Product Description
Name: Disc motor stator teeth
Material: insulation iron powder
Processing technology: powder pressing molding
Use:n stator teeth are assembled to form a ring, which is used as an axial motor statoriron core.
Design is exquisite:The basic operation of the machine depends on the interaction between the permanent magnets of the rotor and the energized windings of the stator. However, even if the motor is not energized and no current flows through the windings, there is a magnetic attraction between the permanent magnets of the rotor and the ferromagnetic teeth of the stator. The magnetic attraction force changes according to the magnetic flux density or strength of the magnetic field. This change will cause the torque to be uneven, called"Cogging torque" or "torque ripple".At high speeds, it is usually filtered out by the inertia of the system, but at low speeds, torque ripple can cause unnecessary speed fluctuations, vibration and audible noise.
Traditionally,DiscMotor statorToothAn iron core usually manufactured by winding technology. Each specification of the core manufactured by winding technology requires a corresponding special tooling for production.DiscMotor statorToothIn the winding manufacturing process, it is generally necessary to use the way of winding while punching. However, the way of punching and winding processing has a certain degree of difficulty and low production efficiency.
Disc motor stator teeth usedSMC composite soft magnetic material processing technologyThe bottom plate, stator teeth and magnetic blocks can be manufactured separately and then assembledDiscMotor statorToothIt can reduce the difficulty of production and greatly improve production efficiency. In addition, there is no need for special winding equipment for product manufacturing, which is convenient and simple to manufacture. In addition, manufacturing equipment and tooling mold requirements are low. High precision parts, reliable structure.In the mold design process can be in the disc motor stator base plate slot, pressed out of the finished product effectively reduce the motor's"Cogging Torque"
