2. General description
Emotron EMX-D is a speed-controlled drive system spe-
cially designed for driving rotary heat-exchangers. The sys-
tem comprises an enclosed control unit and a motor unit
with worm reduction gear, which are linked by two cables.
The control unit is driven by a single-phase power supply,
230 VAC, 50/60 Hz.
Emotron EMX-D has numerous built-in features making it
ideal for this particular application:
• No initial trimming is required.
• Soft starting/soft stop.
• Electronic motor protection.
• The drive system is designed to suit most types of
control signal.
• The control inputs are galvanically-isolated.
• The operational status of the system can be displayed.
• High efficiency.
Furthermore, the drive system has a built-in linearity
function that gives a linear relationship between the control
signal and the efficiency of the heat exchanger rather than
having the speed of rotation proportional to the control sig-
nal. This provides good conditions for stable
temperature control.
