SYNCHRONOUS MOTOR CONTROL
Brushless Type Mark V Solid-State Slipsyn
Class 14-100 Field Application Panel
PRODUCT DESCRIPTION
Slipsyn Automatic Field Application Panel with Static Exciter
Automatic Field Application Control
The field application panel provides
Slipsyn automatic field application identical
to that in complete synchronous motor
starters. It is designed for use in conjunction
with a primary line closing device
such as a circuit breaker or a linestarter.
Automatic synchronization is provided by
the Mark V Solid-State Field Panel which
assures application of the field at proper
motor speed and at a favorable angular
position of stator and rotor poles. As a
result, line disturbance resulting from
synchronization is reduced and effective
motor pull-in torque is increased. Application
of DC power to motor field windings
is accomplished without mechanically
moving parts, and the device features a
”soft-turn-on“ circuit when applying DC
field voltage to the motor field.
This unit also comes standard with a VAR/
PF/DC field current regulator. The VAR
regulator controls the AC reactive current
flow out of the motor during varying load
GENERAL INFORMATION
conditions by varying the motor field
excitation. The PF regulator controls the
motor power factor under varying load
conditions by varying the motor field excitation.
The DC field current regulator compensates
for the motor field resistance as
the motor field heats up by increasing the
motor field voltage.➊
The solid-state Mark V Slipsyn controller
will provide the following protective
functions:
A. Locked rotor protection
B. Incomplete sequence
C. Failure to synchronize
D. Fuse failure (Mark V)
E. Pull out protection
F. DC current failure protection
This control is available in a NEMA 1 floor
mounted enclosure or an AMPGARD type
cell construction. In both designs, a hinged
front door with externally ventilated heat
sinks will be provided.
