Small DC Motors
Connection diagrams are shown above. Care must be taken to ensure that
the dual-voltage shunt field is properly connected.
Some DC motors are equipped with a thermostat inside the motor. This
thermostat has a normally closed (NC) contact which opens if the motor
temperature exceeds design limits due to extended overload operation.
Leads from the thermostat are labeled P1 & P2 and should be connected in
series with the drive “STOP” button (refer to the previous figure).
!
ATTENTION: Ground the machine properly to avoid serious
injury to personnel. Grounding should be in accordance with the
National Electrical Code and consistent with sound local
practices.

Motors with single voltage fields do not have leads F11 & F22. Leads F11 & F22 may be
marked F3 & F4, respectively. Connect on low voltage field connection.
