Description

Motor apparatus

[technical field]

The utility model relates to a kind of motor apparatus, particularly relates to a kind of utilization and is located at the silicon steel sheet that coil on the plate body and multi-disc stack together and produces energization excitation, and then drive the motor apparatus of rotation.

[background technology]

As shown in Figure 1, 2, the stator apparatus 1 of general motor is arranged on the shell 21 and can drives an impeller 22 and rotates, this shell 21 has a central siphon 211, this impeller 22 is hubbed on this central siphon 211, this impeller 22 has the blade 222 that a wheel hub 221, multi-disc extend from these wheel hub 221 outer peripheral faces, and a magnet ring 223 that is located on these wheel hub 221 inner peripheral surfaces, and this stator apparatus 1 is to be sheathed on this central siphon 211, is used to drive this impeller 22 rotations.

This stator apparatus 1 comprises an insulating base 11, this insulating base 11 has a leg 111, and four spaces and this leg 111 outward extending polar arm framves 112 certainly, and this stator apparatus 1 comprises that more multi-disc is arranged at the silicon steel sheet 12 on the polar arm frame 112 of this insulating base 11, four groups of coil groups 13 that are wound in respectively on the described polar arm frame 112 and a circuit board 14 that is electrically connected described induction coil 13.

According to above-mentioned structure, after this circuit board 14 is via extraneous power supply energising running, described silicon steel sheet 12 and coil groups 13 energization excitations, then the magnet ring 223 with this impeller 22 produces induction, wherein, be wrapped in coil groups 13 on the polar arm frame 112 by switching in each, make the silicon steel sheet 12 on the described polar arm frame 112 produce magnetic fields and form the magnetic force mutual exclusions, and then this magnet ring 223 is rotated with this magnet ring 223.

Because this insulating base 11 has four polar arm framves 112 for coil groups 13 windings, therefore after energising, make described silicon steel sheet 12 produce four magnetic poles of responding to this magnet ring 223, when number of magnetic poles is got over for a long time, the magnetic line of force that is produced is also many more, mean that the magnetic force that drives these magnet ring 223 rotations is also just big more, but must adopt identical number of turns circumvolution on polar arm frame 112 and produce huger volume for fear of described coil groups 13, thereby the leg 111 that causes this insulating base 11 is not enough to extend other polar arm frame 112 again, the number of magnetic poles of this stator apparatus 1 is limited to, and then the rotating speed of motor can't effectively be promoted.
