My motor showing different connections for low voltage which is 1,7,6 to L1 and 2,8,4 to L2 and 3,9,5 to L3 can you explain it please

Your motor is a Delta connected Dual-Voltage Motor: 3q0ds8402hawyzjwb3qrnh43-wpengine.netdna-ssl.com/wp-content/uploads/2016/05/Screen-Shot-2016-05-16-at-11.10.39-AM.png

@antoniorosario39215 жыл бұрын
This video is truly on point and detailed. I went to my onsite assessment with PepsiCo Yesterday and the part of the assessment was based on a black box test. They require you to connect a 3 phase motor. Only 20% of interviews actually pass the first part of the assessment, and if you cannot connect the wiring for a 3 phase motor in 8 min. the interview is over. Because of this video I completed the task in 4min.

Great job in clarifying that the second and the third diagrams for the parallel wye have that important difference in the neutral points connection. The second one indeed helps in visualizing the connection arrangement. Thanks for the video and great information provided with the wiring explanations, I was looking for a little "memory refresher" but I ended up learning more with this video. Never stop learning!

Excellent. In a former job, I used to sometimes change out three phase motors. I always followed the diagram on the inside of the cover plate for the junction box on the motor, bumped the motor to check rotation and swapped two if the rotation was wrong. Now I understand what always seemed like a strange setup for the low voltage, although I had pretty well figured out that it involved putting windings in parallel for the low voltage and in series for the high voltage.

Good afternoon. I am currently studying industrial electricity basics. Arround munute 4:20, you mention that in order to reverse the rotation of the motor you just have to switch any two of the incoming conductors. My question is: in the original instalation, how do I know which line is L1, L2 and L3 respectively?
@PeteVree6 жыл бұрын
The conductors are colour coded for each phase (colour codes vary with each country), or in the panel, disconnect, etc. the conductors will be connected to terminals with the designation L1 L2 L3. Even if nothing was labelled and you had 3 unmarked conductors, you could connect the motor, turn it on briefly and look at the direction of rotation. If it was in the wrong direction, just interchange any two conductors. If the application does not allow for the motor to turn in the wrong direction, you could use a phase rotation meter (a meter that connects to the 3 incoming lines and tells you whether the motor will turn CW or CCW)

That was really helpful. Thank you.

With a pencil and paper I wrote out all 6 possible linear combinations of the three input lines (123, 132, 213, 231, etc). Then note that they are arranged in a repeating circle, with no defined starting point. So, you can see that of those six possibilities, only two are unique, the rest are rotational variants. So, even if you don't know which one is exactly L1, L2, or L3, there are only two possible ways to order the lines. Swap any two lines and you get the opposite configuration, giving a motor with opposite rotation....

Question: I'm going to install a used system 27 Hp bitzer compresor, for ultra freezing, this system was assembly in china, installed originally in Seattle Washington, and I'm goin to install here en Baja Sur Mexico. The evaporator has 4 Chinese motors 3/4 hp 220/ 380 V, and each motor has 8 leads, 6 black lead numbered from 1 to 6 and 2 more Yellow leads. I notes that it were connected to 220 volt 3 face, L1 to leads 1,5 L2 to leads 2,6 and L3 to leads 3,4 The other two yellow lead i don't know exactly where were connected, I'm assuming something for controls. Did you saw this kind of connections before? do you have any idea what the yellow leads are for? there is not information at all in this motor and system, no serial numbers no model numbers only the compresor who was made in Germany. The evap motors only has the voltage, Hp and amperes that's it. Thank you in advance. I'm apologize, my English is not the best.
