Abstract

The utility model relates to a miniature controllable-switching permanent-magnetic synchronous motor which comprises linked rotating resistance wheels installed on a speed reducing gear, a telescopic blocking arm, an electromagnet and a control circuit. The control circuit outputs instant pulse current to the electromagnet which is connected with the telescopic blocking arm to retract and rapidly reset, the rotating resistance wheels are rotated, and a rotor of the synchronous motor is reversely rotated, and form a stable state. The control circuit outputs the pulse current every time, and the synchronous motor realizes swtiching once.

Description

The miniature permagnetic synchronous motor of controlled commutation
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, the direction of rotation that all needs to control motor immediately reaches 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, the may command rotation reaches the telescopic arm that resistance wheel rotates, the flexible electromagnet of control telescopic arm, and the control circuit of control electromagnet.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Rotational resistance wheel 3 is installed folder hole 5 by elasticity and is installed on the rotational resistance wheel installation position 1 of reduction gearing 2, and rotational resistance 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; Rotational resistance 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 resistance arm 4 of rotational resistance wheel 3 produces resistance, synchronous electric motor rotor 9 counter-rotatings, 3 opposite spins simultaneously of rotational resistance wheel are touched the generation resistance with the position 8 of being obstructed of synchronous electronics rotor 9 again until resistance arm 4, electronics rotor 9 reverse rotation once more synchronously, so circulation.
When flexible stop arm 10 normalities were stretched out, the A position or the B position that are blocked in rotational resistance wheel 3 can not rotate rotational resistance 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 suffered resistance in the A position of rotational resistance wheel 3 or B position discharges, rotational resistance wheel 3 rotates in the same way until the resistance arm 4 and the position 8 of being obstructed of synchronous electric motor rotor 9 with reduction gearing 2 and touches electronics rotor 9 reverse rotations synchronously; Because flexible stop arm 10 has resetted, rotational resistance 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.
Pulse 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.
