torque speed curves ball mill


equal at this speed Change in speed is achieved by varying the steady state motor speed torque curve so that motor torque equals the load torque at the new desired speed In the figure shown below when the motor parameters are adjusted to provide speed torque curve 1 drive runs at the desired speedω m 1 Speed is changed to ω m 2

Developing a Better Understanding of Actuator Torque

 · Actuator torque is the quantity of torque that an actuator is capable of generating — a critical aspect of the rating specifications for any type of actuator Torque ratings will determine the type of applications in which a specific actuator can be used And when sizing an actuator it is important to give consideration to all of the factors
