Description
The present invention relates to the stepless speed regulation technology field of electromechanical, a kind of variable-frequency stepless speed-regulating motor with frequency converter and motor or frequency converter and planetary reduction gear motor combination one.
The stepless speed regulation transmission is meant under the effect of certain control, make the output shaft rotating speed of machine can be in two extreme value scopes the continually varying kind of drive.Therefore be widely used in: the machine that technological parameter is changeable, require rotating speed continually varying machine, in machine rotational speed on the line of coordinating production between the operation and the trial production of new products process in order to seek machine optimum speed or the like.The stepless speed regulation transmission mainly contains electromagnetic type and mechanical type two major types (also having a type is liquid-type).Because the efficient of electromagnetic type and mechanical stepless speed governing is very low, the reductor so must contact in actual use, its result constitutes: motor-electromagnetic speed control device-reductor and motor-two kinds of tandem types of mechanical stepless speed regulator-reductor.These two kinds of long types of tandem have occupied a big chunk space of matched host machine, obviously are least rational types.
Frequency conversion type stepless speed regulation type, it is to utilize to change the stepless speed regulation that frequency realizes output speed, it mainly is made of frequency converter, motor in series reductor, its type axial dimension is shorter by contrast, weight is also light, but the price of frequency converter is comparatively expensive, makes its application extensive not as mechanical type.
The object of the present invention is to provide a kind of variable-frequency stepless speed-regulating motor with frequency converter and motor or planetary reduction gear motor combination one.Illustrate a bit be exactly to open up a kind of new motor really, it not only can carry out work done but also can also be in the low regime work done in high velocity because new motor collection stepless speed regulation with slow down to all over the body.
Technical application scheme of the present invention: (one) disintegrates frequency converter by function after, be installed in the rational position of motor respectively: power model is contained within the deflection cone dish before the axial flow blower and the utmost point is beneficial to heat radiation; Cpu system is installed on the inner chamber of connection box for motor loam cake; The outer surface that speed governing operating system is installed on the connection box for motor loam cake is used for the stepless speed regulation at production line scene or is installed on matched host machine; Carry out closely control operation, save the frequency converter plastic casing, save the fin and the little axial flow blower of power model.
The invention has the advantages that collection stepless speed regulation, motor and reductor are one, the long series connection type of original motor-buncher-reductor is shortened greatly, not only reduced manufacturing cost, weight reduction, and matched host machine is greatly reduced, be convenient to main frame and install, matched host machine weight saving simultaneously, cost reduces.
