Motor Stator Market Analysis

The motor stator is a key component of electric motors in new energyvehicles, responsible for converting electrical energy into mechanical energyto drive the vehicle. It is composed of the stator core, stator windings,insulation materials, and auxiliary standard parts such as lead wires.Typically stationary in the motor, the stator generates a rotating magneticfield when current flows through the windings, which interacts with the rotorof the motor. Under the influence of this magnetic field, the rotor rotates anddrives the wheels, ultimately enabling vehicle movement. Broadly defined, thestator refers to the stationary part of the motor, including the core andwindings; in a narrower sense, it refers specifically to the stator core. Thisreport covers the stator market, including generator stators and assemblies. Asstators become increasingly important in NEVs, the global stator market iswitnessing rapid growth. The NEV motor stator market is driven by severalfactors, including rising global NEV sales, government support for electricvehicle development, technological advancements improving motor efficiency, andthe need to reduce production costs.

In the NEV motor sector, the main differencebetween flat-wire and round-wire motors lies in the stator winding structure.The shape of the winding directly impacts critical parameters such as motorperformance, size, and efficiency. Flat-wire motors use rectangular conductorsfor windings, which fit better into the motor slots and increase the slot fillfactor (SFF)—a measure of how densely the windings fill the slot. A higher SFFleads to better power density, enabling higher output power within the same orsmaller volume and weight. In contrast, round-wire motors use multiple fineround wires, resulting in a lower SFF, typically below 50%. Flat-wire windingsusually achieve an SFF above 70%. The higher the SFF, the more efficiently themotor can use the slot space, helping reduce thermal losses and improveefficiency. With the rapid development of NEVs and increasing demand for highperformance, flat-wire motors are becoming the mainstream choice. Their higherpower density, better heat dissipation, and stronger short-circuit resistancehave led to widespread adoption in the NEV market. Many leading motormanufacturers are investing in flat-wire motor production processes to meet thegrowing demand for high-performance motors.

Motor StatorSupply Chain Analysis

The raw materials for motor stators include silicon steel sheets, copper,and aluminum. Silicon steel sheets, the main material for stator cores, offergood magnetic permeability, low energy loss, and high saturation magneticinduction. The quality of the core material directly determines motorperformance; in particular, high-efficiency motors require high-grade siliconsteel sheets. Major suppliers include large steel producers like Baosteel andArcelorMittal. Copper is the primary conductive material used in statorwindings. High-quality copper improves conductivity and reduces energy loss.However, fluctuations in copper prices significantly affect manufacturingcosts, prompting companies to prioritize long-term partnerships with suppliers.In certain small or specialized motors, aluminum windings or components areused instead of copper to reduce weight. Though less conductive than copper,aluminum offers cost advantages and is widely used in power tools and consumerelectronics.

In the midstream of the motor stator market is the manufacturing ofstator and rotor components. Stators and rotors are the core elements ofmotors, determining their overall structure and performance. Stator productioninvolves complex processes such as winding, punching, and insulation treatmentto ensure stability under high efficiency and high-temperature conditions.Windings—made of copper or aluminum—are the conductive parts of the stator, andtheir arrangement (random, flat-wire, etc.) significantly affects motorperformance. The midstream market also includes parts such as end caps andbearings. End caps protect the motor's internal structure, while bearingsensure stable rotation. These components have high precision and durabilityrequirements and significantly affect motor lifespan. Leading bearingmanufacturers such as Schaeffler and SKF are continually optimizing designs tomeet demands for high-load and high-speed operation.

The downstream segment of the motor stator market includes motormanufacturers who design and produce motors of various specifications andperformances based on application requirements. These manufacturers investheavily in R&D for stator design, optimizing for market demand, performancemetrics, and cost. For example, NEV motor production emphasizes high powerdensity and heat management. Stator assembly is a core process in motorproduction, encompassing winding, core assembly, and insulation treatment. Advancedstator production lines are equipped with automated winding machines, weldingrobots, etc., to enhance production efficiency and consistency. Quality testingspans the entire production process, including electrical tests (e.g.,dielectric strength, turn-to-turn insulation) and mechanical tests (e.g.,dynamic balancing), ensuring that stators meet specifications. Quality controlis critical for improving motor performance and reducing defect rates. Majormotor manufacturers span various application fields, such as home appliances,power tools, industrial equipment, and NEVs. For instance, Siemens and ABBfocus on industrial motors, while BYD and Tesla are heavily involved in NEVmotor development.

Global AutomotiveMotor Stator Market: Competitive Landscape

The global stator market exhibits a highlyfragmented and technology-driven competitive landscape. Internationalmanufacturers hold advantages in technological R&D and market share,especially in the industrial and high-end motor sectors, while regional playersremain competitive in terms of cost and production scale. Countries such asChina, Japan, and India are leading the adoption of electric vehicles andadvanced manufacturing technologies, generating significant demand forhigh-speed motor stators. Additionally, the presence of major marketparticipants and increasing focus on energy efficiency and sustainability areexpected to drive regional market growth.

At the same time, with breakthroughs in keyproduction technologies for flat wire motor stators, global motor manufacturersare increasingly seeking to purchase production lines to achieve statorself-sufficiency. On August 26, Inovance Technology announced that itssubsidiary, Suzhou Inovance United Power System Co., Ltd., plans to invest inthe construction of a new energy vehicle parts production base in Suzhou. Thebase will include workshops and supporting facilities for stators, rotors,motor controllers, power supplies, and assemblies, with a total investment notexceeding 5 billion yuan.
