Interlock Process Of Motor Core Laminated Stamping

The interlock process in the context of motor core laminated stampings refers to the specific method used to assemble individual laminations into the final motor core. Here’s a typical interlock process for motor core laminated stampings:

motor lamination interlocking process

Electrical steel raw material is precisely slit to the desired width and then loaded into the progressive stamping system. This involves processes like slitting, de-coiling, and flattening or straightening to ensure optimal material readiness.

The first step is to stamp the laminations out of a sheet of silicon steel. These laminations are typically thin and are stamped in a way that ensures their edges are sharp and precise.

The stamped laminations are then placed in a specific orientation to create an interlocked stack. The laminations are then auto stacked together to form the core of the motor. Interlocking points are commonly circular buckle point and rectangular buckle point. Progressive stamping employs interlocking processes.

We employ a CMM or 2D imager projector to check the electric motor lamination to ensure that it meets the required performance specifications.

Benefits Of Motor Core Laminations Assembly

Reduced Eddy Current Losses

By interlocking the laminations, the surface area through which eddy currents can flow is reduced, minimizing their effect on the motor's performance.

Lower Hysteresis Losses

By interlocking the motor core laminates, the realignment of magnetic domains is limited, which helps to reduce hysteresis losses.

Lower Noise and Vibration

Interlocking the laminations also helps to reduce noise and vibration in the motor, making it quieter and smoother in operation.

Improved Cooling

Interlocking the laminations creates tighter stacking, which allows for better heat dissipation to extend its lifespan.

Higher Efficiency

It can convert more of the input electrical energy into boosts energy efficiency, cutting operational costs.

Improved Torque and Power Density

Tighter stacking increases core density, boosting torque/power without size/weight increase.

How do I know if interlock motor laminations are the right choice for my motor?

In addition to the interlocking, we provide welding, self adhesive bonding, gluing bonding, riveting, cleating to bonded and stacked rotor and stator laminations of electric motors and generators. The lamination stacking process can improve motor magnetic properties.

Interlocking motor laminations are typically made of a type of 0.1 mm – 1 mm electrical steel, known as “silicon steel” or “silicon electrical steel.” This type of steel is chosen for its high magnetic properties, which allow it to efficiently conduct magnetic flux and minimize energy loss due to eddy currents.

In addition, we offer nickel alloys, cobalt alloys, and amorphous alloy materials to manufacture motor laminations.
