Problems solved by technology

[0002] In the past, the start-up, synchronization and working status of the motor packaged inside the instrument could not be monitored through external detection. The tester often confirms whether the motor is started by listening closely. As for whether the motor is running well, only Judging from experience, this method lacks scientificity, and an accurate and reliable motor automatic detection technology is extremely needed to accurately transmit relevant parameters of motor operation.

Embodiment Construction

[0015] like figure 1 As shown, the motor self-inspection device is composed of a motor self-inspection magnet 1, a self-inspection coil 2 and a self-inspection shaping circuit. The motor is located in the inner cavity of the float assembly composed of the instrument float housing and the float cover. The self-inspection magnet 1 is embedded in the outer circumference of the rotor body of the motor, and the self-inspection coil 2 is installed on the axial end surface of the inner cavity of the float assembly. Above, the self-test shaping circuit is included in the supporting electronic box. When the motor rotates at high speed, the self-inspection magnet 1 rotates together with the motor rotor, and an induced potential is generated on the corresponding self-inspection coil 2, forming a periodic AC signal similar to a sine wave, which is sent to the self-inspection shaping circuit , and then output a square wave signal with a certain frequency and amplitude after amplification,...

Abstract

The invention discloses an automatic detection device for a motor. The device consists of self-inspection magnetic steel, a self-inspection coil and a self-inspection shaping circuit, wherein the self-inspection magnetic steel is embedded in the outer circumference of a motor rotor and rotates along with the motor rotor; the self-inspection coil is arranged on an axial end face of a cavity of a motor instrument float assembly to generate induction electromotive force; and the self-inspection shaping circuit which is arranged outside the motor is used for amplifying, comparing and shaping the induction electromotive force generated by the self-inspection coil of the motor, performing frequency division and then outputting a detection signal. The self-inspection magnetic steel is made of a hard magnetic material; the magnetized magnetic steel has lasting and stable magnetic property; the self-inspection magnetic steel is easy and reliable in mounting; the self-inspection coil is arranged on the axial end face of the cavity of the float assembly; and the float assembly is provided with a mounting hole special for fixing the self-inspection coil, so that the self-inspection coil has a reliable adhesion position, and the problem of unreliability in adhesion of the self-inspection coil is completely solved. The device is applicable to self-inspection modes of various gyroscopic instrument motors, is easy to design, process and manufacture, and facilitates real-time monitoring of an overall process of a starting state and a working state of the motor in a gyroscopic instrument.

Description

technical field [0001] The invention relates to a motor automatic detection device, in particular to a device for realizing real-time detection of the working state of the motor inside the instrument, which is applicable to the motor self-test of various precision gyro instruments, and belongs to the technical field of machinery and electronics. Background technique [0002] In the past, the start-up, synchronization and working status of the motor packaged inside the instrument could not be monitored through external detection. The tester often confirms whether the motor is started by listening closely. As for whether the motor is running well, only Judging from experience, this method lacks scientificity, and an accurate and reliable motor automatic detection technology is extremely needed to accurately transmit relevant parameters of motor operation. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the...
