SYNCHRONOUS MOTOR CONTROL<br />
Brush Type Mark V Solid-State Slipsyn<br />
Class 14-200 Low-Voltage Motor Starters<br />
PRODUCTION DESCRIPTION<br />
Application<br />
Slipsyn magnetic starters provide reliable,<br />
automatic starting of synchronous motors.<br />
Automatic synchronization is provided by<br />
the Mark V Solid-State Field Panel which<br />
assures application of the field at proper<br />
motor speed, and at a favorable angular<br />
position of stator and rotor poles. As a<br />
result, line disturbance resulting from<br />
synchronization is reduced and effective<br />
motor pull-in torque is increased. Application<br />
of DC power to motor field windings<br />
is accomplished without mechanically<br />
moving parts, and the device features a<br />
”soft-turn on“ <strong>circuit</strong> when applying DC<br />
voltage to the motor field.<br />
The solid-state Mark V Slipsyn controller<br />
will provide the following protective<br />
functions:<br />
A. Locked rotor protection<br />
B. Incomplete sequence<br />
C. Failure to synchronize<br />
D. Fuse failure (Mark V)<br />
E. Pull out protection<br />
F. DC current failure protection<br />
The cabinet will contain the following:<br />
1 – Primary starter full voltage or reduced<br />
voltage<br />
1 – Ammeter shunt (when required)<br />
