Typically systems and motors are designed to operate with a right hand rotating field.

• A. False
• B. True
• C. Not always true
• D. Typically yes; right hand rotating field is standard

Answer: (D)

The main idea is that a three-phase stator current creates a rotating magnetic field, and the direction of that rotation is set by the phase sequence. When the phase order is the normal positive sequence, the resulting field rotates in the right-hand sense. This convention is what most systems and motors are designed around because it provides a consistent torque direction and predictable starting and control behavior. If the phase order were changed, the rotating field would turn the opposite way, reversing motor direction, but that isn’t the standard design expectation. So, typical systems and motors operate with a right-hand rotating field.
