GENERAL INFORMATION<br />
Brush Type Synchronous Motor<br />
Brush type (slip ring) motors have<br />
stators similar to squirrel-cage induction<br />
motors and most have rotors with DC slipring<br />
<strong>circuit</strong>s which must be energized for<br />
normal operation. They have two basic<br />
switching functions. The first is the energizing<br />
of the stator to produce breakaway<br />
torque and acceleration to synchronizing<br />
speed. The second is the energizing of the<br />
DC rotor field at optimum speed and rotor<br />
stator pole relationship.<br />

Motor Field Excitation – Brush Type<br />
For brush type motors, DC power for the<br />
field <strong>circuit</strong> is required. This DC power<br />
may be obtained from plant buses, direct<br />
drive DC generators or individual MG sets.<br />
An alternative to the above is a factory<br />
installed static power exciter which may<br />
be supplied with the field application panel.<br />
This unit may be a “constant potential”<br />
exciter with silicon diodes and transformer<br />
with adjustable taps or an “adjustable<br />
potential” exciter with SCRs which has<br />
its voltage output adjustable via a door<br />
mounted potentiometer.<br />

Chronology:<br />
Synchronous control was introduced<br />
in 1947 at Buffalo General Control. The<br />
product moved with General Control to<br />
Asheville, NC in 1978 where it is currently<br />
manufactured.<br />
