How to do 60 degrees Hall, how to divide electric car Hall into 60 degrees and 120 degrees

Say so much nonsense! Not a word on the issue.

Brushless motors can be divided into 60 degrees and 120 degree motors according to the electrical angle of the Hall element.

The external identification method is to look at the state of the three motor halls, the 60-degree motor has 000 and 111 states, that is, the three halls can output all low or full high, there is no 0 and 1 state, and the motor does not have 000 and 111 states, but there is a and state.

You can use the intelligent brushless controller to enter the self-test state to see the on/off judgment of the corresponding Hall status indicator. By the way, Tianjin Songzheng intelligent brushless controller can automatically identify 60 degrees, 120 degrees angle motors and operate normally.

Generally 120 degrees, the difference between 60 and 120 is that there are 3 groups of 120 degrees in the front and back motors, and the three are all facing up, which is 120 degrees, and the three are facing up on both sides, and the reverse side is 60 degrees.

Hello, the special motor for electric vehicles is either positive or reversed, which is called a 60-degree angle motor. There is a Hall in the middle opposite of the two next to it, called a 120-degree angle motor. To change the phase angle of the motor, you need to disassemble the motor and change the direction of the hall.

Just put the one upside down and you're good to go.

This can be distinguished by the phase difference of the output waveform from the Hall sensor.

120 degrees is the phase! How did you measure the motor Hall arrangement at 60 degrees? Hall is nothing more than monitoring the polarity of the induced magnetic field, and the three halls are arranged on a fixed position, with a fixed position!

I use Hall for motor sensing! You can't replace it with another Hall! And Hall is divided into positive and negative polarity and signal output lines!

According to the original arrangement and wiring, the hall was replaced, and the motor did not rotate, which means: 1) the hall specifications are incorrect; 2) Hall reversed; 3) The connection process is abnormal (there is no reliable connection).

If Hall has a switch type and a "line type", the switch type should be selected.

In addition, if the motor does not rotate, whether there is a problem with the matching controller must be eliminated first.

Also, what is the reason why the previous Hall was damaged, and how can you tell if it? The reason for this should also be ruled out.

There is nothing wrong with drawing gourds, but you must understand and eat thoroughly before you do it!

Generally speaking, at 205, the three Hall positions are 120 degrees and the three are 60 degrees.

When wiring, it is 120-240 degrees, which is a three-phase motor.

60 degrees and 120 degrees are not visible from the surface. There are only two kinds of wiring that are correct for 60 degree wiring, one is forward and one is reversed, and 120 degrees has 6 correct connections, three connections are forward and three connections are reversed.

Wiring method for brushed motors.

Brushed motors generally have positive and negative leads. Generally, the red line is the positive pole of the motor, and the black line is the negative plate of the motor. If the positive and negative poles are swapped for wiring, it will only reverse the motor and generally will not damage the motor.

Judgment of the phase angle of the brushless motor.

The phase angle of the brushless motor is the abbreviation of the phase algebraic angle of the brushless motor, which refers to the angle at which the current direction of the coil inside the coil changes in a power-on cycle of the brushless motor. There are two common phase algebra angles for brushless motors for electric vehicles: 120 degrees and 60 degrees.

Observe the installation space position of the Hall element to judge the phase angle of the brushless motor: the installation space position of the Hall element at 120 degrees and 60 degrees is different. The arrangement of the three halls of the 60-degree motor is the same, and the hall in the middle of the 120-degree motor should be flipped 180 degrees for installation.

The Hall element of the brushless motor has five leads, which are the common power supply positive of the Hall element, the negative of the common power supply, the A phase Hall output, the B phase Hall output, and the C phase Hall output. We can use the five Hall leads of the brushless controller (60 degrees or 120 degrees) to connect the positive and negative power supplies on the leads of the Hall element of the brushless motor, and connect the other three phase sensors A, B, and C to the leads of the Hall signal leads of the controller. Turn on the power of the controller, and the controller will supply power to the Hall element, and the phase angle of the brushless motor can be detected.

The method is as follows: use the +20V DC voltage of the multimeter, connect the black watch pen to the ground wire, and the red watch pen measure the voltage of the three leads respectively, and record the high and low voltages of the three leads. Rotate the motor slightly, let the motor turn a minimum magnetic pull angle, measure and record the high and low voltage of the three leads again, and so measure and record 6 times.

We use 1 for high potential and 0 for low potential, then, if it is a 60-degree brushless motor with 6 minimum magnetic relay angles continuously rotated, the measured Hall truth signal should be . Adjust the pin sequence change of the three Hall element leads, so that the three phases A, B, and C of the 60-degree brushless motor can be judged.

If it is a 120-degree brushless motor, continuously rotate 6 minimum magnetic pull angles, the measured Hall true value signal should change according to the law, so that the energizing phase sequence of the Hall element lead can be judged.

Wiring method for brushless motors.

There are 3 coil leads of the brushless motor, and 5 hall wires, and these 8 wires must correspond to the corresponding leads of the controller, otherwise the motor can not rotate normally.

The secret of the Hall of electric cars The 60 degree and 120 degree Hall converters can change the angle of the Hall on their own without disassembling the motor.

Mainly in the arrangement of the Hall elements inside the motor, the middle one is reversed is 120 degrees. It's time to take the motor apart and take a look.

Both positive and negative lines are shared. Each leads out a signal line. Generally, the positive line is red, and the negative line is black. The three Hall wires are yellow, blue, and green. When connected to the controller, the positive wire has to be positive, and the negative is negative. The other three signal lines are switched to each other until they rotate normally.
