Description
Technical field
The utility model belongs to motor production technology and terminal uses technical field, and in particular to a kind of motor sweeps hall protection
Device.
Background technology
Motor during the manufacturing, due to using bearing（Other modes rotate rotor supports）Realize the rotation of rotor
Transfer driven equipment operation.In the process due to the manufacture of bearing class and using that can make the bearing have a terminal life, at this
It is bearing cycle actual life that is difficult to maximum control, so that electric machine chamber-sweeping burns out determining in the terminal life time of individual bearing
Son.
During terminal user's use, due to the shadow of maintaining, running environment and the other not equal reason of grease type
Ring, make motor bearings, bearing position（Rotor, end cap）, actual life is more difficult to analysis and judges and control, so as to cause electricity
Machine sweeps thorax and burns out stator.
Because sweeping thorax is not belonging to electric prospection scope, mechanical category is not belonging to again, therefore sweep thorax to burn out motor is motor
Bearing life is ended.Due to motor under current manufacture and operating condition to motor bearings, bearing position（Rotor, end cap）After damage
Directly sweeping thorax burns out motor stator, causes maintenance cost and enterprise's production run cost directly to increase.In the use of terminal user
During, electric machine chamber-sweeping damages and causes to shut down.The now loss of startup-shutdown and production quality loss are huge.
The content of the invention
The utility model in order to solve the problems, such as because bearing life or other component wears cause motor sweep hall damage, and then
A protector is swept there is provided a kind of motor.
The utility model is adopted the following technical scheme that：
A kind of motor sweeps a protector, including transformer, rectifier bridge stack and normally closed relay, the output end of transformer with it is whole
The ac input end for flowing bridge heap is in parallel, and normally closed relay is parallel to the DC output end of rectifier bridge stack, normally closed relay it is normally closed
Switch is in the main circuit of the control loop between motor shutdown switch and power supply；The normally closed relay and rectifier bridge
It is in series with the link circuit of heap and sweeps hall switch, it is the normal open switch being made up of rotor and motor stator to sweep hall switch.
The input of the transformer is connected with the power supply of motor, that is, the transformer and motor for sweeping a protector are shared
Same power supply, also can outer power supply source.
The transformer for sweeping a protector, rectifier bridge stack and normally closed relay are integrated in the terminal box of motor, sweep hall
One end of switch is connected with motor stator, and the other end is connected with the bearing outer arc of rotor or rotor.
The output DC voltage of the rectifier bridge stack is 24V.
It is described sweep a protector sweep hall protection control process be：
When motor is swept, rotor and motor stator mutually insulated are not contacted, and sweep hall switch in normally open,
A protector is then swept for off-state, the normally closed relay switch of a protector is swept in normally off, the power supply master of motor
Closing of circuit, motor runs well；
Motor hinders when sweeping for some reason, and rotor and motor stator wipe contact, sweep hall switch closure, normally closed relay
Adhesive, then the normally closed switch disconnection of normally closed relay, disconnects the power supply main circuit of motor, and stopping is powered to motor, electricity
Machine shuts down, and realizes the protection to motor stator.
The utility model has the advantages that：
1st, the protection that hall burns out can be swept to stator in production using protector described in the utility model and plays direct effect, subtracted
Stator is lacked and has damaged maintenance cost, while can realize to bearing, bearing position（Rotor, end cap）Faiture alarm is protected, and be it also avoid
For a long time shut down and by with motor for costs such as storehouses；
2nd, the utility model and motor can share same power supply, then be changed using the transformer of modularization Width funtion
Output galvanic current pressure, can effectively ensure that and sweep a stability of protector circuit operation, play real-time guard effect；
3rd, each element for sweeping a protector can be integrated in the terminal box of motor, and installation volume is small, and wiring is simple, changed
It is convenient, and the original structure of motor will not be changed；
4th, the circuit element that protector described in the utility model is used is few, and with motor shared input AC power,
Low cost, compares because sweeping electrical machmary maintenance expense caused by hall（Even motor is directly resulted in scrap）, the huge production and operation can be saved
Cost.

Specific embodiment
With reference to accompanying drawing, specific embodiment of the present utility model is described further：
Motor as shown in Figure 2,3 sweeps a protector, including transformer 7, rectifier bridge stack 8 and normally closed relay 9, transformer
7 output end is in parallel with the ac input end of rectifier bridge stack 8, and normally closed relay 9 is parallel to the DC output end of rectifier bridge stack 8,
The normally closed switch 12 of normally closed relay 9 is in the control loop between motor shutdown switch SB2 and power supply（Insure
Link circuit between FU2 and motor start switch SB2）；Gone here and there in the normally closed relay 9 and the link circuit of rectifier bridge stack 8
It is associated with and sweeps hall switch 10, it is the normal open switch being made up of rotor 1 and motor stator 2 to sweep hall switch 10.
When motor is installed, make to be insulated between stator and rotor（Dress insulation bearing or other manner make stator rotor exhausted each other
Edge）, the trouble point mutually rubbed with stator rotor, as the sampled point for sweeping thorax signal, connects stator and rotor or the connection of bearing outer arc
A controller loop is swept, controlling alarm output is made after thorax protector is changed through sweeping, controlled using output signal disconnected to motor
Electricity is shut down.
Insulation bearing outer arc when lead is connect, by end cap or tegillum alignment bearings race diameter side punching tapping, with insulation
Be crimped on lead on insulation bearing outer arc by nut
Thorax protector power supply is swept to be powered by motor power supply（~380V）, by the transformer of modularization Width funtion, become
Into suitable actuating of relay voltage DC24V, and synthesize and the integrated module of relay output sweeps thorax protector.Sweep thorax protection
Device DC24V makees signal acquisition, reduces the interference of alternating current and electromagnetic wave to signal.The rotten rear high voltage of lubricating oil product is reduced to hit
Wear, export the advantage of glitch.
Specific control process of the present utility model is as follows：
When motor is swept, rotor 1 and the mutually insulated of motor stator 2 are not contacted, and sweep hall switch 10 in normally opened
State, then sweep a protector for off-state, sweeps the switch of normally closed relay 9 of a protector in normally off, the confession of motor 11
Electric electric power main circuit closure, motor runs well；
Motor hinders when sweeping for some reason, rotor 1 and the CONTACT WITH FRICTION of motor stator 2, sweeps hall switch 10 and closes, normally closed
The adhesive of relay 9, then the normally closed switch 12 of normally closed relay 9 disconnect, disconnect the power supply main circuit of motor, stop to electricity
Machine is powered, and motor shuts down, and realizes the protection to motor stator 2.
Wherein, the module or element that specified otherwise is not made in the utility model are prior art.
