The thickness of lamination (which reduces eddy current loss) in electrical machine varies from:

(Select the closest range)

Electrical Machine core laminations:

• Electrical Machine core is generally made of thin strips called laminations to reduce eddy current loss.
• The thickness of the Electrical Machine core laminations is usually in the order of 0.5 mm to 5 mm.
• The thickness of silicon steel lamination is defined by varnish + silicon steel + varnish.
• Insulating material between laminations is required for electrical isolation, so as to reduce eddy current loss.
• The process of bunching of all laminations is called core staggering.
