Matching Motor Torque To Your Load EC&M

You must consider steadystate, acceleration, and starting torque to ensure the lowest motor operating costs. There''s torque, and then there''s torque. There''s torque, as required by your load, and torque, as available at your motor output. Both are critically important when you''re selecting and designing a drive for maximum efficiency.There are three major appliion aspects of motor torque
