Lap Winding vs. Wave Winding: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on February 7, 2024
Lap Winding involves multiple parallel paths in the armature circuit, suitable for high current, low voltage; Wave Winding has two parallel paths, ideal for high voltage, low current applications.
Key Differences
Lap Winding is characterized by its parallel path configuration in the armature of a DC machine, making it suitable for high-current applications. Wave Winding is designed with only two parallel paths, regardless of the number of poles, making it more suitable for high-voltage, low-current scenarios.
In Lap Winding, each coil is connected in series with adjacent coils under the next pole, resulting in multiple parallel paths in the armature circuit. Wave Winding connects the coils in a way that forms a single continuous path, spanning all poles in a wave-like pattern.
Lap Winding is generally used in electrical machines that require large current outputs at lower voltages, such as in heavy-duty motors and generators. Conversely, Wave Winding is used in machines where high voltage and low current are needed, like in high-speed electrical machines.
The design of Lap Winding allows for more number of conductors in the armature, which increases the current capacity. In contrast, Wave Winding has fewer conductors but a higher voltage capacity due to its series configuration.
Maintenance and winding complexity differ; Lap Winding is more complex and harder to maintain due to its multiple connections, whereas Wave Winding, with fewer connections, is simpler and easier to maintain.
