This Eagle EL-550 electric motor for industrial sewing machines runs quietly and is completely silent when in the stopped position. Since its circuitry is designed for energy efficiency, the servo motor uses less electricity than a standard clutch model. You can use it without a clutch or brake disc. The motor includes a belt guard, pulley, and the necessary mounting hardware. This 550-watt, 3/4 HP, 110-volt motor weighs 15.5 pounds.
