Abstract
The utility model discloses a three-phase brushless permanent magnetic motor rotor. The three-phase brushless permanent magnetic motor rotor comprises a hollow cylindrical casing, wherein the casing is made of magnetic conductive metal, the casing is internally provided with an annular magnet formed by one body molding, and the annular magnet is directly fixed at an inner wall of the casing through external pressure force. The casing is taken as the magnetic yoke of the annular magnet, so the number of motor fittings are reduced; the motor has a relatively small volume, moreover production technology is simplified; and cost is reduced.
Description
Technical field
The utility model relates to a kind of motor accessory, particularly a kind of rotor of three-phase brushless permanent-magnet motor.
Background technology
