A step motor typically reaches maximum temperature after 30 to 45 min of operation.
Running the motor for one minute and then idling for one minute results in a 50% duty
cycle. Running the motor for five minutes on and five minutes off also results in 50% duty.
One hour on and one hour off results in 100% duty because the motor will reach full and possibly
excessive temperature during the first hour of use.
Note
National Instruments tested the NI ISM-7413 in a 40 °C (104 °F)
environment with the motor mounted to an aluminum plate sized to provide a surface
area consistent with the motor power dissipation. Your results might vary.
