Frameless Torque Motors Encapsulated Epoxy Resin Potting

In the future, there will be a high demand for remotely controlled or autonomous AI Robotics that need to maintain balance like humans, use joints flexibly like humans, perform daily household chores, carry heavy loads, and complete tasks efficiently and accurately. Therefore, each joint motor must be designed to be smaller and tighter to reduce weight, make legs, arms and fingers more flexible and easier to control, and at the same time need the motor to operate efficiently, stably and accurately.

The impact of temperature rise, vibration, and centrifugal force are motors during operation. The accumulation of these negative factors over time will cause winding loosening and insulation material deterioration, which in turn will lead to insulation damage due to friction between coils and wires, negatively affecting the stability and working life of the motor.

force are.

One process to improve the operating stability and life of motors is to encapsulate the motor windings with polymer, and epoxy is the most common material for this purpose. The strong, insulating epoxy encases the windings or cores inside, providing anchoring and shock resistance while keeping these parts isolated from "harmful" substances in the environment. The high thermal conductivity of epoxy also helps the windings to conduct heat to the external environment, thus ensuring a more stable overall motor temperature.

We has developed a suite of polyurethane / epoxy encapsulated and potting products specifically for the motor manufacturing industry.  Our materials for Motors/Coils/Power Supply are formulated with the following properties:

•   Underwriters Laboratories UL 1446 recognition: wWe has numerous of a UL 1446 recognized insulation system potting compound component to choose from to choose for use up to 180C (Class H).

•   Low viscosity: allows our systems to penetrate and release air from even the tightest coil and slot windings, enabling many of our customers to eliminate varnishing from their manufacturing process.

•   Excellent Thermal Regulation: Resistance to temperature shocks: able to work in a wide range of temperatures, high or low.

• Outstanding Thermal Conductivity: our filled epoxy materials excel at transporting and dissipating heat from motors and other coil windings, a reduction in core temperature is always achieved.

• Process friendly: our materials are designed to have mix ratios, viscosities, gel times that are friendly to process and automate.they are easy to handle and good for automated production.
