Dear sir, in crane application during hoisting the rpm is low but lift full load. And during full load hanging condition the hoist run upwards without freefall. Plz explain
Yes it will work fine. We can call it as induction motor. It will also provide High starting torque because we know condition for high starting torque..Rotor resistance should be equal to rotor reactance. R=Xl. Now let consider we have starting frequency from 5Hz, and inductance of coil is 1 Henry, Resistance of coil is 31.4 ohms. Reactance Xl = 2pi fL= 2*3.14*5*1= 31.4ohms. Here resistance will equal to reactance 31.4=31.4so it will provide high starting torque. So it will provide smooth starting and high torque....
Sir please explain DG set GCB fail to close alram and explain your thoughts to help us and create video DG operation iam working on PCC department and I face these problems 🧑🔧@abhishek jhosi sir
Bahut achhese samjaya hai aapne sir
Dear Abhishek Rotor can be in Short condition via GRR or LRS and Run motor in vector control it will provide high starting Torque initially by MVD
Sir GRR and LRS ke bare me explain kijiye.
Excellent explained Bhai thanks
Dear sir, VFD se not only speed and smooth starting but torque bhi control kiya jata hai... In vector control mode.
Awesome explanation..
Sundar prachestha sir thanks
Why is PT secondary never short-circuited????
What is cathodic protection system?
Please take lecture on Plc and plcs used in industries
Sir yadi vfd ki life jyada old ho gayi hai aur vo 50 hz pe chal rhi hai to kya vfd ke jagah soft starter use kar sakte ??
Sir G
Yha sugar mill m slipring motor ko vfd se chalaya jata hai
Ur vfd ke saat DBR use Kiya jata hai
Please pura process btaye ki y kese hota hai❤
But cant high starting torque be achieved by VFD's also nowadays?
Sir squirel cage induction motor main resistance type stator q use karte hain,
Sir ht line ka fuse selection kaise krte hai iss pr ek video banana pls
Great sir good information ❤❤🇵🇰🇮🇳
Good sir, MV VFD ki video banaye plz
Boiler ID fans having Slip ring motor planning to place vfd drive . What about your opinion?
High starting torque k liye bhi drive use hota hai sir
Sir grr and lrs ke bare me batey
Sir kindly explain why insulated bearing used in VFD drive motor?
👍👍👍👍👍
Why are used star delta
Dear sir, in crane application during hoisting the rpm is low but lift full load. And during full load hanging condition the hoist run upwards without freefall. Plz explain
Can we start slipring motor on soft startor drive method
Line tester jab wooden table pe khade ho kar line test karte hai tab bhi kaise work karta hai ?
❤❤❤❤
Lift me konsa motor youse aathaahe
Sir crane main konsi VFD work karti hai
Nice
But we have run a slip ring motor through a vfd after short its slipring side and it is working fine
Yes it will work fine.
We can call it as induction motor.
It will also provide High starting torque because we know condition for high starting torque..Rotor resistance should be equal to rotor reactance. R=Xl.
Now let consider we have starting frequency from 5Hz, and inductance of coil is 1 Henry, Resistance of coil is 31.4 ohms.
Reactance
Xl = 2pi fL= 2*3.14*5*1= 31.4ohms.
Here resistance will equal to reactance 31.4=31.4so it will provide high starting torque.
So it will provide smooth starting and high torque....

Sir please explain DG set GCB fail to close alram and explain your thoughts to help us and create video DG operation iam working on PCC department and I face these problems 🧑🔧@abhishek jhosi sir
I think please check the closing ckt and UV relay or timer and their connections it's my opinion
