Summary
In this publication, we have shown that the application of AC drive
technology to various types of AC elevator motors must rely on a
thorough understanding of the clear advantages and tradeoffs, in
order to make the very best possible choices for AC drives and
motors. Our discussion has included examination of tradeoffs or
possible drawbacks including the potential for increased harmonic
distortion, radio frequency interference, and other issues that
must be addressed in order to use AC technology successfully.
Comparison of AC and DC motor and drive technology does not result
in a clear-cut “winning” technology to be applied universally.
Rather, we have shown that each technology has unique advantages
and disadvantages. We have tried to arm the reader with as many
facts as possible, given the limitations of the size of this
document. As technology evolves, we will endeavor to continue to
pass along as much information as possible to benefit our
customers.
Recognize that AC drives have an inherent delay in starting, which
may affect overall elevator performance time. Unlike DC
applications, where the motor field is energized at all times, in
AC applications, the motor is energized (via power contactor) on
demand. Sufficient time must be allowed for magnetic flux to build
within the motor before the brake can be lifted and the elevator
car operated. Delay time may vary from 200 milliseconds to over one
second, depending on motor characteristics. Therefore, all other
factors being the same, the AC motor and drive must tolerate a
delay on start which does not exist with DC motors and drives.
