Problems solved by technology

These two kinds of driving elements are very effective for loads with small strokes, and the reciprocating motion range is generally within ±30°, but for loads with super large strokes, such as ±50°, there are fatal flaws, and it is even impossible to achieve
For rotary voice coil motors, since the thickness of the yoke is proportional to the size of the rotation angle, the volume and weight of the motor will increase sharply after the rotation angle reaches a certain level, and the structure is seriously unreasonable
For the limited corner torque device, the pitch of the coil is proportional to the size of the corner. After the stroke is too large, the end of the coil is too long, and the loss of the end and the increase in size cannot be tolerated.
[0003] Therefore, in the existing technologies and products, there is still no driving element that can meet the driving requirements of super large strokes and is suitable for a limited range of rotation angles.

Abstract

The invention relates to a limited angle torque device with concentrated winding of an assembled iron core, which belongs to the technical field of drives. The number of stator core pieces of the stator is the same as the number of magnetic poles of the rotor; each stator core is equipped with winding slots for mounting uniformly distributed radial concentrated windings. After the winding slots are insulated, radial concentrated windings are used in each stator core. Winding on the iron core, the winding directions of the coils in all the winding slots are the same, all the stator cores are installed on the outside of the rotor and spliced ​​into a circle, and the outer sides of all the stator cores are fixed by the casing, the winding direction of the windings on every two adjacent stator cores Instead, all stator core windings are connected into one by external wiring to form a complete stator winding. The invention is very suitable for the occasion of reciprocating drive with limited rotation angle of super large stroke.

Description

technical field [0001] The invention relates to a limited-rotation-angle torque device, in particular to a stator of a limited-rotation-angle torque device with an assembled iron core concentrated winding, and belongs to the technical field of drives. Background technique [0002] Some drive units are often used in many devices to drive some loads to reciprocate within a limited range of rotation angles. If the load is continuously rotating, it is most suitable to be driven by a traditional servo motor. For limited angle loads, rotary voice coil motors and limited angle torque devices are most suitable, because these two types of motors are driven by single-phase winding DC, and the circuit is simpler. These two kinds of driving elements are very effective for loads with small strokes, and the reciprocating motion range is generally within ±30°, but for loads with large strokes, such as ±50°, there are fatal flaws, and even cannot be realized. For rotary voice coil motors,...
