Definitions

• Multipolar, axial flux motor especially for pump
• Subject of invention is multipolar, axial flux motor, especially for centrifugal pump, especially the segmented, axial flux synchronous motor, for three-phase voltage, controlled by frequency converter.
• Multipolar, axial flux motor especially for pump, according to invention, is characterized in that teeth of stator are located in circumferencial channel, beneficially in pump housing, containing magnetic ring with fixed magnets. Teeth of stator are fixed in cut outs in stator and have circumferencially located coils. Ring of stator creates return path. Whereas magnetic ring contains beneficially 56 magnets, beneficially in form of rectangular plates, fixed on return ring. Stator teeth have rectangular cut-outs for circumferencial cut-outs of stator ring. Beneficially, proportion of radius Rl of magnetic ring of stator to radius R2 of magnetic ring, is 0,955.
• Multipolar, axial flux motor thanks to integration of rotator magnet into pump rotator, in external place, possibly high torque is reached with lower number of magnets and coils, resulting in lower production cost of motor and pump.
• Introduction of big size radius of stator active ring has significantly increased the torque.
• Motor according to invention may be used for driving two types of devices like centrifugal compressors (centrifugal pumps) and piston pumps with magnetic coupler.
• Multipolar axial flux motor integrated with a pump, beneficially centrifugal one, containing housing 1, drives rotator of pump 8 shielded with cover 9.
• Stator teeth 4 are located in circumferencial channel 2, beneficially in pump housing 1, containing magnetic ring 3 with fixed magnets 31.
• Stator teeth 4 are fixed in circumferencial cut-outs 61 of stator ring 6 and have coils 5, located circumferencially.
• Stator ring 6 creates return path 7.
• Stator teeth 4 have rectangular cut-outs 41 for circumferencial cut-outs 61 of stator ring 6. Proportion of radius Rl of stator magnetic ring 6 to radius R2 of magnetic ring 3, is 0,955.
