Vent, Finger & Pressure Plate Assembly
As an ISO 9001:2015 Certified company, Laser Technologies delivers fully integrated turnkey manufacturing services to the motor and generator industry. We concentrate on delivering high quality, cost effective manufacturing solutions, which includes vent plate, finger plate, and pressure plate assembly.
Vent Plate Assembly
The vent plate is a common component in the motor and generator industry. Laser Technologies has the capability to manufacture different styles of vent plates:
- Spot Welded - We can use I-beam or solid bar, typically a cold roll steel or stainless steel per the customer specification. Our process entails spot welding fingers on thicker gauge backup laminations, then deburring and sanding the spot weld points to ensure there are no rough surfaces or material that could pierce or damage the insulation of the main body laminations once they are stacked into the assembly. Additionally, we can insulate vent laminations with Class F varnish.
- Riveted - The riveted vent lamination requires a process of embossing the backup vent plate lamination so that the mechanically attached fingers reside beneath the surface of the lamination to prevent any piercing of the insulation on the main lamination when they are stacked in the assembly. We typically laser cut the fingers, punch and boss the lamination, then attach the fingers to the backup lamination, and then press the fingers in so they lock in mechanically.
Finger Plate Assembly
The finger plate is a common component in the motor and generator industry. Finger plates are heavier duty constructed end plates which are used to help compress the core, holding the core together during the final assembly. We can assemble finger plates based on the customer-specified design and achieve this through:
- Spot Welding
- MIG or TIG Welding
- Machining
Pressure Plate Assembly
Pressure plates have a similar function to a finger plate, but they are more often used in large segmented motors or generators. These thick-gauged steel plates, typically 1" plus, are used to put pressure on the top and bottom of the core during final assembly.These pressure plates can be welded to the core assembly if the customer requirements dictate that necessity. Manufacturing processes we use to cut steel with this thickness is laser cutting, machining, or water jet cutting.
