Compact Drive for PMAC Sensorless Control

AC650S Series

0.25kW - 7.5kW

Energy savings and compact size

The AC650S Compact PMAC drive delivers impressive performance and machines when compared to standard
series features an advanced sesnorless high energy efficiency, which in turn induction motors of the same size.
control algorithm for controlling leads to lower energy usage than with In some cases PMAC motors can be

Extremely compact solution for smaller machines

Parker PMAC motors have high power
density, and are up to 75 % smaller than
the same power induction motors, which
enables you to make ultra-compact machines.
Up to 75% smaller
Furthermore, compared to induction motors, Up to 75% smaller
PMAC motors are available with a very
economical brake option and have no need
for force ventilation.
