Black Epoxy Curved Sintered NdFeB Magnets for Drone Motor Features: Size: Custom Shape: Segment / arc / curve Coating: Black epoxy Grade: N52 Type: Rare Earth Permanent Magnets Composition: Neodymium Iron Boron Application: Drone Motor / Quadcopter motor The magnets in a motor play an important role in deciding how powerful a motor is going to be. Cheap motors will have weaker magnets and produce less thrust as compared to an expensive motor which will have more powerful magnets. Some higher-end motors even have curved magnets which are contoured to the shape of the rotor. Magnets used in brushless motors are graded based on the magnetic strength such as N52, N54 etc…, the higher the stronger the magnetic field produced by the magnets.
Moving on the next factor that comes into picture is the torque produced by the motor. Torque is the spinning force or the rotatory force that spins the propeller. It doesn’t matter much if you’re starting out. NdFeB Magnets for Drone Motor – Motor torque is affected by factors such as: 1. Stator size- bigger the stator higher the torque 2. Materials such as quality of magnets and copper windings in the rotor 3. Motor construction factors such as air gaps between stator and rotor. Torque produced by the motor significantly affects the performance of the quad. It also determines how the quad is going to feel for the inputs. Higher the torque produced by the motor, the more responsive the quad will perform.
