| 1. Product Structure | Also known as Reinforcement Ring, Fiberglass Ring, Epoxy Ring. Reinforced by high-performance epoxy resin and fiberglass, the material is directionally distributed to form a three-dimensional network structure through a specific production process, and then manufactured through winding, curing, turning, grinding, cutting, and other processes. Currently divided into multiple product series based on different temperature resistance and tensile strength levels. |
| 2. Core Performance - Excellent Basic Characteristics | High temperature resistance, high strength, good insulation, light weight, corrosion resistance, suitable for long-term starter operation. |
| 2. Core Performance - Outstanding Insulation Performance | With an integrated insulation design, epoxy resin naturally possesses insulating properties, eliminating the need for additional coatings. Boasts high volume resistivity, effectively eliminating the risk of short circuits between commutator segments. Exhibits excellent arc resistance and can withstand high electric field strength, making it suitable for high-voltage motor applications. |
| 2. Core Performance - Strong Environmental Adaptability | Excellent high-temperature stability, no softening or deformation at 250°C; resistant to damp heat aging, good compatibility with metal commutator segments, preventing loosening caused by temperature-induced deformation. |
| 2. Core Performance - Flexible Adaptability | Supports customized dimensions, allowing for flexible adjustment of various specifications of inner diameter and thickness, suitable for all types of starters ranging from micro to large. |
| 3. Main Applications | As a key component of a starter or engine starter motor, it is mainly installed across the ends of the armature coil to overcome the pulling force of centrifugal force on the coil during high-speed rotation, prevent coil deformation or insulation layer damage, eliminate faults such as short circuits and electrical leakage, and ensure the safe and stable operation of the starter and related equipment. Widely used in the starter motor industry. |
