The CRCA steel motor stamping Type 200 is a precision lamination used to build electric-motor cores. “Type 200” denotes a specific frame/size in the motor-stamping range, blanked from electrical-grade CRCA steel for consistent magnetic performance.
What makes it a good motor core
Motor efficiency is decided largely by the core, so the Type 200 stamping is pressed to hold accurate slots, uniform thickness and a controlled burr. Stacked into a stator or rotor, these laminations keep iron losses low and torque smooth.

CRCA Steel Motor Stamping Type 200 — overview
"Type 200" denotes a motor lamination family built around a 200 mm class outer diameter. These larger stampings are used in higher-output single-phase and three-phase induction motors, agricultural and industrial pump sets, compressors and machine-tool drives. The bigger diameter carries more copper and iron, so slot design, tolerance and stack integrity become even more important to efficiency.
Technical specifications (typical)
| Parameter | Typical range |
|---|---|
| Outer diameter | ~200 mm class |
| Material | CRCA; CRNGO silicon steel for higher efficiency |
| Thickness | 0.50 mm / 0.65 mm |
| Stator slots | 24 / 36 / 48 (design dependent) |
| Stacking | Interlock, weld, rivet or cleat |
| Tolerance | ± 0.05 mm; controlled air-gap concentricity |
Common applications
- Three-phase induction motors (2–10 HP class)
- Agricultural and industrial pump motors
- Compressors and blowers
- Machine-tool and conveyor drives
Getting efficiency right at 200 DIA
At this size, iron loss and air-gap uniformity strongly affect running cost. We control burr height and stack factor so the assembled core is tight and the rotor/stator air gap stays concentric. For motors that must meet higher energy-efficiency (IE) classes, we recommend CRNGO silicon steel over plain CRCA to reduce core loss; for general-purpose duty, CRCA offers the best value.
Manufacturing and finishing
Type 200 laminations are produced on high-tonnage presses with hardened dies, then stacked to your chosen method. We can supply rotor and stator laminations as a matched set, loose or as finished cores, with your keyway, vent holes and slot profile.
