Ningbo Northstar Electromechanical Co., Ltd. supplies a Magnet Rotor for Brushless Motor that incorporates sintered NdFeB permanent magnets of grade N52 or N42UH within a steel housing. The rotor is described as a precision‑balanced multi‑pole assembly with an anti‑corrosion coating, designed for high‑efficiency motor applications such as electric‑vehicle drives and industrial servos. It is compatible with standard NEMA and IEC frame sizes and is offered with export‑grade packaging to protect the magnetic components during international transit. The source notes a harbour‑level trust tier but records a zero response rate, meaning no buyer messages have been answered yet.
In the motor industry, N52 magnets provide some of the highest energy densities, typically delivering a magnetic flux density around 1.2 T and a coercivity near 12 KA/m, while N42UH offers a balance of strength and temperature resistance. Typical rotor dimensions for this class range from 100 mm to 150 mm in diameter and 120 mm to 180 mm in length, with a weight around 0.5 kg, although exact figures depend on pole count and housing design. The anti‑corrosion coating is usually an epoxy or nickel‑copper layer that extends service life in humid or high‑temperature environments.
Potential buyers include motor manufacturers, OEMs of robotics and drones, and renewable‑energy system integrators who need reliable high‑speed rotors. The listing does not specify minimum order quantities, lead time or payment terms, so those details must be clarified with the supplier before commitment. Likewise, certification status, such as ISO 9001 or RoHS compliance, is not listed and should be requested during the quotation stage.

Start by confirming the supplier’s ability to deliver the exact magnet grade and coating you require, and request a sample or a third‑party test report that validates coercivity and temperature performance. Clarify whether the rotor will be supplied as a fully assembled unit or as separate magnet blocks for in‑house integration.
Discuss logistics early, specifying the Incoterm (for example FOB Ningbo port) and any special handling needed for the steel‑housing rotor to avoid damage during transport. Verify the production lead time once the order quantity and custom specifications are finalised, and align payment terms with your company’s risk policy.
Implement a quality‑control plan that includes visual inspection of coating integrity, dimensional verification against the supplied drawings, and magnetic field testing at operating temperature. Request an on‑site inspection or a pre‑shipment inspection certificate, and ensure that all export documents such as commercial invoice, packing list and certificate of origin are prepared by the supplier.
