Meanwhile, the original complex mechanical control mechanism can be replaced with an electric control device, the structure is simple, and the technology is mature and reliable.
Description
Technical field
The present invention relates to the magnetic pole field of motor, especially a kind of main pole of high power DC electric machine.
Background technology
Have many boats and ships to adopt direct currents at present, thereby often to be equipped with powerful DC generator, the power source of DC generator be the diesel engine on the ship as drive current.Let generator begin to run well, at first need the main axis rotation of a motor drives diesel engine; When diesel engine entering stroke, after can turning round voluntarily, the main shaft of motor rotor and diesel engine breaks away from; The diesel engine main shaft is connected with alternator shaft again, drives DC generator work, for other equipment electric energy is provided by generator.In practical application, more than 1500kw, type is generally separately excited DC machine to the power of said generator usually, because this generator power is big, stabilization of speed, output current are steady; Said power of electric motor is generally 50 ~ 80kw, and type is generally series machine, because this motor start-up torque is big, control is simple, it is less to compare other electric motor starting electric currents.
For above-mentioned reasons, need in the cabin of boats and ships to arrange two motors that floor space is bigger, causes cabin space narrow, safeguard also inconvenient; From the operating time of two motors, motor and generator can not worked simultaneously in addition, thereby an actual idle state that is in of motor is always arranged, and service efficiency is not high; The rotor of diesel engine main shaft and motor needs mechanical device to come control connection and disengaging, complicated in mechanical structure in addition.
Summary of the invention
The applicant is according to spot ship is big with the generating set floor space, utilization rate of equipment and installations is not high, the problem of complicated in mechanical structure; A kind of excitation pole of high power DC electric machine is provided; Thereby can use a motor to accomplish the startup and the power supply of generating set; Reduce space hold, improve utilization rate of equipment and installations, can replace original complicated mechanical controlling organization with electrical control gear simultaneously, simple in structure, technology maturation is reliable.
Technical scheme of the present invention is following:
A kind of excitation pole of high power DC electric machine; Comprise main pole and commutating pole that stator yoke is inboard with being connected stator yoke; Said main pole is overrided to form by punching; Commutating coil is nested in the periphery of said commutating pole, is nested with series excitation coil and separate excitation coil in the groove of said main pole periphery, and said series excitation coil is in the different circuit loops with the separate excitation coil.
Its further technical scheme is: said series excitation coil and separate excitation coil be arranged stacked in the groove of said main pole periphery, and said series excitation coil is positioned near armature one side, and said separate excitation coil is positioned at the side near said yoke.
Beneficial effect of the present invention is following:
1, connect with armature coil when series excitation coil, motor can be used as the series excitation DC motor operation, has that the series-wound motor detent torque is big, control is simple, the starting current features of smaller; When the separate excitation coil is connected with electrical appliance or storage battery, motor can be used as DC generator operation in the tower, and power is big, stabilization of speed, output current characteristics stably;
2、。The present invention merges to two original motors on the motor, and institute takes up space and dwindles greatly; Also improved the service efficiency of motor;
3, through the incision in circuit of electrical control equipment control series excitation coil and separate excitation coil, cut out; Device structure, less optional equipment have been simplified; Further reduce space hold, compare the complicated mechanical releasing mechanism, the operation of electrical control equipment is more reliable;
When 4, using as generator, series excitation coil can also be connected in the circuit as required, plays the effect of stablizing output current.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
As shown in Figure 1; The present invention includes stator yoke 1 and the main pole 3 and the commutating pole 5 that are connected stator yoke 1 inboard; Main pole 3 is overrided to form by punching; Commutating coil 6 is nested in the periphery of commutating pole 5, is nested with series excitation coil 4 and separate excitation coil 2 in the groove of main pole 3 peripheries, and series excitation coil 4 is in the different circuit loops with separate excitation coil 2.
Of Fig. 2, during use, at first with C, the conducting of D point-to-point transmission, series excitation coil 4 is connected with the coil of armature 7, and this moment, motor used as series-wound motor.Armature 7 is the rotor of motor, is positioned at the stator yoke middle part, in Fig. 1, does not mark.Insert DC power supply at A, B point-to-point transmission, the coil of 4 pairs of armatures 7 of series excitation coil produces magnetomotive force, and armature 7 rotates, and drives the spindle operation of diesel engine.After diesel engine got into stroke, can ownly turn round, A, B and C, D were separated.Import exciting current between A, D then; Armature 7 rotates under diesel engine drives; Therefore can produce the magnetic field of rotation on the armature 7, the magnetic line of force in the said magnetic field of separate excitation coil 2 cuttings in the main pole 3 produces electric current in the separate excitation coil 2; This moment, motor used as generator, thereby can insert marine storage battery or other electrical appliances at E, F point-to-point transmission.If the rotating speed of exciting current between A, D or armature 7 occurs than great fluctuation process; Can cause the electric current of output in the separate excitation coil 2 to have than great fluctuation process; Can insert direct current this moment between B, C; In series excitation coil 4 places in circuit, the fluctuation of excitation field can be offset in the magnetic field that produces in the series excitation coil 4, plays the effect of burning voltage.
The rotating shaft of armature 7 keeps being connected with the main shaft of diesel engine all the time in the whole process, does not need to break away from, thereby does not also just need mechanical separation equipment, and is simple in structure; Originally need come to cooperate startup, the power supply of accomplishing generator, and only need a motor to get final product now, dwindle floor space greatly, and make the interior space of cabin increase, can make things convenient for workman's operation, also other equipment can be installed with two motors with diesel engine. Break-make between each tie point can be passed through electrical control equipments completion such as contactor, PLC simultaneously, and technology maturation is simple in structure, safeguards also more convenient.In addition, the present invention only improves the magnetic pole of original separately excited machine, does not change its primary structure, thereby transforms conveniently, and the cost of transformation is lower.
More than describing is to explanation of the present invention, is not limitation of the present invention, and institute of the present invention restricted portion is referring to claim.Under the situation of basic structure of the present invention, the present invention can do any type of modification.
