Stator End Lamination

Why motor stator lamination annealing process are needed for high performance bldc motors.

Stator end lamination. Performs custom stamping services for clients requiring high end specialty laminations built to extremely tight tolerances. The stator is the stationary part of a rotary system found in electric generators electric motors sirens mud motors or biological rotors energy flows through a stator to or from the rotating component of the system. High speed presses ranging from 100 tons to 800 tons. In an electric motor the stator provides a rotating magnetic field that drives the rotating armature.

So a heat treatment process was introduced to eliminate the stresses. Electric motor lamination stacks. Our stamping department is equipped with high speed presses with capacities of up to 250 tons. Rotor and stator lamination assemblies magnetic circuits for motor and generator.

As we know that the silicon steel sheet will cause some internal stresses during punching and stamping process. Example 2 the unit is a generator 133 mva 16 5 kv 40 poles that suffered a phase to ground short circuit fault near the end of the stator core. Annealing process is one of heat treatment process that eliminate the. Over 30 million press strokes per day allows output of over 300 tons finished magnetic circuits laminations each day.

Any air gaps between the turns the slot liners and the lamination core act also as insulators. In a generator the stator converts the rotating magnetic field to.
