Abstract
The utility model discloses an eccentric double-pit permanent step-by-step motor which is used in a counter of the electromechanical integration for driving an electric energy meter, comprising rotors, stators, coils, a front plate, a back plate and a steel needle. The stators are penetrated into the hole of the coil and then are loaded into the back plate; the steel needle is pressed in the rotors and is loaded in the back plate, and then the steel needle is assembled with the front plate. The rotors are three pairs of permanent magnet rotors. The stepping angle is 60 DEG in space, which can avoid the situation that the acting force of the stators vanishes when the rotors switch to the 90 DEG in space, and the hidden trouble of the malfunction or the out-of step of the motor can be eliminated to make the counter work normally. The stators are designed into the eccentric structure, and one pair of pits are symmetrically bored on a circle where the air gap is formed by the stators to make the pair of the pits face one pair of the poles of the stators whose polarity is opposite to the other two pairs of the poles, so that the output torque of the motor can be enlarged.
Description
Technical field
The utility model relates to a kind of centering type concave-concave hole permanent-magnet stepper motor that drives electric energy meter with stepping motor, especially the electromechanical register of register.
Background technology
Electric energy meter adopts single-phase centering type permanent magnetic step motor or single-phase pit type permanent magnetic step motor usually with electromechanical register (hereinafter to be referred as register) at present, these two kinds of stepping motors all adopt the rotor of a pair of utmost point, owing on the structural principle and technologic reason, when rotor being run to be not subjected to the position of stator field effect, motor itself is prone to stuck or step-out, causes electric energy meter normally not count.
Summary of the invention
The purpose of this utility model is to provide a kind of can eliminate the hidden danger that stuck or step-out take place motor, and the centering type concave-concave hole permanent-magnet stepper motor that output torque is increased, and it has overcome the shortcoming that prior art exists.
The purpose of this utility model is achieved in that it comprises rotor, stator, coil, front plate, rear plate and draw point, and stator penetrates and reinstalls rear plate in the coil hole, draw point be pressed into rotor and the rear plate of packing in assemble with front plate again.
Described rotor is three pairs of utmost point p-m rotors; its step angle is 60 ° in space; when a pair of utmost point rotor of having avoided step angle and be 180 ° in space forwards 90 ° to; the state that the rotor active force goes to zero; promptly eliminated the hidden danger that stuck or step-out take place motor, thereby guaranteed that the electromechanical register normally counts.
Described stator adopts eccentric structure, and on the circumference of its formation air gap, have a pair of pit symmetrically, and make this to pit over against the extremely opposite utmost point of a pair of and other two couples of described rotor, because the existence in concave-concave hole, when coil electricity, stator is to this reaction force attenuation to the utmost point, thereby the whole output torque of motor is increased.
The beneficial effects of the utility model are: both eliminated the hidden danger that stuck or step-out take place motor, guaranteed that register normally counts, output torque is increased.
