Abstract

Various types of electric variable speed motor drives are available for variable torque loads, typically pumps and fans. Constant torque loads present a more arduous duty to the drive. The author covers the concept of the variable speed synchronous motor drive, addressing its operation, system performance and benefits, and some application considerations. An example of a 2000 hp Banbury mixer drive is presented. A Banbury mixer is a heavy-duty batch mixer, with two counterrotating rotors, for doughy material, and is used in the plastics and rubber industries.<>
