Abstract
The invention relates to an anti-lock circuit for a permanent magnet motor. The anti-lock circuit comprises a power supply and an IGBT module and is characterized in that: the power supply is connected with the IGBT module through a fuse wire; an output end of the IGBT module is connected with an input end of the permanent magnet motor through a release; the release is controlled by a release driving module; an input end of the release driving module is connected with a DSP processor; and the DSP processor is also connected with a current sensor which is used for detecting the power supply current of the permanent magnet motor. The anti-lock circuit for the permanent magnet motor is mainly applied to hybrid and all-electric vehicle driven permanent magnet motors, solves the problem that the personal injury is caused by overlarge dynamic braking current due to short circuit at the input end of the permanent magnet motor when the IGBT is driven to be broken down and the motor is positioned in the high-speed running process, and has high use value.
Description
Technical field
The present invention relates to a kind of anti-lock circuit for permanent magnet motor, particularly a kind of electric automobile anti-lock circuit for permanent magnet motor.
Background technology
Development along with existing electric energy technology, should be in energy conservation and environment protection, electric vehicle engineering is constantly ripe, yet in actual applications, the magneto of electric automobile is in and can occurs the short circuit of magneto input in the process of running up driving the breakdown and motor of IGBT, causes the damage to person accident thereby produce excessive dynamic brake electric current.
Summary of the invention
In view of the above problems, the purpose of this invention is to provide a kind of anti-lock circuit for permanent magnet motor, this circuit is mainly used in hybrid power and pure electric automobile drives magneto, solution is in and occurs the short circuit of permanent magnetic motor input in the process of running up and produce excessive dynamic brake electric current driving the breakdown and motor of IGBT, and causes the problem of damage to person.
The present invention realizes by the following technical solutions: a kind of anti-lock circuit for permanent magnet motor, comprise power supply and IGBT module, it is characterized in that: described power supply is connected with the IGBT module through a fuse, and the output of described IGBT module is connected with the input of magneto through release; Described release is controlled by the dropout driver module, and the input of described dropout driver module links to each other with dsp processor, and described dsp processor also is connected with the current sensor that is used to detect the magneto supply current.
The present invention carries out analyzing and processing by sensor acquisition curtage signal to dsp processor, protects motor thereby control is connected on the break-make of the release of motor side, modern design, and circuit is simple, has better use value.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present invention.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the invention provides a kind of anti-lock circuit for permanent magnet motor, comprise power supply and IGBT module, it is characterized in that: described power supply is connected with the IGBT module through a fuse, and the output of described IGBT module is connected with the input of magneto through release; Described release is controlled by the dropout driver module, and the input of described dropout driver module links to each other with dsp processor, and described dsp processor also is connected with the current sensor that is used to detect the magneto supply current.
In this preferred embodiment, described dsp processor also is connected with coaxial resolver or the position transducer of being located at the magneto coaxial position; Described release can be a three-phase, also can be two-phase.
Specifically, as shown in Figure 1, three-phase release 1 is in series with three-phase current sensor 2 and magneto 4, the supply current signal that current sensor 2 is gathered magneto is sent into dsp processor 8, and the space vector of calculating three-phase electricity flow valuve calculates braking moment with the rotor-position that dsp processor 8 is measured by coaxial resolver or position transducer 5.When the IGBT module short circuit; braking moment and super-high-current appear exceeding the quata; here be noted that; dsp processor described in present embodiment is connected with an independent current source respectively with the dropout driver module; like this; if the fuse of electrokinetic cell 3 damages, can thread off to control to the DSP power supply and by driving by described independent current source 7 disconnects three-phase release 1 when electric current is excessive, thus the protection magneto.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
