Process For Motor Stator Coil Winding
Winding technology the stator coils of an electric motor lamination is a crucial step in the manufacturing process. The stator is a stationary part of the motor that houses the coils, which generate a magnetic field when energized, leading to motor operation.
Our experience team evaluates the motor design drawings and specifications. Understand the required number of turns, wire gauge, coil arrangement, and other relevant parameters.
Design and manufacture the winding tooling or fixtures required for the specific motor design. This includes the creation of coil forms or bobbins that hold the wire during the winding process. Our tooling should be precise and tailored to the motor specifications.
Conduct a trial winding using the manufactured tooling to verify that the design meets the specifications. This step allows engineers to identify and address any issues or improvements needed in the winding process before full-scale production.
After successful trial winding, and setting up the winding machine, we may be offered a manual or automated winding system depending on the scale of production. Then, start the winding process by guiding the copper wire onto the coil form.
If required, the stator may impregnation with insulating varnishes or resins. In addition, we offer coi shaping, electrical performance testing, and electrical testing and inspection.
Lamination Stacks Winding Capabilities
There are several types of winding methods in electric motor coil, each suitable for different applications and motor designs. We use different types of electric motor coil winding including centralized winding, distributed winding, etc.
Centralized Winding
Concentrated winding involves the use of one or a few rectangular frame coils in motor construction.
Following the winding process, the coils are wrapped and shaped with yarn tape, then immersed and dried before being embedded into the salient magnetic pole’s iron core.
This winding technique is commonly employed in the excitation coils of DC motors, general-purpose motors, and as the main pole windings in single phase shaded pole motors, providing efficiency and reliability in various motor applications.
The stator of the motor adopting distributed winding has no convex pole palm, and each magnetic pole is composed of one or several coils embedded and wired according to a certain rule to form a coil group. According to the different forms of embedded wiring arrangement, distributed windings can be divided into two types: concentric and stacked.
Concentric windings feature variously sized rectangular coils within the same group, embedded and arranged in a circular pattern around a common center. This winding type, divided into single-layer and multilayer configurations, is commonly used in the stator windings of single-phase motors and certain low-power three-phase stators for efficient coil distribution.
Lap connection windings come in two types: single-stacked and double-stacked. Variations include cross-type, concentric cross-type, and single- and double-layer hybrid types based on wiring methods.
Larger three-phase asynchronous motors typically use double-stacked windings, while smaller motors often employ single-stacked or its derivatives, with single-stacked winding being less common.

Motor Winding FAQS
The primary purpose of motor stator winding is to create a magnetic field that interacts with the rotor to produce mechanical motion. When electric current is applied to the stator winding, it induces a magnetic field that interacts with the rotor’s magnetic field, resulting in the rotation of the motor shaft.
Copper and aluminum are the most common materials for motor stator winding due to their excellent electrical conductivity. Copper is preferred for high-performance applications, while aluminum is often used in more cost-sensitive situations.
Motor windings play a crucial role in electric motor functionality. They generate magnetic fields essential for inducing rotor motion, resulting in mechanical work.
Efficient winding design optimizes motor performance, enhancing factors such as torque, speed, and energy efficiency.
Proper concentrated and distributed winding materials and insulation ensure reliability and longevity in motor operation.
Stator rotor windings are widely utilized in various industries, including manufacturing, automotive, aerospace, and renewable energy. They are integral components in electric motors, generators, and alternators, essential for applications ranging from industrial machinery and transportation to power generation and renewable energy systems.
Common methods for detecting faults in motor windings include insulation resistance testing, megger testing, and vibration analysis. Regular maintenance and testing help identify potential issues before they lead to motor failure.
Types of flat wire windings:
I-pin winding, featuring straight pins arranged in a parallel pattern.
X-pin winding, with pins crossed at the center, forming an X-shape.
Hair-pin winding, where the wire is folded back on itself, resembling a hairpin.
S-winding, utilizing a sinusoidal pattern for efficient space utilization.
