Abstract
The utility model discloses an electromechanical integrated permanent-magnet brushless DC electric machine, which is composed of a casing 1, a stator 2, a rotor 3, a wiring card 4, and a rotating shaft 5, wherein, a control plate (6) is directly fixed on a skeleton of the stator (2) which is positioned in the casing (1); the control plate (6) is connected with a connector (8) by a strand (7). The utility model has the advantages of energy saving low noise, small size, light weight, strong anti-interference ability, electromechanical integration, stable operation, reasonable structure, low cost, etc. The utility model can be widely used for speed changing systems of air conditioners with frequency conversion, household appliances thereof, apparatus, instrumentation, etc.
Description
The utility model relates to the improvement of motor, and specifically a kind of electromechanical permanent-magnet brushless DC electric machine is applicable in the speed change system of aspects such as convertible frequency air-conditioner and other household electrical appliance, instrument and meter.
At present in the speed change system of aspects such as convertible frequency air-conditioner and other household electrical appliance, instrument and meter, all adopt dc brushless motor, this dc brushless motor partly is made of housing, stator, rotor, wiring card etc., and its control board is provided with installation separately, is connected with inner the realization by lead.Though that this motor has is energy-conservation, noise is low, volume is little, advantage such as in light weight, but the control board control that sets up must be arranged, control board is the epoxy single sided board, rotor magnetic ring adopts ferrite bead, so there is dynamo-electric shortcoming of separating, simultaneously, the interference performance that also makes the wiring of anti-control line be produced is poor, noise height, job insecurity, reasonable structure are poor, and volume greatly, heavier, production cost is higher.
The purpose of this utility model be to provide a kind of not only have energy-conservation, noise is low, volume is little, advantage such as in light weight, but also have that antijamming capability is strong, the electromechanical permanent-magnet brushless DC electric machine of advantage such as working stability, dynamo-electric unification, production cost are lower.
The utility model is achieved in that this electromechanical permanent-magnet brushless DC electric machine partly is made of housing, stator, rotor, wiring card, rotation axis etc., the directly fixing control board of going up on the skeleton of its housing internal stator, and control board is connected with connector with wire harness.This motor is also implemented by following measure: the wiring board center of control board is provided with a circular hole, and the rotation axis of motor is inserted in the circular hole, and is fixed on the stator skeleton by the control board bayonet socket, has so just overcome the shortcoming that control board sets up.But because control board is located in the housing, taken segment space, added the heat radiation of motor heat that distributes in service and controller IC, made the rated power of motor be subjected to certain influence, the control board job stability also is affected.Be located at these problems that occur in the housing for improving control board, the control board of this electromechanical permanent magnetic brushless is the positive and negative two panels of epoxy, element is located at the two sides of plate, dwindled taking up room of control board to greatest extent, the magnet ring of rotor is to have the higher ferro-aluminum boron magnet ring of remanent magnetism, coercive force and magnetic energy product, and wire winding is also done corresponding improvement, and the leakage field copper loss is effectively descended, master chip is integrated (LB) 1976IC chip, outer attached circuit element Hall element 1H
