Vehicle, urban leisure vehicle are turned round, ideal rotating speed requirement is often not achieved using conventional brush-less motor, therefore, how to make brushless motor
Rotating speed raising is the current technical issues that need to address.
Utility model content
The purpose of this utility model is in view of the problems of the existing technology to provide a kind of Fast Installation and can improve to turn
The brushless motor of speed.
The technical solution of the utility model is：One kind can carry high-revolving brushless motor, including shell, stator, rotor
And shaft；The shell is clamped by upper shell and lower housing；The stator includes magnet ring；The magnet ring is by permeability magnetic material system
At being wound with coil on the magnet ring；The rotor includes magnet steel seat and the magnet steel in the groove of the magnet steel seat periphery, institute
It states magnet steel and constitutes closed magnetic circuit with the magnet ring and the coil；The shaft, magnet steel seat and magnet ring by center to outer ring successively
It is arranged, and is respectively positioned on the enclosure interior；Be equipped at the contact surface of the upper shell and lower housing the annular groove that is mutually clamped and
Annular convex platform, the upper shell are connected with lower housing by trip bolt.
Further, the upper shell and lower housing are internally provided with step, and the magnet ring is placed on the step.
Further, the trip bolt is located at the intersection of the shell and the magnet ring.
Further, the magnet ring upper edge has been arranged circumferentially several iron core slots, and the coil is wrapped in two iron
On cylinder between core slot.
Preferably, the magnet ring upper edge has been arranged circumferentially 12 iron core slots.
Further, each magnet steel and the cylinders contact.
Preferably, the magnet steel quantity is 10.
The utility model has the beneficial effects that：Upper shell described in brushless motor described in the utility model and lower housing phase
Mutually clamping, limits the relative horizontal displacement between upper shell and lower housing, then passes through screw limitation between the two relatively perpendicular
Straight displacement and circumferentially displaced, positioning is more accurate, easier for installation；Torque is set to reduce simultaneously, output rotating speed improves.
