Special operating conditions
Operating under light-load conditions
If a machine is operated continuously or over a long period under light-load conditions with
approximately half rated current or less, damage will occur. High brush wear or problems with
the commutator may result. More details are available in the chapter titled "Faults".
If the motor is to be operated continuously under light-load conditions, consult the
manufacturer.
Loading at standstill
Load stationary DC motors with armature current only for short periods so as to protect the
commutator against damage. Obtain the permissible current and time values for loading at
standstill from the manufacturer.
