The CRCA steel electrical stamping 110 DIA is a round lamination, 110 mm in diameter, blanked from cold-rolled close-annealed (CRCA) steel and stacked to form the core of an electric motor. The “110 DIA” simply refers to the outer diameter — a common size for mid-range single-phase and small three-phase motor stators.
Why CRCA steel?
CRCA is prized for electrical stampings because it offers a smooth, clean surface, consistent thickness and good magnetic permeability. Those properties keep eddy-current and hysteresis losses low, so a motor built on CRCA laminations runs cooler and more efficiently.
Typical specification
- Diameter: 110 mm (110 DIA)
- Material: electrical-grade CRCA steel
- Shape: round, slotted stator/rotor profile
- Application: electric-motor cores
- Edge: burr-controlled for clean stacking
Getting the right stamping
Slot geometry, thickness and burr height all matter — which is why the 110 DIA stamping should come from a press shop that controls them batch to batch.

CRCA Steel Electrical Stamping 110 DIA — a closer look
A "110 DIA" electrical stamping is a stator or rotor lamination with a 110 mm outer diameter. It is one of the most widely used fractional-horsepower sizes in India, found in single-phase induction motors, submersible and monoblock pump motors, exhaust and fan motors, and light industrial drives. At Shree Balaji Electrical & Stamping we have blanked, notched and stacked 110 DIA laminations since 2007 under an ISO 9001 quality system.
Technical specifications (typical)
| Parameter | Typical range |
|---|---|
| Outer diameter (OD) | 110 mm |
| Material | CRCA (cold-rolled close-annealed) / CRNGO silicon steel on request |
| Sheet thickness | 0.50 mm / 0.65 mm (0.35 mm for low-loss grades) |
| Stator slots | 24 / 36 (application dependent) |
| Burr height | ≤ 0.03 mm (tight burr control for a clean stack) |
| Stacking | Interlock, cleat, weld or rivet |
| Tolerance | ± 0.05 mm on critical dimensions |
Where 110 DIA stampings are used
- Single-phase induction motors (0.5–1.5 HP)
- Submersible and self-priming pump motors
- Air-cooler, exhaust and table-fan motors
- Power tools and small industrial drives
Why CRCA for a 110 DIA lamination
CRCA gives an excellent surface finish, good flatness and consistent thickness at a lower cost than fully processed silicon steel — ideal for cost-sensitive, high-volume motor programmes where the magnetic duty is moderate. For motors that must run cooler and more efficiently, we also supply the same 110 DIA geometry in CRNGO silicon steel, which lowers core (iron) loss. We help you pick the grade that matches your efficiency target and price point.
How we manufacture and control quality
Each lamination is produced on a precision press using a hardened progressive or compound die, then checked for burr height, slot geometry and stack factor. Tight burr control keeps the stack tight and the air gap uniform, which directly protects motor efficiency and noise levels. Stacks can be supplied loose, interlocked, cleated, riveted or welded to your drawing.
