[implementing and effect]
The advantage of compound many combination three-dimensional permanent magnet motors of dish and the contrast of traditional pillar magneto is applied on the urban bus;
Tradition pillar magneto needs the above voltage of 600V.
The compound many combination three-dimensional permanent magnet motors of dish only need 300V voltage.
Traditional pillar magneto needs 360V voltage on intermediate-size car.
The compound many combination three-dimensional permanent magnet motors of dish only need 115V voltage.
Calculate with 10 meters urban bus, its peak torque is 460Nm, meet its required torque requirement, and traditional pillar magneto should just can output to 460Nm at 600V voltage 200KW.Tradition pillar magneto required electric current when max. output torque is 2.5 times of electric currents of permanent rotating speed moment of torsion output.Electric current was 400A when the permanent rotating speed moment of torsion of 200KW/600V voltage was exported, and the electric current during peak torque output is 1000A.So 600V voltage is to discharge for the excessive big at double electric current of protecting storage battery.So in order to meet above functional requirement; The volume of its motor itself should be about 1 meter * 1.5 meters; The huge of machine volume need be done very big adjustment in the structure of function aspect supporting; And make the cost of its allomeric function provide greatly, and the above high-tension electricity of 600V needs a large amount of high voltage generating station of construction supporting with it on urban applications, makes the investment of whole project also will improve greatly.
The compound many combination three-dimensional permanent magnet motors of dish are exactly three dish-shaped stators with one and half combinations, and single face rotor of a two-sided rotor is formed.Adopt three motor coil winding units on each motor dish stator unit; (1 * 3 * 3=9) its gross output is 90KW to each 10KW of motor coil winding unit; Each electric motor units output torque 200Nm (200 * 3)=600Nm; The required electric current of each 10KW/300V of motor coil winding unit voltage is 33A, the complete machine electric current of 33 * 3=99A * 3=300A.
The application of high-tension electricity mainly is to improve the efficiency of motor ratio.
It is the complete machine power to 200KW that tradition pillar magneto adopts the voltage of 600V.
It is to have surpassed 10: 1 ratio to 9 the 10KW power (complete machine power is 90KW) and the voltage of traditional pillar motor that the compound many combination three-dimensional permanent magnet motors of dish adopt the voltage of 300V.At the moment of torsion of low rate start high pulling torque output 2 times of traditional pillar motor.
Tradition pillar magneto electric current when car load starts is that 2.5 times of electric currents of complete machine rated power could start.
The electric current of the compound many combination three-dimensional permanent magnet motors of dish when car load starts only needs the electric current of raising 20% on the basis of the required electric current of complete machine rated power just can start fast at short notice whole, shortened the discharge time of big current start speed-raising.Particularly when reaching certain speed, can make the power of complete machine and energy obtain more reasonably bringing into play, each electric motor units is guaranteed on the operating state of best efficiency point through the energising of closing a group (three units in a unit) automatically of controller.Like three unit motors when the best efficiency point operating state is gone; The electric current that uses of its complete machine is 99A * 3=300A; And the electric current when closing a unit has only 200A; This is that traditional pillar motor is beyond one's reach, because of equally at the power that is traditional pillar magneto output with the compound many combination magnetoes of the electric current dish that uses 200A under the voltage status, moment of torsion more than 2 times.
The compound many combination three-dimensional permanent magnet motors of dish do not have that excitatory steel consumption, efficient are higher, power factor and power density is big, volume is little; Adopt the vector converter speed setting controller to match simultaneously; Make the compound many combination three-dimensional permanent magnet motors of dish under efficient, energy-conservation this epochal topic, have pioneering and contribution novelty.
Though the present invention discloses as above with preferred embodiment; Right its be not to be used for limiting the present invention, anyly have the knack of this art, in spirit that does not break away from the present invention and scope; When can doing a little change, so the present invention's protection range is as the criterion when looking the patent protection scope person of defining.In addition, arbitrary embodiment of the present invention or claim must not reached whole purposes or advantage or the characteristics that the present invention discloses.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not the rights protection scope that is used for limiting the present invention.
