Abstract
The utility model relates to the technical field of motor manufacture and control and more specifically to a parallel connection DC brushless motor. The motor comprises a motor body and a control system. A stator winding of the motor body is composed of at least two varnished wires which are wound in parallel. The control system is composed of at least two power driving modules connected in parallel. One-to-one correspondence is formed between the varnished wires and the power driving modules. Each power driving module is formed by a power tube within a range from 80 to 100A. The parallel connection DC brushless motor shunts large current and large-power tubes are replaced by low-cost low-power tubes so that the control of the motor achieved. Therefore, cost is effectively decreased. In addition, damaged power tubes are convenient to replace; redundancy is increased; and reliable operation of a system is guaranteed.
Description
Technical field
The utility model relates to motor manufacture and control technology field, is specifically related to a kind of parallel connection direct brushless electric machine.
Background technology
The DC brushless motor power that electric automobile uses is now larger, and voltage is lower, has so just caused the electric current needing very large, and the control electric current needing is like this also very large.With rated voltage 60V, the motor that peak power is 12KW is example, and the electric current needing, more than 200A, is considered safe clearance, peak current etc., and the electric current of required power pipe is more than 800A.The power tube of this large electric current, price is high, and delivery cycle is long.Once power tube damages, motor just cannot turn round in time.
Summary of the invention
For addressing the above problem, the utility model provides a kind of parallel connection direct brushless electric machine, adopts low power tube to replace high power valve, reduces costs, and guarantees that motor runs well.
The technical solution adopted in the utility model is as follows: a kind of parallel connection direct brushless electric machine, comprise motor main body and control system, the stator winding of motor main body by least two enamelled wires and around, control system is composed in parallel by least two power driver modules, enamelled wire is corresponding one by one with power driver module, and described power driver module consists of the power tube within the scope of 80A-100A.At this, winding adopt many lines and around, can be by large current distributing, and corresponding every line controlled by a power driver module respectively, controls electric current and also shunts, and therefore can adopt little current power pipe to complete the control of heavy-duty motor, cost.While damaging if any indivedual power tubes, motor also can run well or reduce power running in short-term, improves the reliability of system.Power drive partly adopts modular, can be convenient for changing.
Further, for preventing the excessive damage causing of electric current, in described power driver module, be provided with overcurrent shearing device.
Preferably, the enamelled wire wire diameter that winding adopts is identical.
The utility model, by large current distributing, completes the control of motor with the high power valve of low power tube replacement cheaply, can effectively reduce costs, and the power tube that convenient timely replacing damages simultaneously, increase redundancy, guarantees system reliability service.
Accompanying drawing explanation
Fig. 1 is the system schematic of the utility model embodiment.
Embodiment
