Definitions
- An object of the present invention is to easily determine whether the rotation direction is a forward rotation or a reverse rotation when using a three-phase motor or a facility machine having a three-phase motor as a component.
- the present invention 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.
- the hall sensor It is a signal device that receives electricity and detects the moving position of the permanent magnet of the generator rotor and sends a detection signal.
- a three-phase motor rotation direction signal generator is attached to a three-phase motor or equipment using a three-phase motor to indicate the forward and reverse rotation directions of the three-phase motor with a traffic light or attached to a control to control the rotation direction.
- the signal generator of the present invention Due to the presence of the signal generator of the present invention, one person can do the work that two or more people used to do, thereby increasing production efficiency, increasing production safety, and preventing equipment failure.
- Figure 1 Parts diagram of a three-phase motor rotation direction signal generator.
- Figure 2 Assembly and installation of a three-phase motor rotation direction signal generator and a three-phase motor.
- Figure 3 An example of installing a three-phase motor rotation direction signal generator in a three-phase submersible pump.
- a three-phase motor rotation direction signal generator is installed in the pen direction of the three-phase motor. By connecting the signal light to the signal in two colors, the direction of rotation can be judged as a traffic light.
- a signal is also provided on the head cover part of the three-phase submersible pump using a three-phase motor as a component. By installing a generator and installing two colored traffic lights, the direction of rotation in the water of the submersible pump can be known by the color of the traffic lights.
- the three-phase motor rotation direction signal generator of the present invention is composed of a small generator, a Hall sensor, and a permanent magnet.
- Permanent magnets are attached to the rotor of the generator to form a three-phase motor rotation direction signal rotor (below 1), and the hall sensor is attached to the stator of the small generator.
- Three-phase motor rotation direction signal stat is formed (hereinafter referred to as 2)
- the small generator supplies electricity to the hall sensor of 2, and the hall sensor It detects the rotation of 1 and sends out the rotation direction signal. Receives the signal as a traffic light and displays the rotation direction with various colored lights and controls the rotation direction when it receives the control.
- a signal generator can be used by attaching a signal generator.
