What Is Stator Lamination?
Stator lamination is the precision-stacked assembly of thin silicon steel sheets that form the stationary magnetic core of an electric motor. Each lamination is stamped from electrical steel and stacked to create the stator—the component that carries copper windings and generates the rotating magnetic field essential for motor operation.
Why stator lamination is critical for agricultural drone motors:
- Eddy current reduction – Thin laminations (0.15–0.20mm) restrict eddy current flow, minimizing core loss that would otherwise generate heat
- High torque density – Optimized 24N22P configurations deliver the torque needed for heavy payloads
- Thermal management – Low core loss translates to cooler operation—critical for agricultural drones operating in hot climates
- Corrosion resistance – Epoxy coating protects against humidity, chemicals, and dust exposure in field conditions
ⓘ Stator lamination insight:"For agricultural drones operating in India's diverse climate conditions, stator lamination quality directly determines motor reliability and flight endurance. A 10% reduction in core loss can extend flight time by 8–12%."
Reenives manufactures precision stator laminations for agricultural drones using imported 0.2mm silicon steel, progressive stamping dies, and automated epoxy powder coating—ensuring optimal performance for demanding agricultural and heavy-lift UAV applications.

FAQ: Agricultural Drone Stator Lamination Technical Questions
Stator lamination is the precision-stacked assembly of thin silicon steel sheets that form the stationary magnetic core of an electric motor. For agricultural drone motors, it is critical because: (1) thin laminations (0.15–0.20mm) minimize eddy current losses, reducing heat generation and extending motor life, (2) optimized 24N22P configurations deliver the high torque needed for heavy payloads, and (3) low core loss translates directly to longer flight times—essential for covering large agricultural areas.
For agricultural spray drones carrying heavy payloads (spray tanks, pumps), the optimal stator lamination features: 0.20mm low-loss silicon steel, 24N22P slot/pole configuration, burr height < 0.03mm, epoxy coating (30–60µm, Class H 180°C), and stacking factor ≥ 97.5%. The 24N22P configuration delivers high torque with low cogging—ideal for heavy-lift crop spraying applications.
0.20mm laminations achieve core loss ≤ 8.5 W/kg at 400Hz—approximately 30% lower than conventional 0.35mm material. For agricultural drones operating in hot climates (such as India), this reduction in core loss translates to: (1) 10–15°C lower motor temperature, (2) 8–12% longer flight times, (3) extended motor life, and (4) the ability to carry heavier payloads without overheating. Thinner 0.15mm laminations provide even higher efficiency for premium applications.
24N22P (24-slot stator, 22-pole rotor) is the preferred configuration for agricultural heavy-lift drones. It offers: (1) high torque output for carrying spray tanks and payloads, (2) low cogging for smooth operation during precise spraying, (3) excellent heat dissipation for sustained field operation, and (4) proven reliability in demanding agricultural conditions.
Epoxy powder coating provides three critical functions for agricultural drone stator laminations: (1) electrical insulation between laminations to minimize eddy currents, (2) corrosion resistance for operation in humid, dusty, and chemical-exposed field conditions, and (3) thermal durability up to 180°C (Class H) to withstand the heat generated during heavy-lift operation. The coating thickness (30–60µm) is optimized with dielectric strength exceeding 2.5 kV.
Burr height is the raised edge left on stamped metal after the punching process. In agricultural drone stators, burr height must be maintained below 0.03mm because excessive burrs can: (1) damage enamel insulation on copper windings during assembly, causing short circuits, (2) create localized magnetic saturation points that reduce efficiency, (3) increase core loss through eddy current concentration, and (4) reduce motor reliability—critical for agricultural drones operating in remote field conditions. Reenives maintains burr height < 0.03mm through precision progressive stamping dies.
Yes. Reenives supports full customization of agricultural drone stator laminations including: stator outer diameter (12–80mm), lamination thickness (0.15–0.20mm), slot/pole configurations (24N22P, 12N14P, custom), stacking height, material grade, and epoxy coating specifications.
