PM Synchronizer Motor with Housing
Figure 7-4 shows a UG-8 Dial governor with a permanent magnet synchronizer
motor (speed setting motor) and a shutdown solenoid, enclosed in a
weatherproof housing.
At rest, the permanent magnet motor acts as a brake to resist speed changes
due to vibrations.
The weatherproof housing for the PM synchronizer motor can also be equipped
with a shutdown solenoid. There are several supply voltages available for the
solenoid. Contact Woodward for additional information. A conduit connection and
a pin-type connector are also available.
