Permanent magnet Cycletrol® DC Motors
MOC-1 Motor Overload Control
Graham Transmissions’ permanent
magnet DC motors are optimized for
rapid cycling use with Cycletrol
Series DC controls. All motors are instock for prompt delivery.
The MOC-1 monitors motor load and
provides a latched “alarm” contact if
an overload occurs. An adjustable
time delay allows the MOC-1 to
ignore normal acceleration currents
without nuisance tripping. The
MOC-1 is frequently used to shut
down an overloaded system before
motor or machine damage can
occur.
