What is torque calculation: Definition and 3 Discussions

Direct torque control (DTC) is one method used in variable-frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors. This involves calculating an estimate of the motor's magnetic flux and torque based on the measured voltage and current of the motor.

    Calculating Torque on this Square

    So I started by just figuring out what forces are going to have torque. I know the one heading straight down from the pivot won’t have any and the one going at an angle from the pivot won’t be included in the net torque since it’s at the pivot. The rest of the forces have torque and they are...

    Motor Sizing for Wheel Endurance Testing

    I am working with a wheel endurance testing application. I am trying to size a motor for the system. Basically, I have a drum which has to be rotated by the motor. I have different size wheels that I have to test. The motor is supposed to rotate the drum and then the wheel is pushed onto the...

    Calculate drive torque for rotating large drums

    Hi, I'm new to the forum so thanks in advance for any help. We would like to make a fixture for rotating large drums in a paint booth. I would like to know how to calculate the torque required at the trunnions to rotate the drum using two drive trunnions (with 2 idler trunnions). I've...
