High-inertia loads often cause problems in motor control and starting current. However, traditional starting methods, such as autotransformer, part winding and wye-delta, are difficult to apply for this type of loads. Their fundamental limitation lies on the fact that their current and torque are confined to fixed selections. Thus, a solid-state controller is recommended as one of the most cost-effective starting methods for this application. It features the ability to more fully regulate the parameters for high-inertia load situations., Reduced voltage starting has been used with induction motors for many years to lessen the electrical and mechanical strains that result from across-the-line starting. High-inertia loads, such as centrifuges, mixers, [...]
