Abstract
The utility model relates to a motor and particularly relates to a brushless motor especially for an automobile radiator. The brushless motor for an automobile radiator comprises a front end closure, a middle end closure, and a stator and an external rotor which are arranged inside the end closures; the external rotor is fixed on a rotating shaft and a driver is arranged at the backside of the middle end closure; outgoing lines are arranged at the outside of the motor. The brushless motor is characterized in that a bearing is arranged at the end of the external rotor and a steel magnet is fixed at the inner side of the external rotor; the steel magnet is arranged between the external rotor and the stator; coils are embedded inside the stator. The brushless motor is small in volume, light in weight, high in utilization rate of the windings, high in efficiency, large in power and low in material consumption and is convenient and easy to control and install.
Description
Technical field
The utility model relates to a kind of motor, especially relates to a kind of brushless electric machine that is exclusively used in automobile radiators.
Background technology
As everyone knows, advantages such as electric bicycle, battery-operated motor cycle are emission-free with it, noiseless, safe, light, environmental protection just are being subjected to users' favor, and as the motor that drives usefulness, the research and development emphasis of many especially producers and research institution.Electric bicycle, the automobile-used motor of electric motorcycle mainly contain two kinds in the market: a kind of is brush direct current motor, and another kind is a dc brushless motor.Brush direct current motor brings noise, spark, radio interference, deadly defects such as the life-span is short, efficient is low, maintenance difficult thus because of adopting the structure of the mechanical commutation of brush; And brushless electric machine is to adopt the electronics commutation, and exchange drives, and therefore has advantages such as noise is little, high-energy-density, high reliability, high efficiency.So motor of electric motor car is gradually by brushless alternative brush motor.But existing electric vehicle brushless motor mostly adopts the teeth groove structure to reach radially magnetic circuit, exists the torque fluctuations that is caused by slot effect bigger, and winding utilization is the end of than, and volume is bigger.
Summary of the invention
The utility model mainly be big at the existing volume of prior art, weight is big, winding utilization is than the end, efficient is low, inconvenience is installed in control, power is little, consumptive material is big etc. technical problem, provides that a kind of volume is less, in light weight, winding utilization is higher, efficient is high, control simple installation, power is big, consumptive material is little automobile radiators brushless electric machine.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of automobile radiators brushless electric machine, comprise front end housing, middle end cap and the stator and the external rotor that are arranged on end cap inside, external rotor is fixed in the rotating shaft, middle end cap rear is provided with driver, motor is circumscribed with lead-out wire, it is characterized in that described external rotor end is provided with bearing, the external rotor inboard is fixed with magnet steel, magnet steel is arranged between external rotor and the stator, and described stator interior is embedded with coil.After the motor energized, Hall element detects the magnet steel position, and signal is delivered to master chip; Begin commutation work by the logical order driving tube; Energising forms magnetic field on the motor windings, and magnet steel and stator winding produce cutting magnetic off-line, start working thereby drive external rotor; It adopts advanced magnet steel technology and winding and the advanced high performance control technology different with other motors, has realized characteristics such as electronics and motor combine together, power is big, efficient height.
As preferably, described driver rear end is provided with back cover.It is simple in structure, the control simple installation, and save material.
As preferably, described in the end cap arranged outside mounting bracket is arranged, be provided with hold-down screw in the fixing hole on the described mounting bracket.It is rational in infrastructure, and is easy for installation, with the supporting external connection of various cars, than the copper aluminium of similar motor product saving more than 50%, for manufacturer has reduced cost.
As preferably, the length of described magnet steel is smaller or equal to the width of coil.During operating state, magnet steel and stator winding produce cutting magnetic off-line, start working thereby drive external rotor.
As preferably, described front end housing cross section is circular, and its diameter is 95mm-105mm.Its volume is less, and weight is lighter, and manufacturing cost is cheap relatively.
Therefore, the utlity model has characteristics such as volume is less, in light weight, winding utilization is higher, efficient is high, control simple installation, power is big, consumptive material is little.
