SIRIUS 3R Reduced Voltage While it is common to turn motors on and off instantaneously,
Starters this abrupt transition results in power surges and mechanical
shock that may need to be avoided, especially when larger
motors are involved. Reduced voltage starters, however, apply
voltage more gradually. As a result, the motor experiences
reduced inrush current and speed is accelerated gradually. There
are several types of reduced voltage starters, including solid
state reduced voltage starters, called soft starters.
The SIRIUS 3R modular system of components includes SIRIUS
3RW30 and 3RW40 soft starters for standard applications, and
SIRIUS 3RW44 soft starters for high feature applications.

AC Drives Although motor starters can control an AC motor for constant
speed applications, many applications require control of motor
speed. An AC drive is an electronic device that, in addition to
controlling motor speed, may control other quantities such as
torque, but that depends upon the capabilities of the drive and
the needs of the application. Because the type of motor being
controlled is often an AC induction motor and the speed of
this motor is dependent upon the frequency of the AC power
applied, an AC drive is often referred to as a variable frequency
drive, or VFD for short.
Because AC motors are available in a range of ratings and types
and application requirements vary widely, Siemens offers a
broad range of AC drives and related products. These drives are
divided into two broad classes, low voltage and medium voltage.
