Description
Technical field
The utility model belongs to machine field, is specifically related to a kind of safe motor control system.
Background technology
In modern industry; motor is essential; its effect is to utilize power supply to realize the rotation of rotor relative stator; and outside output torque; in the process that rotor and stator relatively rotate; can produce a large amount of heats and the temperature of motor is raise, in the electric motor protecting equipment of existing small household appliances, generally be to be provided with Thermal Cutoffs in motor; when motor temperature is too high; Thermal Cutoffs fuses and the power supply input circuit of motor is disconnected, and motor shuts down, and this shows; in the prior art; in motor, add Thermal Cutoffs, play a role for avoiding too high the having an accident of motor temperature, but also have following defective:
1, because after the Thermal Cutoffs fusing, also stops the useful life of motor, limited the useful life of motor;
2, in the existing structure, can't adjust the fusing-off temperature of motor temperature fuse easily;
3, in the existing structure, the temperature regime in the time of can't being concerned about machine operation easily.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of electric machine control system is provided, and this control system is used more convenient, safety, and useful life is also higher.
The utility model is achieved through the following technical solutions:
A kind of safe motor control system comprises the stator and the rotor of motor, forms the power delivery loop between two power inputs of motor, is connected with temperature sensor on stator or rotor, and this temperature sensor is electrically connected with processor; Be provided with control switch on the power delivery loop, processor is electrically connected with control switch.
The utility model carries out sensing by the temperature sensor in the motor to the temperature in the motor, and temperature signal is transferred to processor carry out analyzing and processing, if motor temperature surpasses the scope of setting, then processor sends a switch controlling signal to control switch, control switch disconnects the power supply of motor, motor cools off, when temperature cross to be cooled to design temperature after, the processor control system makes it be in active state, and the user just can send signal to control switch by processor and normally start shooting or power-off operation; This shows, the utility model in terms of existing technologies, form control circuit by temperature sensor, processor and control switch, improve the promptness of temperature alarming, dynamically the temperature of motor is monitored and handled, avoid motor temperature too high and cause the accident, also avoid the damage of motor, improve the useful life of motor.
Further structure of the present utility model is:
Described temperature sensor is located on the described stator.Because stator maintains static, temperature sensor is located at convenient installation the on the stator.
Described processor can adopt single-chip microcomputer, can set the break-make temperature of control switch easily, and processor also can adopt other control circuit to realize.
This control system also comprises the display unit that is connected with described processor.Display unit can adopt single light-emitting diode, also can adopt LED charactron or LCD liquid crystal display, and the person of being easy to use observes the operating mode of motor.
Described control switch comprises controllable silicon and the relay that is connected in series, and this controllable silicon and relay all are electrically connected with described processor.Control switch adopts the two poles of the earth signal to amplify, and can reduce the spark of switch in the connection process, and fail safe is improved.
