Abstract
The utility model relates to a mini-type permanent magnet synchronous motor, comprising a rotating-resistant wheel which is arranged on a speed reduction gear for interlocking, an extensible resistant arm, an electromagnet and a controlling circuit. An instant impulse current which is output by the controlling circuit flows to the electromagnet. The extensible resistant arm which is driven by the electromagnet retracts and then resets rapidly, which results in that the rotating-resistant wheel is driven to rotate and the synchronous motor rotor is driven to rotate reversely in a stable state. A switch of the synchronous motor is realized when the impulse current is output by the controlling circuit.
Description
Branch art field
The utility model relates to a kind of permanent magnetism small synchronous motor, specifically is exactly the permanent magnetism small synchronous motor that direction of rotation can be controlled easily.
Background branch art
The miniature permagnetic synchronous motor of extensive use at present has modes such as orientation and non-directional rotation, but can not control commutation according to concrete Technology Need, and in some concrete applications, needs the direction of rotation of instant control motor to reach application purpose with this.
Summary of the invention
The purpose of this utility model is to overcome the weak point that the conventional synchronization motor can not be controlled commutation, thereby provide a kind of simple, convenient, low cost method, utilize synchronous machine to meet and stop the phenomenon that power is promptly reversed, design and be installed in the rotational resistance wheel that links with it on the reduction gearing a kind of comprising, can stop the telescopic arm that the rotational resistance wheel rotates, the flexible electromagnet of control telescopic arm, and the control circuit of control electromagnet.
Description of drawings
Accompanying drawing one is the utility model structural representation.
Accompanying drawing two is another embodiment of the present utility model.
Embodiment
Damping due to rotation wheel 3 is installed jig arm 5 by elasticity and is installed on the damping due to rotation wheel installation position 1 of reduction gearing 2, and damping due to rotation wheel 3 rotates in the same way with reduction gearing 2; Reduction gearing 2 is installed on the reduction gearing axle 6, with synchronous electric motor rotor 9 engagements; Damping due to rotation wheel 3 and synchronous electric motor rotor 9 reverse rotations, when touching with the position 8 of being obstructed of synchronous electric motor rotor 9, the damping arm 4 of damping due to rotation wheel 3 produces bounce, synchronous electric motor rotor 9 counter-rotatings, 3 opposite spins simultaneously of damping due to rotation wheel are touched the generation bounce with the position 8 of being obstructed of synchronous electronics rotor 9 again until damping arm 4, electronics rotor 9 reverse rotation once more synchronously, so circulation.Engraved structure 14 on the position 8 of being obstructed of perforate 13 on the damping due to rotation wheel 3 and synchronous electric motor rotor 9 has cushioning effect when damping arm 4 touches with the position 8 of being obstructed of synchronous electric motor rotor 9.
When flexible stop arm 10 normalities were stretched out, the A position or the B position that are blocked in damping due to rotation wheel 3 can not rotate damping due to rotation wheel 3 synchronously with reduction gearing 2, and stop synchronous electric motor rotor 9 reverse rotations, thereby form the directional synchronous motor of stable state.
When pulse current of control circuit 12 outputs, make electromagnet 11 adhesives, drive flexible stop arm 10 withdrawals, the A position of damping due to rotation wheel 3 or B position be suffered to stop release, damping due to rotation wheel 3 rotates in the same way until the damping arm 4 and the position 8 of being obstructed of synchronous electric motor rotor 9 with reduction gearing 2 and touches the generation bounce, electronics rotor 9 reverse rotations synchronously; Because flexible stop arm 10 has resetted, damping due to rotation wheel 3 stops and the deceleration tooth changes 2 rotations in the same way, and stops synchronous electronics rotor 9 reverse rotations, from and form toward the stable state directional synchronous motor of other direction rotation.
Control impuls electric current of control circuit 12 every outputs, synchronous electric motor rotor 9 promptly change direction of rotation and directed rotation, thereby reach the purpose of may command commutation.
