1. What are Brushless DC Electric Motor Stator Core Laminations? (Engineering Definition)

Brushless DC electric motor stator core laminations are thin stacked electrical steel sheets that form the stationary magnetic circuit of a BLDC motor. They channel magnetic flux from the windings to the rotor, directly determining torque density, efficiency, and thermal performance. For UAV drones, robotics, and industrial BLDC motors, high-quality laminations minimize eddy current losses at operating frequencies (200Hz–1kHz) and ensure precise dimensional tolerance (±0.02mm). Reenives manufactures laminations using imported stamping presses and proprietary epoxy coating technology.

2. Classification: Material Grades for BLDC Stator Laminations

Reenives offers tailored stator core solutions for high-speed UAV drone motors, precision robotics, and heavy-duty industrial BLDC motors.

Series	Material Grade	Thickness (mm)	Coating Type	Target BLDC Application
UAV Aero Series	20JNEH1200 / 27JNEH900	0.20 – 0.27	Epoxy green insulation (high dielectric)	FPV racing, long-endurance drones, eVTOL
Robotics Servo Series	35WW270 / 35PN210	0.35	Epoxy powder + anti-rust layer	Collaborative robots, AGV, servo motors
Industrial BLDC Series	50WW470 / 50CS1300	0.50	Phosphate + epoxy coating	Industrial brushless motors, e-scooters, power tools

Epoxy powder coating from imported German stamping lines ensures uniform thickness (20-30µm) and dielectric strength >1200V, drastically reducing eddy current losses in high-frequency BLDC applications.

5. Engineering Selection: 5-Step Guide for BLDC Motor Stator Laminations

Optimize your brushless DC motor design with these technical selection steps:

Determine operating frequency & speed range: UAV drones (300-800Hz) → 0.20–0.27mm laminations; industrial BLDC (<300Hz) → 0.35–0.50mm grades.
Select outer diameter and stack height: From 12mm micro motors to 220mm industrial frames. Custom stack heights available.
Specify slot/pole combination: 9N12P, 12N14P, 18S20P, or custom geometries. Reenives supports private mould development.
Choose coating & insulation: Epoxy powder coating for high humidity/dust environments (IP rating enhancement).
Request engineering samples & core loss report: Reenives delivers stator samples in 7–12 working days with full magnetic test documentation.

💡 Pro Tip: Our engineering team offers free electromagnetic FEA simulation for BLDC stator designs to validate torque density and iron loss before production.

6. FAQ – BLDC Stator Lamination Technical Deep Dive

❓ Q1: What core loss value can I expect for 0.20mm laminations at 600Hz for drone BLDC motors?

A: For our 0.20mm ultra-thin grade (20JNEH1200), core loss ≤ 12.8 W/kg @ 1.0T, 600Hz (Epstein test). This ensures minimal heat generation for high-RPM drone BLDC motors and improved thrust-to-weight ratio.

❓ Q2: How does epoxy powder coating improve BLDC motor efficiency?

A: Epoxy coating provides uniform dielectric barrier (20-30µm) between each lamination, eliminating micro-shorts and reducing eddy current losses by ~18–22% vs standard oxide coating. Results in cooler operation and higher continuous power output for BLDC motors.

❓ Q3: What stacking factor tolerance do you guarantee for 0.35mm industrial BLDC stacks?

A: Minimum stacking factor ≥97.3% (typical 97.5%) under 300 MPa clamping for 0.35mm grades. For 0.50mm industrial stacks, stacking factor ≥97.8% achievable, ensuring maximum magnetic flux conduction.
