Description
Technical field
The utility model relates to motor device technical field, is specifically related to a kind of composite fabricated rotor of magneto.
Background technology
Motor refers to a kind of calutron realizing electric energy conversion according to the law of electromagnetic induction or transmit.Its Main Function produces driving torque, through being usually used in the power source of electrical appliance or various machinery.Permagnetic synchronous motor (hereinafter referred to as magneto) particularly adopts the magneto of rare earth material permanent magnet to have the advantages such as loss is few, efficiency is high, power savings is obvious, its structure is comparatively simple, and eliminate the collector ring and brush that easily go wrong, improve motor reliability of operation; Again because of without the need to exciting current, there is no excitation loss, also improve efficiency and the power density of motor.
Usually, rotor comprises iron core and axle, and the rotor of magneto is also containing magnet steel, the magnet steel mounting means of existing permanent magnet machine rotor has two kinds: directly surface-mount type and be press-fitted fastening-type, the shortcoming of direct surface-mount type is that magnet steel easily comes off, and fragile motor causes the accident under high speed centrifugation power, and need gluing when mounting magnetic steel, installation process wastes time and energy; The shortcoming being press-fitted fastening-type can adsorb iron mandrel because magnet steel is magnetic, and causes and be not easily press-fitted, easily damage workman, and will perforate could fastening magnet steel on magnet steel, has a strong impact on magnet steel intensity, and Long-Time Service can make magnet steel ftracture to throw away and cause the accident.
Summary of the invention
The purpose of this utility model is to solve prior art Problems existing, and provides a kind of composite fabricated rotor of magneto, simple and practical, mounting magnetic steel is time saving and energy saving, the bulk strength of magnet steel can be ensured and fastness is installed, can not come off and cause the accident, can be suitable for running up.
The technical solution adopted in the utility model is: a kind of composite fabricated rotor of magneto, comprise iron mandrel 1, two and two or more magnetic steel component 2 and balance back-up ring 3, magnetic steel component 2 is connected with iron mandrel 1, balance back-up ring 3 is arranged on the two ends of iron mandrel 1, the cylindrical of described iron mandrel 1 is provided with installation base 11, magnetic steel component 2 comprises mounting bar 21, magnetic steel ingot 22 and backplate 23, magnetic steel ingot 22 is arranged on the both sides of mounting bar 21, backplate 23 is arranged on the outside of magnetic steel ingot 22, mounting bar 21 is provided with groove 24 and elongated slot 25 are installed, groove 24 is installed be enclosed within installation base 11.
Described backplate 23 while be inserted in elongated slot 25, material is non-magnet_conductible material.
