Thanks for clarifying the motor windings and the attached link. This is very useful information and not easy to find out . Thats why i really wanted to know this subject fully. I have recently studied motors at trade school but they did not cover 2 speed. I will have a good read of this in the next week or so and might have a further question but hopefully i get it. Definitely a thumbs up for this. Thank you. Michael

Thank you! came across one of these today, was very confused

We are replacing a 2 speed motor at the moment. We found 4 wires on the motor side, U1, V1, W1, 1 and can't seem to figure out where the wire that is labelled 1 would go. It is an OEM motor that has been repaired over the years. The tech who used to wire it is no longer with us and no one knows where the wire would go. The motor that came off only had 3 wires on each side. Anyone have any insight they can share?

Good illustration. Could you plz do more other schematics showing the energized states .

Boss in high speed mode for holding k3 u used an additional NO of k2 but I think one NO of k2 sufficient for that, is that mandatory? Thanks

Hi. Was this presentation usefull for you ? If yes give me a thumb up. If not leave me a comment why and the next one will be better :)

Hi! This is a good video. But it would be better if you showed how the motor windings are connected through the contractors. Because a two speed motor is a special type motor. Thank you.

Hi. Do you have info on how to wire one of these 2-speed Dahlender motors to a VFD?

[ikbalmaulana]

Apakah ini menggunakan Kontaktor khusus dan push button khusus untuk menambah kecepatan pada motor 3 phase

[Tbose]

Thanks for the video can i have a dual speed video where I'll be using a seletor switch for slow n fast configuration? With explanation please👏

[atikahmad]

Power wiring break with rectifier please one video same video

[MrHazaraak]

thanks for usefull it Delta/star motor or?

[VinuPrasad-rm]

In this condition how will be the motor winding

[zeeshanahmad]

Sir
2 speed motor he
Iski name plate missing he
Aur jo information available he
(1) 6 wire nikal rhi he motor se
(2) 1400/ 2800 RPM ki gear box motor
(3) 0.75/1 HP
(4) any2wire ke beech ka resistance 31.5 he
(5) 3 phase motor he

Problem :
(1) kis voltage { 220/440} prr chal rhi he wo pta nahi chal rha
(2) connection kaise hoonge ?

Please reply

[kapilkumargupta]

in low speed motor is running by supplying power to only one terminals of the motor coils in the power circuit 😂😂😂😂

[youngken]

Can the torque be the same in both speeds?

[pareshpatel]

Aux Contact K2 connected to K3 coil should be NO, should not be NC as shown in your schematic.

[farooq]

Sir, How can I run two speed motor in star connection. Please send me wirnig diagram

[JC]

Please advise the following situation:
a three phase 2 speed motor, 6 leads, low speed=only u1 v1 w1, high speed=only u2 v2 w2

[sainanda]

Hi about electricity,
Good video but I need one clarification, in control wiring diagram you mentioned that K2 NC in series with K3, while explaining high speed mode if we press S2 K2 will engage that time K2 NC become NO then K3 will not engage.
Please clarify me whether it is NC or NO
Thank you
