1.3 Product Concept
1.3.1 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
).
Installation is 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.
