Description

Three-phase motor rotation direction semaphore}

This utility model is to determine whether the rotation direction is forward or reverse when using a three-phase motor or a machine with a three-phase motor as a component.

This utility model consists of a small generator, a hall sensor, and a permanent magnet. A hall sensor pcb assembly is attached to the stat of the small generator, and a permanent magnet is attached to the rotor of the generator. When the generator rotates to generate electricity, the hall sensor receives electricity and generates a signal by sensing the position of the magnet attached to the generator rotor.

When using a three-phase motor in the dark or in water, it is difficult to distinguish the direction of rotation, so it is often used incorrectly. The purpose is to prevent such misuse.

A signal generator capable of indicating the direction of forward and reverse rotation is installed on a three-phase motor or a three-phase motor of a facility that has a three-phase motor as a component.

Using this utility model, one person can do the work that two or three people used to do, and it is possible to increase safety and lower the failure rate of equipment.

This utility model, three-phase motor rotation direction signal generator is formed of a small generator, hall sensor pcb assembly, and a magnet. The magnet is attached to the rotor of the generator to form a three-phase motor rotation direction signal generator rotor (hereinafter referred to as ①), and a small By attaching the hall sensor pcb assembly to the stator of the generator, the three-phase motor rotation direction signal generator stator (referred to as ② below) is formed. By fixing ②, the generator circuit is formed. When the rotating body rotates, the small generator generates electricity and supplies it to the hall sensor, and the hall sensor detects the magnet rotation direction of ① and generates a signal. or by receiving a signal with the controller to control the direction of rotation.
