FCM Series
■ 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
widerorlongerthanthemotor(seechapter6).
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.
