Abstract
The utility model relates to a motor, in particular to a self-monitoring motor, comprising a motor and a control device which are electrically connected. The control device is connected to a power supply terminal of the motor after being connected with a power supply. One or more taps are drawn out from a loop of the motor and then are in feedback connection with the control device. The motor acquires electric energy from the control device. If the motor works abnormally, the control device can draw out one or more taps from the loop of the motor in order to acquire an abnormal voltage and a current signal for the purpose of judging the abnormal working state of the motor and performing if cutting off the motor to protect the motor efficiently in time. The utility model has the advantages that the motor is connected with the power supply by the control device, the external power supply will not be influenced, the voltage and the current monitoring signal of the inner loop of the motor can be real-time fed back to the control device, and the motor can be protected efficiently in time when abnormal state exists.
Description
Technical field
The utility model relates to a kind of motor, especially self-monitoring motor.
Background technology
The most unprotect measure of motor whether normally all with the abnormality continuous firing, causes burn-down of electric motor regardless of operating current, voltage easily.And the occupation mode that adopts morely at present is to be equipped with stable-pressure device for motor; but this only can solve the motor abnormality that external power source causes unusually to a certain extent; but can not be according to handling unusually in real time, especially cause the then safeguard measure timely and effectively of motor abnormality because of the motor internal coil fault.
The utility model content
The utility model has proposed a kind of self-monitoring motor for remedying the deficiencies in the prior art, the voltage of motor internal coil, current monitoring signal real-time feed back to control device, by control device motor is protected timely and effectively.
For achieving the above object, the utility model has adopted following technical scheme:
Self-monitoring motor comprises motor and control device, and motor and control device electrically connect, and output was connected to the motor power terminal after control device connected power supply, draws one or more tap feedbacks in the coil of motor and is connected to control device.Motor obtains electric energy from control device; if machine operation is unusual; unusual voltage, current signal are obtained in one or more taps that control device can be drawn from the coil of motor; thereby judge the abnormal work state of motor; and carry out the operation of whether cutting off the motor operation, thereby motor is protected timely and effectively.
As improvement of the technical scheme, be provided with the step-down module, control device connects power supply by the step-down module.
As improvement of the technical scheme, control device is provided with a plurality of input signal ends, comprises speed-regulating signal end, brake signal end, power supply voltage signal end, motor angle signal end, preserved signal end.Control device sends real time control command according to the signal of each input signal end to motor.
As technique scheme, described motor is a brushless electric machine, and the position sensor signal of brushless electric machine outputs to the motor angle signal end of control device.
Compare with prior art, the utlity model has following beneficial effect:
Motor is connected with power supply by control device; can not be subjected to the unusual influence of external power source; and the voltage of motor internal coil, current monitoring signal can be real-time feed back to control device, if any unusually then protecting timely and effectively motor by control device.
