Description

Plane inductor motor and motor-driven vehicle

A kind of motor of technical field and use the automobile of this kind motor.

The existing motor of technical background generally is that fixed stator case contains the rotatable rotor main shaft, and induced field each other is the face of cylinder.Its defective is that rotating torque is less relatively, can not be applicable to the mechanical device that needs the rotation of the motionless and housing of main shaft, can not on-line equipment in automotive wheel, drive wheels rotation and main shaft is motionless.

Traditional electric automobile just replaces I. C. engine with motor, still needs the intermediate transmission mechanism such as gearbox, universal joint could the drive wheels rotation, so the production cost height, energy consumption is big, fault is many, noise is big.

The utility model is under the inspiration of No. 99212528.6 " electromechanical integration compressors of air conditioner ", through putting into practice for many years and groping and conceive out, now manufactured experimently out the electric automobile model machine.

The summary of the invention the purpose of this utility model provides a kind of plane inductor motor and uses the motor-driven vehicle of this kind motor, accomplishes that the rotating torque of motor is bigger, is applicable to the mechanical device of the motionless and housing of main shaft rotation.The wheel of using its electric automobile need not intermediate transmission mechanism and realizes rotation, accomplishes that production cost is low, energy consumption is little, failure rate is low, noise is little.

The technical solution of the utility model is as follows: the stator core that four or more cross section is sector shape circularizes and is fixed on the stator core disk, is wound with stator exciting coil in each stator core, will form a plane induced field after the energising.The outlet of stator coil is by the central through hole external power supply of the hollow spindle that is solidified as a whole with the stator core disk.Cover end plate and bottom end plate that stator coil and stator core are shrouded at interior tubular hub are sleeved on the hollow spindle by ball bearing respectively, rotor core is housed on the cover end plate, be wound with rotor coil with the armature winding method in the rotor core, the aperture that the outlet of rotor coil is passed on the cover end plate is received on the copper commutator in the cover end plate outside, being fixed on has carbon brush and the activity of copper commutator to contact on the carbon brush holder on the hollow spindle, the lead on the carbon brush also passes through the central through hole external power supply of hollow spindle.The protective cover that hollow spindle one end and carbon brush holder are all covered is fixed on the cover end plate of tubular hub.Gapped between rotor core end plane and the stator core end face plane.

The motor-driven vehicle of using above-mentioned electronic device has following improvement: the hollow spindle of using the main shaft clamper end that is made of upper and lower clamping plate to clamp two wheels stretches out the outer part of tubular hub bottom end plate, upper and lower clamping plate are fastened on the spring damping steel plate below the automotive frame, on the tubular hub, be packed with pneumatic tire, the lead on stator coil outlet and the carbon brush is received on the power control that is positioned at driver's cabin.

The motor operation principle is as follows: stator coil energising back produces plane induced field, electrified wire cutting magnetic line on the rotor coil and rotating.In rotation process, the carbon brush that copper commutator conversion constantly contact is different in time changes the sense of current of rotor coil, thereby realizes that rotor coil is continuously toward same direction rotation, the cartridge type hub that promptly is loaded with rotor coil rotates around hollow spindle, and hollow spindle maintains static.

The motor-driven vehicle operation principle of using this motor is as follows: be embedded with airtyred bobbin hub rotation, promptly wheel rotates automatically, drives automobile and advances.Manipulation is installed in the power control in the driver's cabin, can control the speed of a motor vehicle by the size that changes electric current, can control by the sense of current that changes electric current and advance and fall back.

The characteristics of this kind motor are that rotating torque increases, and being applicable to needs the motionless and mechanical device of housing rotation of main shaft.The characteristics of using the motor-driven vehicle of this kind motor are to need not gearbox, Cardan shaft, chassis tooth bag differential mechanism, brake block device etc., the wheel rotation is self-driven, so manufacturing cost greatly reduces the energy resource consumption minimizing, fault is few, noise is little, keeps in repair easily and maintains.
