Embodiment Construction
[0046] In order to make the objects, technical solutions and advantages of the present invention, the present invention will be described in detail below in conjunction with the embodiments. It is to be understood that the specific embodiments described herein are intended to explain the present invention and does not limit the scope of the invention.
[0047] It should be noted that when the element is referred to as "fixed to" another element, it can be directly in another element or may exist in the hidden element. When an element is considered to be "connected" another element, it can be directly connected to another element or may exist at the same time. The term "vertical", "horizontal", "horizontal", "left", "right", and similar expressions are merely illustrative, and the only embodiment is not shown.
[0048] All technical and scientific terms used herein are commonly understood by those skilled in the art of the present invention, unless otherwise defined. The terms used...

The invention provides a motor rotor state monitoring method, which comprises the following steps that: a plurality of groups of Hall elements are fixedly arranged in a shell of a motor, and a plurality of Hall sensors in each group of Hall elements are uniformly distributed in the circumferential direction; and acquiring output voltage signals of one group of Hall elements in the power-on state, and judging the state of the motor rotor according to the output voltage signals of one group of Hall elements in the power-on state. The motor rotor state monitoring system not only can monitor the state of the motor rotor, but also can judge whether the Hall sensors are abnormal or not, and selects and switches the Hall elements when one group of Hall elements cannot work normally, so that the problem that the existing motor rotor state monitoring system cannot effectively monitor the state of the motor rotor for a long time is solved; the state of the motor rotor can be continuously monitored, and long-time effective operation of the motor is ensured. Correspondingly, the invention also provides a motor rotor state monitoring system.
Description
Technical field [0001] The present invention relates to the field of motor equipment, and in particular, there is a motor rotor state monitoring system and a monitoring method. Background technique [0002] The motor is also called a motor, which is an electromagnetic device that implements electrical energy conversion or transmission based on the electromagnetic induction principle. The motor includes a stator and a rotor, typically through the reverse rotation of the rotor to generate a drive torque, thereby converting electrical energy into mechanical energy, providing a power source for various mechanical power. [0003] In the existing motor rotor state monitoring system, the motor rotor position is often detected by a set of Hall sensors mounted inside the motor casing and the motor rotor steering. However, during the operation of the motor, the problem of damage to Hall sensor is prone to occur. Since only one set of Hall sensors are installed inside the motor casing, when...
