Integration of frequency converter and motor
The Danfoss VLT
®
frequency converter integrated
onto the asynchronous motor gives infinite speed
control in one unit.
The VLT
®
DriveMotor FCM 300 Series is a very
compact alternative to the ordinary solution with VLT
frequency converter and motor as separate units. The
frequency converter is attached instead of the motor
terminal box, and it is no higher than the standard
terminal box, nor wider or longer than the motor (see
chapter 6).
Installation is made extremely easy. Panel space is not
a problem. There is no need for special details on
wiring to meet the EMC directive, since motor cables
are not necessary. The only connections are mains
and control connections.
Factory-set adaption between frequency converter
and motor gives precise and energy efficient control in
addition to eliminating pre-setting on site.
The FC motor can be used in stand alone systems
with traditional control signals, such as start/stop
signals, speed references and closed loop process
control or in multiple drive systems with control
signals distributed by a field bus.
Combination of fieldbus and traditional control signals
and closed loop PID control is possible.
