What Are Stator Core Laminations?
Stator core laminations are thin sheets of electrical steel stamped into a slotted ring or segment shape, then stacked and secured to form the stationary magnetic core of a motor. Each lamination is coated with a thin insulation layer to limit eddy currents between layers — essential for efficient high-frequency operation.
In drone brushless motors and general BLDC motors, stator core laminations are the foundation of the electromagnetic circuit. Their material grade, thickness, stamping quality, and coating directly determine:
- Core loss & motor efficiency
- Heat generation & thermal performance
- Stacking factor & magnetic flux density
- Mechanical strength & vibration resistance
For motors operating at high RPM, CRNGO 0.2mm stator core laminations are essential to minimize eddy currents and maintain efficiency. CRNGO (Cold-Rolled Non-Grain-Oriented) steel offers uniform magnetic properties in all directions, making it the standard choice for motor stators.

How to Select the Right CRNGO 0.2mm Stator Core Laminations
Choosing the correct CRNGO 0.2mm stator core laminations for your BLDC motor involves several engineering decisions. Follow these steps:
- Determine Required Torque & RPM — Higher torque needs more stack length or larger diameter. High RPM demands thinner laminations and low-loss material.
- Select Slot/Pole Combination — Common drone motors use 12S/14P or 9S/6P. This affects cogging torque, winding factor, and efficiency.
- Choose Lamination Thickness — For high-frequency operation (e.g., 400Hz+), use 0.20 mm CRNGO laminations to reduce eddy current losses.
- Select CRNGO Grade — Lower-loss grades (e.g., 35WW200) reduce heat but cost more. Balance performance and budget.
- Decide on Assembly Method — Interlocked, bonded, or segmented laminations each have trade-offs in cost and performance.
- Consider Insulation & Coating — Epoxy powder coating is recommended for moisture, vibration, and chemical resistance.
- Verify Tolerances & Burr Height — Tight tolerances and minimal burrs ensure proper stacking and reduce vibration.
- Request Samples & Test — Reenives provides free samples for qualified projects. Test core loss, temperature rise, and mechanical fit.
FAQ — CRNGO 0.2mm Stator Core Lamination Parameters
Q1: Why use CRNGO 0.2mm laminations for high-RPM drone motors?
A: At high RPM, the magnetic field reverses rapidly, increasing eddy current losses. Thinner laminations — such as 0.2mm — significantly reduce these losses compared to standard 0.35mm or 0.50mm laminations. For drone motors operating above 10,000 RPM, CRNGO 0.2mm laminations help keep the motor cool, improve efficiency, and extend flight time. CRNGO steel also provides uniform magnetic properties in all directions, which is ideal for complex stator flux paths.

Q2: What burr height can you achieve with 0.2mm CRNGO stamping?
A: For 0.2mm CRNGO material, our high-speed progressive die stamping process typically achieves a burr height of ≤ 0.02 mm with optimized die clearance and regular maintenance. This ensures clean stacking, reduces inter-lamination shorts, and minimizes vibration. Tighter burr control can be achieved for specific applications upon request.

Q3: What is the typical core loss of your CRNGO 0.2mm stator core laminations?
A: Our 0.2mm CRNGO stator core laminations using 35WW200 silicon steel typically exhibit core loss ≤ 20 W/kg at 400Hz and 1 Tesla. This is lower than standard 0.35mm or 0.50mm laminations due to reduced eddy current losses. Actual core loss depends on material grade and operating frequency.

Q4: What CRNGO steel grades do you offer for 0.2mm stator core laminations?
A: We typically use CRNGO grades such as 35WW200 and 35WW230 for 0.2mm stator core laminations. These grades offer low core loss and uniform magnetic properties. The "35" indicates the nominal silicon content (3.5%), "WW" indicates non-oriented electrical steel, and "200/230" indicates the specific core loss grade. We can source other grades based on your performance and cost requirements.

Q5: Do you offer epoxy powder coating for CRNGO 0.2mm stator core laminations?
A: Yes. We use imported epoxy powder coating equipment to apply a uniform, pinhole-free insulation layer on individual laminations. This coating improves corrosion resistance, enhances wire adhesion, and protects against moisture — critical for agricultural and marine drones.

Q6: Can you develop custom CRNGO 0.2mm stator core laminations for my specific BLDC motor?
A: Absolutely. We support private mould development. Provide us with your required outer diameter, inner diameter, stack length, slot number, tooth profile, and CRNGO grade. Our R&D team will design and produce custom 0.2mm stator core laminations tailored to your motor. Tooling lead time is typically 15–25 days.
