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.
Critical Properties for Motor and Generator Insulation

High Temperature and high perferormance Insulation
APICAL® Polyimide Film Is the Right Choice.
A typical locomotive traction motor, when stalled, can reach a temperature of 400°C to 500°C in just a short period of time. High performance motors, generators and transformers are often integrated into systems that must operate under extremely harsh conditions. Yet used within these devices, APICAL® Polyimide easily endures this heat without loss of mechanical or dielectric strength.
Where mica or glass were once the only material available, APICAL® Polyimide can be wrapped thinner and tighter in motor windings allowing thicker, higher current carrying conductors to be used. You’ll also find APICAL® Polyimide in aircraft engines, mining equipment and in the utility and petroleum industries. Typical applications include armature coil insulation, rotor and stator slot liner insulation and magnet and thermocouple wire insulation.
The critical properties of APICAL® Polyimide that make it ideal as a motor and generator insulation include its broad temperature cycling range (-269°C to 400°C), it’s superior dielectric properties (dielectric strength of 7,800v/mil), its outstanding mechanical durability, coupled with its high thermal index (240°C-Electrical) and good chemical resistance.
