Description

Motor winding coil on-off detection device

Technical Field

The utility model relates to the technical field of motors, in particular to a motor winding coil on-off detection device.

Background

Before the motor is assembled, the winding wires of the motor coil are required to be detected, and the detection is mainly on-off, and the traditional manual measurement method mainly comprises an electric pen method and a universal meter method, and comprises the following specific operation steps: and (3) an electric pen method: one electrography head is placed at one end, and the other electrography head is placed at the other end, and if a nourishing sound is made, the electrography head represents that a passage is smooth and works normally. The method is simple and feasible, but the measurement result is not accurate. Multimeter method: the potential gear of the universal meter is adjusted to a direct current resistance gear, two test pens are respectively contacted with two ends of the coil, and at the moment, the universal meter can display the resistance value of the coil, so that whether the coil is normal or not is judged. This method is more accurate than the electrography method, but requires calibration of the multimeter prior to testing, and is somewhat more complex to operate.

The modern electronic measurement method mainly comprises a digital multimeter, an LCR bridge and an oscilloscope, wherein the tools have more stable and accurate performances, and the specific operation is as follows: digital multimeter method: besides the manual method, the digital multimeter can automatically detect whether the winding of the coil is damaged, whether a notch or short circuit occurs or not, and the like. The digital multimeter can output clear digital results, and the operation is more convenient. LCR bridge method: the LCR bridge can detect whether a problem exists in the coil more quickly by adding an alternating current power supply to the circuit and measuring the resistance, capacitance and inductance values. An oscilloscope method: the oscilloscope can convert the circuit signal into a waveform diagram mode, so that the problem in the coil can be displayed more intuitively. This approach is more intuitive than the first two approaches, but is also more complex.

Because the number of the winding wires of the motor is large, before the traditional measuring method measures the on-off state of the coil, two ends corresponding to the winding wires of the motor coil need to be found, so that the testing efficiency is low and the operation is complex. Although the electronic measurement method is accurate and stable, can detect more tiny line problems, and has great advantages especially in the case of high-precision measurement, the electronic measurement method requires more expensive equipment and personnel experience and is not suitable for industrial production detection.
