Abstract
A single-phase capacitor servo motor comprises a casing, twelve sets of windings, a stator mandrel and a rotor, wherein, the windings form a sextupole symmetrical winding; the stator mandrel has twenty four grooves. The motor which adopts special winding form has a compact structure and locked-rotor preventing characteristic and avoids overheating during full load or locked rotor of the motor; moreover, the output moment of the motor has stable characteristics and can meet the requirements of different actuators for using the motor.
Description
Technical field
The utility model belongs to the servomotor technical field, is specifically related to the single-phase capacitance formula servomotor with anti-blocking rotating function that a kind of actuator uses.
Technical background
Traditional actuator has with servomotor: (1) SZ series mini DC servo motor, this motor has armature winding and excitation winding, anti-stall, rated speed all≤1500 rev/mins, carbon brush is arranged, working life is undesirable, torque characteristics is better.(2) SY series mini DC servomotor, this electric machine structure is simple, does not have excitation winding.But torque characteristics is not as the SZ serial motors, and all the other are identical with the SZ serial motors.(3) ADP Series AC servo, this serial motors have excitation winding and control winding, need to adopt different input voltages, also not anti-stall, and torque characteristics is not as DC servo motor, but the life-span is long.So generally speaking, traditional servomotor all can not be prevented stall, can not will take into account moment of torsion, useful life and power-off brake etc. effectively simultaneously, makes their characteristic reach the optimization and the coordinating and unifying.
Summary of the invention
The utility model is at the prior art above shortcomings, purpose be to design a kind ofly have anti-stall characteristic, can also possess the power-off brake function, the similar DC servo motor of moment of torsion output characteristic, long single-phase capacitance formula servomotor of life-span.
The technical solution of the utility model is as follows:
Single-phase capacitance formula servomotor comprises casing, winding, stator core and rotor, it is characterized in that winding is 12 groups, forms the sextupole symmetric winding, and stator core is 24 grooves.
In addition, the rotor of motor can also connect brake, brake is assemblied in the casing jointly by braking star wheel, brake block, plug in car armature, spring and coil and constitutes, brake block is loaded on the braking star wheel, brake armature is arranged between brake block, coil and the spring, and a side is in abutting connection with brake block, a side adjacent coil and a spring, the spring overcoat adjustment part makes spring shaft to being butted on the brake armature by it.
This motor has adopted special winding configuration, and compact conformation has anti-stall characteristic, and it is overheated can not produce under the fully loaded or stall situation at motor.And motor has also designed power-off braker, and control is simple, does not need the cut-out switch relevant with location or torque during use, and rotating speed is low, and the life-span is long.And this motor output torque characteristic is harder, can satisfy the requirement that multiple actuator uses motor.
Description of drawings
Fig. 1 is the structure chart of this motor;
Fig. 2 is the overall structure figure that this motor has power-off brake mechanism.
Embodiment
Referring to Fig. 1, motor is made of shell 3, winding 1, stator core 2 and rotor 4.Stator core 2 and shell 3 casting dresses.Sextupole symmetric winding 1 is flush-mounted in the stator core 2, and rotor 4 is loaded in the stator hole, and armature spindle 5 usefulness bearing fixing are on shell 3 and front end housing, and winding is 12 groups, forms the sextupole symmetric winding, and stator core 2 is 24 grooves, has anti-blocking rotating function.
This motor has the structure of power-off brake mechanism referring to Fig. 2, and brake mechanism is made of braking star wheel 6, bumper post 7, brake block 8, brake armature 9, spring 10, adjustment part 11, coil 12, brake casing 13.Braking star wheel 6 cutting ferrules are driven by armature spindle 5 on the step of armature spindle 5, braking star wheel 6 overcoat brake blocks 8, and brake block 8 is supported by bumper post 7, and brake block 8 can elasticity be moved axially.Between brake armature 9, adjustment part 11 and the spring 10, one side is in abutting connection with brake block 8, one side adjacent coils 12 and spring 10, spring 10 overcoat adjustment parts 11, brake armature 9 forms sliding connection by pin and adjustment part 11, and by adjustment part 11 spring 10 axially is butted on the brake armature 9.
The operation principle of this motor is as follows: work as energized, and brake coil energising adhesive, this moment, brake was in non-on-position, and simultaneously symmetrical sextupole winding energising produces rotating magnetic field and makes the rotor rotation, and armature spindle drives actuator's work.When cutting off the power supply, the brake coil outage discharges brake armature, and brake armature contacts the generation friction with brake block under the effect of spring, and this moment, armature spindle also can't rotate under the effect of load external force, realized braking function.
