Processing & Assembly

The finer details involved in the assemblies

At NEMA we have a number of in-house processes which are required for the finishing of motors and electro-mechanical assemblies we produce, allowing us to maintain full control of all these processes.

Balancing
To avoid mechanical failures and reduce vibration of rotor and armature assemblies, NEMA has the ability to statically or dynamically balance components. This is carried out using CEMB Hoffman CE20/TC and Schenck RIB electronic balancing machines. Weight range: 0.05 - 10kg Journal Diameters: 2 - 35mm

Impregnation
All our electrical windings are impregnated, to improve the structural integrity and heat conduction properties, by vacuum or pressure impregnation using polyester or skybond varnishes.

Vacuum and Potting Encapsulation
When improved environmental sealing is required we can encapsulate the electrical winding in our encapsulation facility, using various types of materials as required by our customers.

Painting
NEMA has a fully equipped paint spray facility to enable finishing of components, using high temperature epoxy paints and lacquers, wherever this is required.

Magnetising
NEMA has the ability magnetise rare earth magnets using capacitor discharge magnetising equipment. This enables the magnets to be magnetised before or after assembly to ensure correct pole alignment.
