Hairpin E-motor is significantly transforming the industry
The hairpin electric motor is a cutting-edge technology that has been developed to address the limitations of traditional electric motors. It utilizes a unique stator winding configuration that features hairpin-shaped copper wires, which are pre-formed and inserted into slots in the stator core. This design creates a more compact, efficient, and robust motor with enhanced thermal performance, higher power density, and lower resistive losses.
The hairpin e-motor's construction allows for increased slot fill, reducing the need for additional copper and improving efficiency, while also enabling the use of thinner laminations, which helps to reduce noise and vibration levels. The hairpin winding technique offers better control over the shape and size of the conductors, resulting in a more uniform distribution of magnetic forces and reduced torque ripple. Additionally, the hairpin e-motor's design enables better heat dissipation, due to its increased surface area, leading to longer lifespan and greater reliability.
Its benefits make it an ideal choice for various applications, including electric vehicles, industrial machinery, and renewable energy systems. Its high performance, lightweight, and reliability have made it increasingly popular in the automotive industry, where it is being used to power electric vehicles with greater efficiency and range. The hairpin electric motor has become a groundbreaking technology that promises to transform the electric motor industry, offering a wide range of advantages over traditional motors.

Less waste material
Compared to traditional uncoating methods, such as mechanical stripping or chemical etching, laser uncoating offers several advantages. For example, it produces less waste material, requires no solvents or chemicals, and can be easily automated for high-volume production.
Greater precision and control
Laser uncoating enables greater precision and control over the uncoating process, reducing the risk of damage to the underlying wire. This can result in improved product quality and reliability, particularly in applications where electrical conductivity and signal integrity are critical.
