Thyristor – Controlied Motor Drives
Thyristor – Controlied Motor Drives Several factors have served to boost the use of thyristor-controlled motor drives, notably the high efficiency of thyristor converters (95-97%), the relatively small size, mass and time lag of thyristors, and the small power needed for the operation of thyristor controllers. A further advantage is that thyristor control offers a […]

The Selection of Motor Design and Enclosure
The Selection of Motor Design and Enclosure The selection of a motor design (d.c., induction, synchronous) is a relatively simple task in the case of a continuous, unvarying load. This application does not call for speed control, so the best choice is a synchronous motor. The point is that a synchronous motor is started in […]
