Abstract
The utility model discloses a unilateral shaft automobile hub permanent-magnet brushless direct drive motor in the motor field. The direct drive motor comprises a main shaft; a stator carrier is installed on the main shaft; a stator is arranged on the outer periphery of the stator carrier and allows a coil to be wound; the left end of the main shaft is installed in a casing through a bearing; the left side of the casing is closed; a permanent magnet is arranged in the casing, corresponding to the outer periphery of the stator; yokes fixed on the inner wall of the casing are arranged on the outer periphery of the permanent magnet; an end cover is arranged on the right side of the casing; the main shaft sticks out of the end cover; the end cover is supported on the main shaft though the bearing; a wiring hole is formed on the main shaft and used for being communicated with an inner cavity of the casing; a lead wire of the coir passes through the wiring hole and extends out of the main shaft; and a hub fixing bolt is arranged at the closed end on the left side of the casing. When the direct drive motor is used, the hub fixing bolt is connected with an automobile hub, the main shaft is arranged on a chassis. When the motor operates, the main shaft and the stator remain stationary, the hub rotates to drive the automobile to drive. The utility model has the advantages of convenient installation of the hub, good heat dissipation, difficult demagnetization of the permanent magnet, large torque, high efficiency and suitability for electric automobiles.
Description
Technical field
The utility model relates to a kind of motor, particularly is used to drive the motor of electric automobile.
Background technology
Along with The development in society and economy; urban Environment Protection attracts great attention; the related industry that is the theme with environmental protection has become world development trends; because the relevant emission problem of city automobile becomes increasingly conspicuous; the urban development electric automobile is imperative; permanent magnetic brushless is called electronic commutation motor again; it need not to set up excitation field; need not commutator and brush, adopted long-pending energy of permanent magnet magnetic and automatically controlled phase commutation technology, make electric machine structure be simple and easy to produce; the speed adjustable range of broad and bigger low gear torque are arranged; and efficient wide ranges, characteristics such as long service life are widely adopted in the electric bicycle industry at present.The rotating shaft of this motor is stretched out from both sides, is unfavorable for the fixed car wheel hub, can't use on electric automobile as directly driving wheel hub motor.
The utility model content
The purpose of this utility model provides a kind of monolateral axle automotive hub brushless, permanently direct driving motor that overcomes the prior art defective, and motor can be fixed with automotive hub easily, and motor radiating is good, uses reliable.
The purpose of this utility model is achieved in that monolateral axle automotive hub brushless, permanently direct driving motor, comprise main shaft, stator support is installed on the main shaft, the stator support periphery is provided with the stator that installs around coil, the main shaft left end through Bearing Installation in housing, the sealing of housing left side, the corresponding permanent magnet that is provided with the stator periphery in the housing, the permanent magnet periphery is provided with yoke, and yoke is fixed on the inner walls, and the housing right side is provided with end cap, main shaft stretches out outside the end cap, end cap is bearing on the main shaft through bearing, and the external part of main shaft is provided with wiring hole and connects the housing inner chamber, and coil lead passes wiring hole and stretches out outside the main shaft; The blind end in housing left side is provided with the wheel hub set bolt.
When the utility model uses, be connected with automotive hub by the wheel hub set bolt, main shaft then is installed on the automobile chassis, and during machine operation, it is motionless that main shaft and stator keep, and permanent magnet, yoke, housing, end cap and wheel hub rotate together, the driving automobile motion.Compared with prior art, the utility model main shaft stretches out from an end, has made things convenient for housings close end fixed installation wheel hub, and permanent magnet is in the outside, and its heat radiation is good, is difficult for demagnetization, and this device torque is big, and the efficient height is fit to be used on the electric automobile.
For convenient braking, be fixed with the disc brake dish coaxial on the described end cap with main shaft.The disc brake dish can adopt the disc brake dish of existing automobile, and it is safe and reliable.When braking for reducing, the disc brake dish dispels the heat to end cap, is provided with heat insulating mattress between disc brake dish and end cap.
After avoiding damage of bearings, housing and main shaft break away from and cause accident, the bearing between described end cap and the main shaft is taper roll bearing.
