Technical problem to be solved in the utility model is to provide for the weak point existing for above-mentioned existing electric drum a kind of for the servo-controlled electric drum of encoder at halved belt sorter upper set, realizing the object automatically controlled.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
One has been used at halved belt sorter upper set the servo-controlled electric drum of encoder, and comprise and being arranged on for driving the electric drum of conveyer belt transmission on halved belt sorter small vehicle, described electric drum comprises:
The one outer cylinder rotated;
One through described outer cylinder and axle is supported on the central shaft in described outer cylinder;
To be installed on described central shaft and to be wound with the rotating coil of excitation coil; It is characterized in that,
Described outer cylinder is configured with the grating of following described outer cylinder and rotating, described central shaft is configured with encoder, described encoder coordinate to detect the rotating speed of described outer cylinder and corner with described grating and the signal detected be delivered to with on the controller of servo.
In the utility model preferred embodiment, the two ends of described central shaft are bearing in by bearing and guide bearing chock on the inwall of described outer cylinder, described guide bearing chock is along with described outer cylinder rotation, described grating is arranged on one of them guide bearing chock, and described encoder is arranged on described central shaft near this one end of described grating.
In a preferred embodiment of the present utility model, offer a wire hole at described central shaft near this one end of described grating, the holding wire of described encoder is drawn described central shaft through described wire hole and is connected on the controller of described band servo.
Owing to have employed technical scheme as above, the utility model configures grating and encoder in electric drum, externally the rotating speed of cylinder and corner can detect, thus reach the object automatically controlled.The utility model also have rotate level and smooth, moment of torsion large, easily realizes intelligentized advantage, electronics commutation is flexible simultaneously, can realize square wave commutation or sinusoidal wave commutation, applied widely.
