We supply custom 14-Pole Neodymium Magnet Rings (7 North / 7 South) as per your specifications. They are common magnetic components for high-torque density applications. Generally, standard ring magnets use binary pole counts (4, 8, 16). But 14-Pole magnets are the industry standard for 12S14P Brushless Motors (12-Slot Stator, 14-Pole Rotor). This specific magnetic geometry reduces cogging torque while maximizing thrust and efficiency. We can offer the precise polarity pattern required to drive your high-performance actuators. No matter you require a monolithic Bonded Ring for a small gimbal motor. Or a Sintered Segmented Assembly for a heavy-lift drone. The Engineering Logic: The “12S14P” Connection Why 14 Poles? The 14-pole rotor is rarely used for sensors; it is a Motor Topology choice. The Application: – Paired with a 12-Slot Stator (12 coils). The Benefit: – This combination creates a “Fractional Slot Concentrated Winding” motor. – In plain English, it produces High Torque at Low RPMs with very low vibration. Our Expertise: – We ensure the pole transitions are sharp and equally spaced (360∘/14=25.7∘ per pole). – This will you help maintain motor balance and efficiency. Construction Options: Ring vs. Segments A solid 14-pole sintered ring can be expensive to tool. You can consider alternatives if costs are important for your applications. 1. Bonded Neodymium Rings (Monolithic): Best For: Camera Gimbals, Small Fans, Lidar Motors. Pros: Seamless ring, excellent waveform, lower cost for high volume. Cons: Lower magnetic strength (not for heavy lifting). 2. Segmented Assembly (The “Rotor” Solution): Best For: Heavy-Lift Drones, Robotics, E-Skateboards. The Reality: Making a large solid sintered 14-pole ring is difficult. Our Solution: – We typically supply a “Matched Set” of 14 Arc Segments (7N / 7S). – Or glue them into a steel ring for you. – This allows you to use N52 or N45SH grades for maximum power (impossible with bonded rings). Magnetization Orientation Radial (Inner Rotor): Poles are on the OD. (The motor spins inside the stator). Radial (Outer Rotor): Poles are on the ID. (The standard “Outrunner” motor for drones). Axial: Available upon request, but rare for 14-pole configurations. Surface Coatings Black Epoxy: The #1 choice for 14-pole motor magnets. – It withstands the heat inside a motor and bonds aggressively with structural adhesives. – This ensures the magnets don’t fly off at 10,000 RPM. Parylene: – For waterproof/submersible drone motors. Nickel: – Standard, but requires careful surface prep before gluing. Applications UAV / Drones: Propulsion motors (Outrunners). Camera Stabilizers: Gimbal motors (requiring smooth, cog-free rotation). Robotics: Joint actuators. Marine: Thrusters for ROVs (using epoxy-coated 14-pole arrays). Ordering Guide: What We Need To quote this, we need to know your “Motor Architecture”: 1). Dimensions: OD x ID x Thickness (or Length). 2). Configuration: Do you need a Solid Ring (Bonded/Sintered) or 14 Separate Arcs? 3). Grade: Do you need High-Temp resistance (e.g., 150°C)? 4). Application: “Is this for a 12-Slot Stator?” (This confirms the application).
