The motor comprises a rotor, coils, excitation systems and an outer shell, wherein the coils are fixedly connected with the rotor; central axes of the coils are parallel with a central axis of the rotor; the amount of the coils is 1-N; the excitation systems are arranged at two ends of the coils and are fixedly connected with the outer shell; and the amount of the excitation systems is 1-N pairs. The motor with the parallel platform effectively reduces the magnetic gap of the motor so as to improve the electrical efficiency of the motor, and improve the torque and the rotating speed of the motor in a limited space.
Description
Technical field
The present invention relates to a kind of motor, in particular, the invention relates to motor with parallel construction.
Background technology
At present, known motor, its coil centerline is vertical with the motor rotor axis, and permanent magnet is arranged on the rotor axis both sides.Advantage is simple in structure, and is easily manufactured, and shortcoming is owing to the bigger magnetic gap of existence, so electrical efficiency is lower, and general electrical efficiency is below 80%.Limited or make under the battery-powered situation in the motor space, how to improve the electrical efficiency of motor, be significant to improving product competitiveness.
Patent Office of the People's Republic of China discloses a CN1222002A document on July 7th, 1999, name is called permanent magnet motor, this invention provides a kind of handle to be configured in permanent magnet motor in the stator core that produces rotating magnetic field by the rotor core of permanent magnet magnetic poles, the coaxial joint all-in-one-piece of second iron core memeber rotor core that the electromagnetic torque of having buried permanent magnet in each magnetic pole underground is produced first iron core memeber of usefulness and do not have the reluctance torque of permanent magnet to produce usefulness, be used as rotor core, thus, can increase reluctance torque, and improve the efficient of motor.The shortcoming of this invention is that the overall structure of motor does not change, and the big magnetic gap problem that this structure itself is had is not resolved.
Summary of the invention
The invention solves the technical problem that the existing magnetic gap of motor original structure is big, electrical efficiency is lower, a kind of motor of parallel construction is provided, effectively reduced magnetic gap, thereby improved the efficient of motor, in limited space the torque of motor and rotating speed are improved, and have prolonged the service time of battery.
The technical solution adopted for the present invention to solve the technical problems is: the present invention includes rotor, coil, excitation system, shell; Described coil is fixedlyed connected with rotor, and coil central axe is parallel with the rotor center axle, and coil quantity is N; Described excitation system is arranged on the coil two ends, and fixedlys connected with shell, and the quantity of excitation system is that 1-N is right.Excitation system is arranged on the two ends of coil, coil can be in maximum magnitude cutting magnetic line, the gap of coil and excitation system can be done very for a short time, thereby has improved electrical efficiency, has improved motor torque; At peritrochanteric a plurality of coils being set, being connected to power supply according to different needs after with the coil serial or parallel connection, generally is to be connected to DC power supply, can obtain bigger moment of torsion like this.The quantity of excitation system can be selected between 1-N, and the pole orientation of each excitation system should be consistent.
As preferably, described excitation system is a permanent magnet.Excitation system is made by permanent magnet, and is simple in structure, easy to make.
As preferably, described excitation system is a hot-wire coil.Excitation system is made by hot-wire coil, and hot-wire coil can lead to direct current also can indirect current.
As preferably, described coil is fixedlyed connected with shell, and described excitation system is fixedlyed connected with rotor.When coil and shell linked together, wiring was more convenient.
As preferably, described a plurality of coils, a plurality of excitation system are provided with along the parallel axes stack of rotor, and the torque direction of each coil is identical.In the time of in motor can only be installed in elongated space, can increase motor torque so to greatest extent with coil and excitation system in the installation that in layer superposes of the axis direction of rotor.
As preferably, on described rotor, also be provided with carbon brush, described coil is connected on the power supply by carbon brush.When coil and rotor link together, coil as required serial or parallel connection after carbon brush be connected on the power supply.
As preferably, two or more coils evenly distribute at peritrochanteric; Described excitation system also evenly distributes at peritrochanteric.Can obtain best moving stablizing in the even distribution of peritrochanteric, motor is operated steadily.
The invention has the beneficial effects as follows: effectively reduced the motor magnetic gap, the electrical efficiency of motor is improved, in limited space, the moment of torsion of motor and rotating speed all have been improved.
