Controlled-Torque Starting of Textile Machinery

Control of the starting torque of textile machinery drives has become an important factor in the effective performance of textile machinery. Increased operating speeds to achieve greater production requires more precise acceleration of machine components to ensure efficient operation. Controlled acceleration also eliminates premature failure of the machine elements. Many factors must be considered in determining the optimum system for a given machine. Some of the applications in which controlled-torque systems could be used advantageously and some of the controlled-torque systems that are available are investigated.
