FAQ: Electrical Stamping Technical Questions
Electrical stamping manufacturers produce precision-stamped silicon steel laminations that form the stator and rotor cores of motors. For drone and robot motors, these laminations are typically 0.20mm (or 0.15mm for racing) thick, with specific slot/pole configurations (9N12P, 12N14P, 12N8P, etc.), burr height < 0.03mm, and epoxy coating. These precision stampings minimize core loss, maximize efficiency, and ensure reliable performance at high RPM.
Specialist electrical stamping manufacturers understand the unique demands of drone motors: (1) high RPM operation requiring thin laminations (0.15–0.20mm), (2) strict weight constraints, (3) high efficiency requirements for extended flight times, (4) thermal management, and (5) low cogging torque for smooth control. Standard stamping manufacturers may not have the precision tooling or material expertise to meet these demanding requirements. Reenives specializes in these high-performance drone motor stampings.
For robot servo motors, 0.20mm laminations are typically optimal, offering: (1) low core loss for efficiency, (2) sufficient mechanical strength for servo applications, (3) good thermal performance, and (4) cost-effective manufacturing. For high-precision robot actuators operating at higher frequencies, 0.15mm laminations may be preferred. Reenives supports both thicknesses with custom tooling.
Burr height must be maintained below 0.03mm in electrical stampings 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 UAV and robotics applications where motor failure is unacceptable. Specialist manufacturers like Reenives maintain burr height < 0.03mm through precision progressive stamping dies.
Epoxy powder coating provides three critical functions for electrical stampings: (1) electrical insulation between laminations to minimize eddy currents and prevent interlaminar shorts, (2) corrosion resistance for operation in humid, outdoor, or industrial environments, and (3) thermal durability up to 180°C (Class H) to withstand heat generated during motor operation. The coating thickness (30–60µm) is optimized for tight slot geometries with dielectric strength exceeding 2.5 kV.
Reenives supports a wide range of slot/pole configurations for drone and robot motor stampings including: 9N12P (most common for FPV and racing drones), 12N14P (higher torque density for 5-inch+ drones), 12N8P (robot servo motors), 24N16P (industrial actuators), 24N22P (heavy-lift drones), and custom configurations for specialized applications. Private mould development is available for high-volume OEM projects with exclusive design rights.
When selecting an electrical stamping manufacturer for drone and robot motors, evaluate: (1) experience with high-frequency motor applications, (2) material grade capability (35PN210, 35PN250, etc.), (3) stamping precision—burr height, concentricity, and tolerances, (4) coating capability—epoxy insulation, (5) customization—ability to develop private moulds, (6) quality control—IEC testing and third-party verification, (7) production capacity—volume capability and on-time delivery, (8) technical support—engineering expertise, and (9) track record with UAV and robotics manufacturers.
