Abstract
The utility model relates to a hub motor, particularly to a DC brushless wheel type hub motor. The hub motor comprises a motor stator, a motor rotor, an end cover, a stator shaft and a bearing, wherein, the motor rotor is an integrated hub-type rotor; the outside of the rotor is in the shape of a hub, on which a tire can be directly installed; the outside hub and an inside magnetic circuit iron ring are cast as a whole body; permanent magnets are stuck to the inner side of the magnetic circuit iron ring in sequence; a hole is formed on the outside hub and used for the installation of an inflating valve; a stator shaft hole is formed in the middle of the end cover; and the end cover is fixed to the motor rotor through a bolt. In the utility model, the motor rotor and the hub are cast as a whole body, so that the wheel space is fully utilized, the diameter of the motor rotor is increased, and the motor power can be increased; except for the stator shaft hole, the whole end cover is installed on two sides of the motor rotor, so that not only the strength is increased and the motor is suitable for various vehicles, but also the end cover is more solid and durable. In addition, the surface area of the end cover is increased, thereby being conducive to heat dissipation, and reducing the possibility of burning down of the motor due to overheating.
Description
Technical field
The utility model relates to a kind of wheel hub motor, especially a kind of brush DC wheel formula wheel hub motor.
Background technology
At present, reach its maturity as the electric bicycle that drives energy with electric energy, its drive motors technology has been made significant headway especially, but under the prior art, defectives such as the motor ubiquity speed of producing is low, moment of torsion is little, efficient is low, high-power, high pulling torque, high-speed electric expreess locomotive relative volume are bigger, in use produce a large amount of heats, electric machine temperature rise is fast, motor is burnt in heat radiation slowly, easily, for the battery-operated motor cycle that high-power requirement is arranged, electric automobile, be difficult to meet the demands, restricted to a certain extent at a high speed, the development of the high-power electric vehicles.
The utility model content
The utility model technical issues that need to address provide a kind of high-power, high pulling torque, high speed brush DC wheel formula wheel hub motor.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of brush DC wheel formula wheel hub motor, comprise motor stator, rotor, end cap, stator axis, bearing, described rotor is the integrated rotor of hub-type, its outside wheel hub shape for tire can directly be installed, outside wheel hub and inboard magnetic circuit iron ring cast solid are pasted permanent magnet successively in magnetic circuit iron ring inboard, have the hole that is used to install valve cock on the outboard wheel hub, has the stator axis axis hole in the middle of the described end cap, and by screw on rotor.
Wheel hub bottom first step up is located in the hole that is used to install valve cock, to the distance of the integrated centre of rotor of this hub-type radius greater than end cap.
Described end cap maximum outside diameter is greater than magnetic circuit iron ring external diameter, its side is provided with the reinforcement radiating ribs, on the magnetic circuit iron ring of rotor, described first step height H is greater than 14mm by screw for end cap, and described rotor wheel hub section thickness T is between 6mm-40mm.
Adopt the beneficial effect that technique scheme produced to be: by rotor and wheel hub are cast as one, made full use of wheel space, increased the rotor diameter, that power of motor can be done is bigger, be applied to electric automobile, transmission mechanism and energy loss have also been reduced, radiating effect is also better, end cap adopts the full end cap except that the stator axis hole to be installed in the rotor both sides, has not only increased intensity, makes motor be suitable for various vehicles, and it is more durable, end cover surface is long-pending simultaneously increases, and is beneficial to heat radiation, greatly reduces motor because of overheated possibility of burning.
