New B8650 impregnation machine for sustainable impregnation of electrical motors

Impregnation Processes for more performance of electric motors

The release of the B8650 impregnation machine enhances the electrical component manufacturing, specifically targeting the impregnation of windings in rotors, stators, and coils used in electric motors. This new machine is designed for small to medium production volumes and offers superior insulation, improved performance, and extended operating life for these critical components. The insulation system provided by the B8650 plays a pivotal role in the efficiency and longevity of electric motors, making heat management a critical aspect of its design.

The impregnation process is essential for closing and sealing voids in a component between wires using insulating material like epoxy resins, unsaturated polyester and polyetherimides or silicones. This process significantly enhances the overall performance and durability of electrical windings by providing better insulation and preventing vibration.

By filling these voids, the windings receive an additional layer of protection, which not only increases their thermal conductivity but also contributes to a better electrical isolation. One of the key advantages of impregnation is ensuring efficient heat exchange during normal operation which enhances resistance of the motors to stress and temperature load. The enhanced isolation will increase the PVID resistance (Partial Voltage Inception Discharge) within the windings ensures a longer and more reliable service life for the electric motors.

New machine concept B8650 for small to medium production processes

The new B8650 machine features advanced technology to meticulously manage heat distribution for both stators and varnish. This careful management ensures uniform resin flow and superior insulation properties.

The machine is designed with versatility in mind, capable of processing in automatic, with a programmable and full configurable process, one or two components simultaneously. This flexibility makes it an ideal choice for manufacturers handling small to medium production volumes. Despite its compact size, the B8650 does not compromise on performance. It supports trickling impregnation processes and can handle rotors and stators with diameters up to 550 mm and lengths up to 390 mm.

Key features of the B8650 impregnation machine include:

Constant and controlled material flow: The machine ensures a steady and regulated flow of material, resulting in optimal insulation and flawless coating.
Optimal impregnation process: By maintaining precise control over the impregnation process, the B8650 delivers superior insulation quality.
Full flexible process: By an enhanced configurable SW, and its great design, it will be possible configure several different impregnation process, heating and dispensing profiles.
Increased durability: Components treated with the B8650 benefit from enhanced durability and resistance to environmental stressors.
Clean and efficient impregnation: With the trickle varnishing impregnation, the resin is applied directly to the winding. This process is more clean and more efficient – the stator/rotor and the machine do not have to be cleaned.

Sealing Cell Module Controllers Using the CIPG Process

Battery sensors play a crucial role in controlling and managing the performance and safety of electric vehicle batteries. They monitor parameters such as temperature, voltage, and current, and report this information to the battery management system (BMS), which controls and monitors the battery's charging and discharging processes.
