Drives with small motors

Abstract

Small electric motors are devices used in drives in the power range up to about 103 W. In this book the distinction found elsewhere between small and miniature motors is not made. Even the 103W value given above does not represent an absolute limit. For example, brushless direct current (DC) motors are now manufactured with power ratings up to 2 x 105 W. There is a wide variety of small motors, each design being tailored to meet the special demands made by the driven device. In this way these motors are in contrast with high powered motors, particularly 3-phase induction motors, which are largely built to standard specifications.
