Zero-clear meter meter for motor
There is no limit to creativity, and the instrument is invented. Today we introduce a patent for a national invention, a zero-meter meter for motors. The patent was filed by Nan'an Shengsheng Technology Co., Ltd. and was granted an authorization announcement on November 6, 2018.
Description
The invention belongs to the technical field of electric meters, and particularly relates to a clearable electric meter meter for a motor.
Background of the invention
In order to realize the meter meter that can count the digital wheel to return to zero, and the meter counts the digital wheel back to zero, the accuracy of the meter is not affected. A meter meter that can count the digital wheel back to zero is now provided. This meter does not affect the accuracy of the meter when the digital wheel is zeroed. The electric energy meter acceler capable of returning to the digital wheel comprises a permanent magnet type stepping motor, a meter bracket, and a counter component composed of a character wheel, a carry wheel and a reduction gear, and one of the stepping motors Two permanent magnet rotors are fixedly spaced on the rotating shaft, and two sets of stators and coils respectively corresponding to the two permanent magnet rotors are arranged on the frame, and when the two corresponding stators and rotors respectively work, the rotation of the rotor The opposite directions are used for counting and clearing respectively; the perpendicular magnetic poles of the two permanent magnet rotors intersect at a projection line on a plane perpendicular to the motor shaft, and do not coincide, and the angle formed by the intersection is in the range of 10-180 degrees. .
In order to facilitate maintenance and disassembly, an existing improvement is to improve the structure of two permanent magnet rotors on a rotating shaft of the stepping motor at intervals: the motor shaft of the stepping motor is sleeved through the shaft connector The rotating shafts of two permanent magnet rotors are coupled so that the permanent magnet rotor can be driven by a stepping motor. However, current shaft connectors often have stress due to the rotation of the shaft due to the unreliable coupling, which may cause the motor shaft or The shaft has a problem of flexion and extension.
