APICAL® Polyimide Film Is the Right Choice.
APICAL® Polyimide: The Right Choice for Motors
In demanding applications, such as locomotive traction motors, temperatures can soar to 400C or 500C in a short period of time. High-performance motors, generators, and transformers often operate under extremely harsh conditions. APICAL® Polyimide Film is the right choice for these applications, easily enduring high heat without loss of mechanical or dielectric strength.
Advantages of APICAL® Polyimide for Motors
Traditionally, mica or glass were the primary materials used for insulation. However, APICAL® Polyimide can be wrapped thinner and tighter in motor windings, allowing for the use of thicker, higher current-carrying conductors. This advancement makes APICAL® Polyimide the ideal polyimide for motors, enhancing their efficiency and performance.
Versatile Applications
APICAL® Polyimide Film is utilized in various demanding environments beyond locomotives. You’ll find it in aircraft engines, mining equipment, and within the utility and petroleum industries. Its versatility makes it the preferred polyimide for motors. Typical applications include armature coil insulation, rotor and stator slot liner insulation, and magnet and thermocouple wire insulation. This wide range of uses underscores the effectiveness of APICAL® Polyimide as the go-to polyimide for motors in high-performance scenarios.
