locked rotor torque
locked rotor torque
(OP)
I hope someone can help me determine the locked rotor torque for a 110 volt AC, Capacitor-Start, 1/2 HP, single phase motor.
If anyone has a structural problem I may be able to help!
Looking forward to your help,
Baz2

RE: locked rotor torque
Then you need to also more accurately identify the motor. Cap-Start / Induction-Run or Cap-Start / Cap-Run? It makes a big difference.
Peak starting torque, caps in the circuit, with a Cap-Start / Induction-Run motor can be as high as 350% FLT at zero speed. With a Cap-Start / Cap-Run it can be 190-200% FLT at zero speed. Peak running torque, after the start switch is closed, is around 240-250% on both designs.

I have a condition where I have to accelerate a 350 Lb. load from rest to a velocity of 4 inches per sec. I need the LRT to determine the acceleration of the load.

RE: locked rotor torque
The only way to get the LRT of the specific motor that you are looking at, is to get it from the manufacturer or the manufacturers agent.
The LRT for induction motors varies over a wide range (greater than 2 : 1) for motors that appear to be basically the same.
