Abstract
The utility model relates to integration series connection motor driver.Its Double shaft-extension end motor (1) the right rotating shaft is connected with shaft coupling (2) with between motor (4) rotating shaft, lead wire U, V, W correspondence of lead wire U, V, W of the wound stator of Double shaft-extension end motor (1) and the wound stator of motor (4) combines, after merging, correspondence is received on U, V, W binding post in terminal box, connected on lead-out terminal U, V, W of a frequency converter by cable correspondence, run by transducer drive.Structure is simple, improves motor speed, reduces moment of inertia, reduces noise, reduces vibration, reduced volume, the quality that alleviates, energy savings, raises the efficiency, reduces complete machine cost, reduces the features such as operating cost.
Description
Technical field
The utility model patent relates to machine field, especially integration series connection motor driver.
Background technology
1) existing heavy-duty motor, because power, torque are large, rotor external diameter is large, linear velocity is high, critical whirling speed is low, resonance frequency is low.During running, the amount of deflection of rotor is comparatively large with vibration, and motor cannot realize high rotating speed and run.Secondly the moment of inertia of standard electromotor is large, electric motor starting and dwell time long, modern fast-developing industrial requirements can not be met.
2) existing large power, electrically is confidential realizes the operation of high rotating speed, and the general motor that adopts adds step-up gear, oil lubrication system, shaft coupling, erecting bed metal plate etc.; Shorten motor starting time, general employing increases frequency inverter capacity; Shorten motor dwell time, general dynamic braking or the mechanical braking of adopting realizes.
Summary of the invention
For above-mentioned existing problems, the present invention seeks to employing two motor cascaded structure integralization series electric motor drive units.
The utility model adopts technical scheme, comprise Double shaft-extension end motor, shaft coupling, terminal box, motor, overhead guard, support, in aforesaid support upper shell, left side device has Double shaft-extension end motor, right side device has motor, overhead guard is had above support, be connected with shaft coupling between the right rotating shaft of its Double shaft-extension end motor and the rotating shaft of motor, the lead wire U having wound stator of Double shaft-extension end motor, V, the lead wire U having wound stator of W and motor, V, W correspondence combines, after merging, correspondence receives U in terminal box, V, on W binding post, the lead-out terminal U of a frequency converter is connected by cable correspondence, V, on W, run by transducer drive.
The utility model structure is simple, improves motor speed, reduces moment of inertia, reduces noise, reduces vibration, reduced volume, the quality that alleviates, energy savings, raises the efficiency, reduces complete machine cost, reduces the features such as operating cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, further illustrate the utility model.
Fig. 1 is the utility model structural representation.
In figure: 1-Double shaft-extension end motor, 2-shaft coupling, 3-terminal box, 4-motor, 5-overhead guard, 6-support.
Embodiment:
See Fig. 1, comprise Double shaft-extension end motor 1, shaft coupling 2, terminal box 3, motor 4, overhead guard 5, support 6, aforementioned
Support 6 upper shell in left side device has Double shaft-extension end motor 1, right side device has above motor 4, support overhead guard 5, be connected with shaft coupling 2 between rotating shaft with motor 4 rotating shaft on the right of its Double shaft-extension end motor 1, lead wire U, V, W correspondence of lead wire U, V, W of the wound stator of Double shaft-extension end motor 1 and the wound stator of motor 4 combines, after merging, correspondence is received on U, V, W binding post in terminal box, connected on lead-out terminal U, V, W of a frequency converter by cable correspondence, run by transducer drive.
Because the rotor inertia of integration series connection motor driver is little, external diameter is little, rotor linear velocity is low, motor speed is greatly improved; The rotor that inertia is little simultaneously, also shortens electric motor starting and dwell time;
Because integration series connection motor driver have employed two or more rotor; Have employed two covers or two and overlap above motor winding.Whole motor driver is equivalent to two or more motor of having connected.The power of output of integration series connection motor driver, torque and inertia just equal the summation of the power of two or more series electric motor, torque and inertia.
Claims (1)
1. an integration series connection motor driver, comprise Double shaft-extension end motor (1), shaft coupling (2), terminal box (3), motor (4), overhead guard (5), support (6), in aforesaid support 6 upper shell, left side device has Double shaft-extension end motor (1), right side device has motor (4), overhead guard (5) is had above support, its Double shaft-extension end motor (1) the right rotating shaft is connected with shaft coupling (2) with between motor (4) rotating shaft, the lead wire U of the wound stator of Double shaft-extension end motor (1), V, the lead wire U of the wound stator of W and motor (4), V, W correspondence combines, after merging, correspondence receives the U in terminal box, V, on W binding post, the lead-out terminal U of a frequency converter is connected by cable correspondence, V, on W, run by transducer drive.
