In automation control area, the application of motor is very extensive, and it is mainly that electric energy is converted to mechanical energy, thereby produces corresponding mechanical control ability.
Motor speed is an important performance indexes of motor, and whether motor speed is stable has largely determined that whether the quality of motor is qualified, therefore, before Motor Production Test, need to test the stability of motor speed.But, current motor speed Detection of Stability device structure complexity, price is high, and need to regularly safeguard, and use cost is higher, and this makes small-sized motor manufacturer be difficult to bear, so and be not easy to popularize.
Summary of the invention
The present invention is directed to the problem in background technology, propose a kind of simple motor speed Detection of Stability method.
The present invention, for solving above technical matters, adopts following technical scheme:
A kind of motor speed Detection of Stability method, the Hall element that is provided with microcontroller in the method, is connected with the signal input part of microcontroller, and the hummer being connected with the signal output part of microcontroller, the method comprises the following steps:
Step 1: fix a disk on electric machine rotational axis, be embedded a magnet in the outer rim of disk;
Step 2: switch on power and make machine operation, electric machine rotational axis disc rotated, with the rotation of Hall element induction disk;
Step 3: the every rotation of disk one week, magnet makes Hall element produce an induced signal;
Step 4: microcontroller receives the induced signal of Hall element, and to judging the interval time of adjacent twice induced signal, if this interval time not in the time range of normal interval, microprocessor controls hummer report.
Preferably, described microcontroller adopts STC90C58RD.
Preferably, described disk adopts plastic disc.
Technique effect:
1, the present invention can detect motor speed stability effectively, and occurs when abnormal, to report to the police by hummer in motor speed stability.
2, method is simple, and testing cost is lower, is easy to promote, and is especially applicable to small-sized motor manufacturer.
Embodiment
Below technical scheme of the present invention is described further:
The Hall element that is provided with microcontroller in motor speed Detection of Stability method of the present invention, is connected with the signal input part of microcontroller, and the hummer being connected with the signal output part of microcontroller, based on above-mentioned device, this method mainly comprises the following steps:
Step 1: fix a disk on electric machine rotational axis, be embedded a magnet in the outer rim of disk;
Step 2: switch on power and make machine operation, electric machine rotational axis disc rotated, with the rotation of Hall element induction disk;
Step 3: the every rotation of disk one week, magnet makes Hall element produce an induced signal;
Step 4: microcontroller receives the induced signal of Hall element, and to judging the interval time of adjacent twice induced signal, if this interval time not in the time range of normal interval, microprocessor controls hummer report.
Microcontroller adopts the STC90C58RD of STC Corporation, and its internal processes has arranged the time that motor normal rotation one is enclosed; Disk adopts plastic disc, its fixing high rotating speed that needs to adapt to motor; Magnet is used for coordinating Hall element to carry out Speed sensing.In the time of the sensing range of magnet in Hall element, sensor can produce corresponding induced signal, therefore, the every rotation of motor shaft one week, disk (magnet) also correspondingly rotates one week, so magnet can make Hall element produce an induced signal, microcontroller receives after the induced signal of Hall element, judge the interval time (being the time that electric machine rotation one encloses this interval time) to adjacent twice induced signal, if this interval time is not in the time range of normal interval, microcontroller can control hummer report, defective to represent the speed stability of this motor.
