Core offering

Proto Lam LLC manufactures custom prototype and short-run motor laminations for electric motors, generators, and electromagnetic equipment. The company produces stator and rotor laminations from cold rolled steel, silicon steel, nickel alloys, and cobalt alloys using in-house EDM and toolmaking capabilities, with sizes ranging from under 0.375 inch to 36 inches in diameter.

Product overview

Proto Lam LLC is a motor lamination manufacturing company specializing in prototype and short run production. The company offers four core lamination material products: Cold Rolled Motor Lamination Steel (CRMLS) as the lowest-cost option, Silicon Steel (Electrical Steel) in various grades for motion control applications, Nickel Alloys (49% and 80% Ni) for high-permeability applications like synchros and resolvers, and Cobalt Alloys (Hiperco/Vanadium Permendur) for highest flux density applications. The company provides engineering assistance during design phases and offers annealing services through qualified vendors to achieve optimum magnetic performance for all materials.

Products and services

• Cold Rolled Motor Lamination Steel (CRMLS) Lowest cost lamination material for volume motor applications, also called Cold Rolled Lamination Steel. Ease of stamping and low tool wear contribute to low finished part costs. Almost always annealed after stamping to develop optimum properties. Targeted at motor and electrical equipment manufacturers requiring cost-effective high-volume laminations.
• Silicon Steel (Electrical Steel) Low carbon steel alloyed with silicon to reduce eddy current losses in motor cores. Available in grades M19, M27, M36, M43 with varying core losses. Tailored for motion control products with grades called out by M-numbers indicating maximum core loss.
• Nickel Alloys High permeability alloys available in 49% Ni and 80% Ni compositions for low core losses at low to moderate inductions. Ideal for motors, synchros and resolvers. Requires careful annealing at over 2000°F with special atmosphere handling.
• Cobalt Alloys Hiperco or Vanadium Permendur laminations for highest possible flux density without saturation (22-23 kG saturation). Used in airborne and weight-sensitive applications. Requires precise annealing with controlled cooling rates in dry hydrogen atmosphere.

Emerging players

• American Industrial Company: American Industrial Company provides motor lamination stamping and related component manufacturing serving similar motor OEM and electromagnetic equipment customers in the US. It is comparable as a smaller US-based lamination manufacturer competing for short-run and prototype business.

Regional players

• Precision Micro: Precision Micro is a European (UK-based) specialist in photo-etched and precision metal components serving motor and electromagnetic applications. It is comparable as a niche supplier to motor designers with strong engineering and material breadth, though it primarily serves European customers rather than the US market.

Direct peers

• Brown-Pacific: Brown-Pacific is a custom metal stamper providing prototype through production runs, including precision electrical and motor-related components, with in-house toolmaking. It competes with Proto Lam for prototype motor and electromagnetic component orders.
• CJK Manufacturing: CJK Manufacturing offers prototype and production metal stamping with in-house tooling, EDM, and engineering support. It targets similar B2B customers needing quick-turn, low-volume precision stampings in a comparable size range to Proto Lam.
• Lestercast: Lestercast is a UK-based specialist in motor and transformer laminations, offering both prototype and production volumes across a wide range of electrical steels and nickel/cobalt alloys. It is highly comparable to Proto Lam in materials, customer base (motor designers), and prototype-to-volume service.
• Wingard & Company: Wingard & Company provides prototype and short-run metal stamping with in-house tool and die capabilities, similar in business model and customer profile to Proto Lam. While broader in product scope (not exclusively motor laminations), it competes for the same prototype stamping budget.
• Sko-Die: Sko-Die specializes in prototype and short-run precision metal stamping with in-house die design and EDM toolroom capabilities, closely mirroring Proto Lam's low-volume, high-customization, design-partnership model.

Broad incumbents

• Tempel: Tempel is a large, established manufacturer of motor laminations and electrical steel cores for motors, transformers, and inductors. It is directly comparable as a motor lamination manufacturer but operates at significantly higher volume and scale than Proto Lam's prototype focus.
