Abstract
The invention provides a motor tandem connection structure, and belongs to the field of a drive device. The motor tandem connection structure comprises at least two motors, wherein the motors are in tandem connection with each other, and a rotor of a previous motor is fixedly connected with a stator of a subsequent motor. The motor tandem connection structure is specifically realized in the following way: the two motors are powered on, the rotor and the stator of each motor have a constant relative rotation speed; the rotor of the first motor is fixedly connected with the stator of the second motor, and the stator of the second motor is driven to rotate, so that the final rotation speed of the rotor of the second motor is equal to the sum of the rotation speed of the stator and the rotation speed of the rotor relative to the corresponding stator. By adopting the structure, the final output speed can be increased.
Description
Technical field
The present invention relates to drive unit field, in particular to a kind of motor series connection structure.
Background technology
Motor is a kind of modal drive unit, and current motor is all single running, and by the restriction of material and manufacturing process, the output speed of current single-motor can not be too high, can not meet the high-revolving demand of some occasion.
Summary of the invention
The invention provides a kind of motor series connection structure, be intended to solve the problem.
The present invention is achieved in that
A kind of motor series connection structure, comprise motor, described motor has two at least, and described motor serial connection, wherein the rotor of previous motor is fixedly connected with the stator of a rear motor.
Further, being fixedly connected with mode described in is Flange joint: the rotor of previous motor and the stator of a rear motor are connected with the ring flange matched respectively, and two ring flanges are fastened by bolts.
Further, the mode that is fixedly connected with described in is for welding.
Further, the mode that is fixedly connected with described in is that joint connects: there is the groove mated with motor rotor output one end of described joint, and the other end is provided with projection, and the stator of described motor has the depression of mating with described projection; The rotor of previous motor is connected by described joint with the stator of a rear motor.
Further, described motor series connection structure is connected with power supply by electric brush slip ring.
Motor series connection structure provided by the invention, specific implementation is such: switched on power by motor, and the rotor of each motor and stator have fixing relative rotation speed; The rotor of first motor drives the stator rotation of second motor fixing with it, therefore the rotating speed that the final rotating speed of second motor rotor equals its stator adds the rotating speed of upper rotor part relative stator, and the rotating speed namely equaling first motor rotor its stator relatively adds the speed of second motor rotor its stator relatively.By that analogy, the output speed of last motor equals the relative velocity sum of each motor rotor and stator.By such structure, improve final output speed.

Embodiment
Refer to Fig. 1 and Fig. 2, for the motor series connection structure that first embodiment of the invention provides, comprise two motors, the rotor 102 of first motor and the stator 103 of second motor are connected with ring flange 104, two ring flanges 104 matched respectively and are fastened by bolts.The dead in line of the rotor 102 of first motor and the stator 103 of second motor.Wherein second motor is connected with power supply by electric brush slip ring.
Due to second motor after being powered up, its stator and rotor are all rotating; And electric brush slip ring can be powered for the equipment rotated, therefore second motor adopts electric brush slip ring to be connected with power supply.
Open after being switched on power respectively by two motors, the rotor of each motor and stator have fixing relative rotation speed; The rotor 102 of first motor drives the stator 103 of second motor be fixedly connected with it to rotate, and the rotating speed that therefore the final rotating speed of second motor rotor equals its stator adds the rotating speed of upper rotor part relative stator.By such structure, improve final output speed.
Refer to Fig. 3, the motor series connection structure that second embodiment of the invention provides, comprise two motors, the rotor 102 of first motor and the stator 103 of second motor are by being welded and fixed.The dead in line of the rotor 102 of first motor and the stator 103 of second motor.
In a first embodiment, the rotor 102 of first motor and the stator 103 of second motor are fixed together by flange, this fixing means is relatively more firm, and the dead in line degree connecting the rotor 102 of rear first motor and the stator 103 of second motor is higher, and total is more stable.In a second embodiment, the rotor 102 of first motor and the stator 103 of second motor are fixed together by welding, and this fixing means is fairly simple, the cost-saving and time.
Refer to Fig. 4 and Fig. 5, the motor series connection structure that the third embodiment of the present invention provides comprises three motors and two joints 105, there is the groove 106 with motor rotor output form fit joint 105 one end, the other end has projection 107, motor stator has the depression of mating with projection 107, the rotor 102 of first motor is fixed by the stator 103 of joint 105 and second motor, and the rotor of second motor is fixed by the stator of joint 105 and the 3rd motor.The dead in line of all motors.
Connect former and later two motors by joint 105, it is more firm that this mode compares Flange joint, dead in line Du Genggao.In addition, this embodiment comprises three motors, improves final output speed further.
In actual production, can calculate the required motor number be connected in series according to the rotating speed of concrete demand and single-motor, being not limited to two or three motors serial connection, also can be a lot of.
Equally, Ben Mada series connection structure not only limits to electric field, also at other energy occasion, such as air motor, such as hydraulic motor, also can use the lifting that motor series connection structure provided by the invention reaches final output speed in these occasions.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
