Motor stator, sensor read heads are installed with housing.
Preferably, the braking mechanism that described claw brake disc and electromagnet are formed, electricity on normal condition lower electromagnet
Adhesive, claw brake disc is freely rotatable, and in the case of dead electricity, electromagnet release, iron core, which stretches out, stops that claw brake is spiraled
Turn.
Preferably, being provided with groove on described motor shaft, the clutch stop of claw brake disc endoporus side can be inserted into
The rotation of claw brake disc is prevented in the groove of motor shaft.
Preferably, described position sensor and the end face of claw brake disc side are fixedly connected using glue, this
Both are linked to be after entirety by sample significantly reduces than being installed separately the structure used its overall axial dimension in the past.
Preferably, described position sensor is Circular gratings structure design.
The beneficial effects of the utility model：Claw brake disc and position sensor are carried out integrated design by it, are solved
The brake device for electrical machinery of traditional form installs caused axially longer problem respectively with position grating scale, compact-sized, installation
Convenient, suitable for articulated mechanical arm, in cooperation, robot field has good application prospect and economic benefit.
