Control eBook: The Complete Guide to 3-phase Motor Wiring
In this eBook, created in cooperation with SEW Eurodrive, we explain the AC voltage system as it applies to motors.
eBook Overview
Alternating current (AC) electricity is one of the two prevailing systems that drive the world of electrical motion, both for consumer and for industrial devices. AC electricity is the common go-to method of powering large industrial motors.
For large industrial systems with continuous motion, 3-phase electricity is the most common. Between the various standards and voltage levels, however, it can be difficult to identify the correct motor for every application.
In this eBook, created in cooperation with SEW Eurodrive, we explain the AC voltage system as it applies to motors. We begin with a comparison of single-phase (1-phase) and three-phase (3-phase) voltage applications but then illustrate the many ways in which 3-phase motors can be wired to accept high or low voltages, depending on the type of motor
desired.
Finally, we discuss the important concept of ‘neutral’ in a 3-phase system, explaining why it exists in a supply, but not in a motor load wiring scenario.
