at 125% rated power for two hours after rated overload, provided temperature rise remains within regulated limits.

What standards does the motor comply with?

The motor complies with GB755, IEC60034-1, and JB/T9577 regarding the rating and performance of rotating electrical machinery.

AI-Powered supplier vetting

SummaryShanghai Fortune Electric Co., Ltd. is identified as a China-based limited company with manufacturer/factory status, although another record describes the associated industry as wholesale and retail and the company type as a trading company. Its stated product scope includes medium- and high-voltage motors, vertical motors, induction melting furnaces, and continuous casting equipment or parts. The supplier reports ISO 9001 certification, eight production lines, 11–20 years of R&D engineer experience, 6–10 quality-control staff, broad export coverage, and self-operated import/export rights. It states customer satisfaction as a mission and describes professional and timely service, but no concrete after-sales process or service performance is documented. Production capacity and export experience are supported, while customization capability and financial credibility cannot be conclusively assessed from the available non-financial evidence. Trade records identify an Indian buyer and products related to...

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and limited company in Shanghai, China, while a separate record classifies the company as a trading company in the wholesale and retail industry. This creates a mixed classification, but the manufacturer/factory designation is directly documented.

CertificationsThe supplier is reported to hold ISO 9001 certification for its management systems. This is explicit evidence of certification relevant to quality-management practices.

R&D capabilityThe supplier reports 11–20 years of total R&D engineer experience and offers a technically broad range of motors, vertical hollow-shaft products, induction melting furnaces, and continuous casting equipment. This supports engineering capability, but no patents, new-product development results, or other direct innovation metrics are provided.

Production capacityThe supplier reports eight production lines, 6–10 quality-control staff, a one-month off-peak lead time, and a two-to-three-month peak-season fulfillment time. Its stated product range and trade records covering furnace and continuous-casting components further support production activity, although the slices do not verify capacity by product or actual output volumes.

Client casesThe supplier states that its products are distributed across numerous countries and regions, and trade records identify BRIGHT METALS INDIA PRIVATE LIMITED as a buyer for holding-furnace and continuous-casting-related products. The evidence supports international customer activity, though only one named buyer is provided and no project outcomes or customer references are documented.

Product Q&A

Q:What are the standard rated voltages for this motor?

Standard voltages include 440V, 550V, 660V, and 750V. Other voltage classes can be derived based on specific situations but must be negotiated when ordering.

Q:What is the basic excitation style of the motor?

The basic excitation style is separately excited with an excited voltage of 220V. Other classes can be derived according to specific situations upon negotiation.

Q:What is the maximum altitude for operation?

The maximum altitude above sea level for operation is 1,000 meters.

Q:Can the motor be used in foul situations?

Yes, the motor can be installed in foul situations, provided the correct cooling method and defense class are chosen. Special situations require negotiation.

Q:Is the motor suitable for 3-phase bridge rectifier power supply?

Yes, the motor is suitable for 3-phase bridge rectifier power supply and can also adopt power supply from a DC generator.
