Abstract

The utility model belongs to the electrical machine manufacturing technology field. An obstacle identifiable electrical machine is mainly composed of a gear case, a motor, a steel pipe, a control system, and an electrical machine tail seat. The obstacle identifiable electrical machine is characterized in that the electrical machine includes a position sensor which monitors the position relationship between the electrical machine tail seat and a door-and-window roller shutter; the control system transmits a stop or return order according to an obstacle signal provided by the position sensor so as to realize the stop or return control of the motor. The electrical machine can sense whether or not a facility or a device driven by the electrical machine encounters an abnormal obstacle in the operation process. When the facility or the device encounters the obstacle, the obstacle can be identified and a stop or return action can be made, so the safety performance of the electrical machine operation is effectively improved.

Description

But a kind of cognitive disorders motor

Technical field

The utility model belongs to the motor manufacturing technology field.

Background technology

Institute is common in daily life for electronic garage rolling screen door, facilities such as electric rolling window, and people can open door and window through manual or remote control; Bring many convenience to people's life, but because there has been the object that should not exist a bit in some accident below these facilities; Also can bring many troubles to us; Like the flowerpot of putting on the windowsill, do not stop fully into or the automobile that sails out of, or the child that just is being at play of the student; When door and window is electronic when falling, will bring unnecessary property loss or personal injury.How can let occur under the above-mentioned unexpected situation, can make door or window meet these unnecessary barriers after, can stop, perhaps carry out vertical motion at once, be that commercially available common motor can't be accomplished.

Summary of the invention

The utility model is for solving the defective that above-mentioned prior art exists; But a kind of cognitive disorders motor is provided; Whether facility that this motor can the perception motor be driven or equipment run into improper obstruction in the process of operation; When running into obstacle, can discern and make and stop or the action of backhaul, improved the security performance of motor operation effectively.

The technical scheme that the utility model adopted is:

But a kind of cognitive disorders motor; Mainly constitute by gear box, motor, steel pipe, control system and motor tailstock; It is characterized in that said motor comprises the position transducer of a monitoring motor tailstock and door and window roller shutter position relation; The obstacle signal that control system provides according to this position transducer sends and stops or the return instruction, realizes stopping or return control of motor.

Described position transducer is a sensitive switch.

Described position transducer is a Hall element.

Said motor internal is provided with the transducer that a monitoring motor rotor speed changes; The rotation speed change signal that this transducer obtains is sent to control system; And cooperate jointly with the motor internal position-detection sensor; Position control system is made sending after the logic determines and is stopped or the return instruction, realizes stopping or return control of motor.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further description.

As shown in Figure 1, present technique scheme motor mainly is made up of driving, control system and motor tailstock.

Motor adopts the asynchronous permanent split capacitor motor of individual event, and when motor overcame load and promotes, the rotating speed of motor had certain variation with load; Before motor reached nominal load, internal motor rotor speed constantly reduced with the increasing of motor external loading, when motor rises; As run into obstacle; Load strengthens suddenly, and the motor rotor rotating speed is also at once corresponding slack-off suddenly, and the utility model can be measured the unexpected variation of motor rotor rotating speed through similar means such as for example Hall elements; Can judge the motor outside and whether be hampered, thereby motor made stop or the action of backhaul.

But; When the rotating speed of electric motor is not situation clearly along with the variation of load in decline process again takes place; Utilizing the relative effect of mode of measuring motor rotary speed is not clearly, realizes motor range control so the present technique scheme concerns through the position between monitoring motor tailstock and the reel.Have the gap of certain angle a between the reel of motor tailstock and fixed gate window; And work as the door and window sheet in the process of operation downwards; Because the effect of the weight of door and window sheet self; Position relation between reel and the tailstock is initial home position (initial condition as shown in Figure 2) for each parts of direction towards gravity are in contact with one another; When the door and window sheet runs into obstacle, the door and window sheet will stop to move downward, thereby reel also stops the rotation in succession; The still operation downwards of motor this moment is so originally because action of gravity contacts with each other the parts of applying owing to there is the gap, under the drive of motor; No longer fit to produce and separate; Before being separated to the maximal clearance (chance failure condition state as shown in Figure 3), motor is through the element in this gap of arranging in advance, like sensitive switch; Thereby Hall element or other sensing equipments are discerned the generation in this gap and are judged in the decline process and to produce the situation that runs into obstacle, let motor stop or backhaul.
