INDUCTION MOTOR SOLID-STATE REDUCED
VOLTAGE STARTER (SOFTSTARTER) WITH
SOFTSTOP FEATURE
(PRELIMINARY DATA)
celduc relais
SMCV
can be employed everywhere using a costly and relatively big
variable speed controller is not required (pumps, fans, compressors, conveyors, …).
Its
six thyristor
structure working like a full wave phase angle controller (both positive
and negative cycles are controlled), allows to reduce efficiently the induction motor starting current
as well as the motor starting torque. This
motor starting current reduction
allows to optimize
the mains grid as well as its protections and
avoid having voltage fluctuations
leading to
ambient light variations also called "flicker".
Built to help the user to get his assembly in compliance with the European directives and
standards, this product easy fits in the existing application without any modification of the wiring
field configuration. Thus, the
SMCV
can easily replace an electromechanical star-delta starter
without changing the motor coupling! In a project including a three phase induction motor it can be
implemented like a usual three phase electromechanical contactor. Furthermore, its ability to be
installed inside the delta wiring allows this device to drive
1.73 times more current
than a
standard on line softstarter,
The
SMCV
also have
diagnostic and self-test functions
to inform people involved in the
machine maintenance and
to reduce the cost and the delay to restart the production.

IMPORTANT INFORMATION ABOUT THE DIAGNOSTIC
1-
2-
3-
The device makes a complete diagnostic (mains, load and itself) since it has enough supply voltage (On the mains or on the control side).
The device only checks the presence of the phases and the closing of the solid state switches during the voltage ramps (Softstart and
softstop) and during the full on state period.
The control overrides the diagnostic.
-
If a problem occurs during the control period, the device will close all the solid state switches. If the problem goes on during
the full on state period, the corresponding information will be given to the user according to the table above.
-
Likewise, if a problem occurs during the softstopping period, the device will stop immediately in order to reach the off state
diagnostic period.
On a hard stop (no softstop) and case of driving a large motor, the device may temporary display a problem concerning the mains. This is
due to an important residual voltage across the motor windings (Back EMF generated by the motor rotation and the remaining magnetic
field). This security allows the user to avoid connecting the motor to the mains in bad conditions. This phenomenon can be cancelled by
using the softstop feature that slowly reduces the remanent magnetic field inside the motor. This allows as well to avoid overvoltage
across the solid state switches (increasing the lifetime expectancy of the integrated varistors). Therefore, softstop is recommended even
with high inertia motor loads.
