actual speed. Polyphase AC Motors. Polyphase squirrel-cage ac motors, such as 3 phase motors, are basically constant-speed machines, but some degree of flexibility in operating characteristics results from modifying the rotor slot design. These variations in ac motors produce changes in torque, current, and full-load speed. Evolution and standardization have resulted in four fundamental types of ac motors. AC Motors - Designs A and B.

is required. In high-horsepower industrial sizes, the synchronous motor provides two important functions. First, it is a highly efficient means of converting ac energy to work. Second, it can operate at leading or unity power factor and thereby provide power-factor correction. There are two major types of synchronous motors: nonexcited and direct- current excited. Nonexcited motors. Manufactured in reluctance and hysteresis designs, these motors employ a selfstarting circuit and require no external... (read more)Browse AC Motors Datasheets for Sinotech Motors
