stepper motor driver over‐heating
Ventilation and cooling accommodations are essential – failure to provide adequate airflow will affect the stepper motor driver’s performance and will shorten the life of the driver Keep driver temperatures below 60 degrees Celsius.
To maintain good airflow, use fans, heat sink material, and base plates, so not to exceed the maximum temperature rating of the stepper motors, drivers or controllers. Be mindful of temperatures inside cabinets and enclosures where stepper drivers may be mounted.
Note: Painted surfaces do not make good heat sink material for stepper motor drivers and controllers. Also, be certain that the environment is free from dust and debris that can clog a fan‐cooled system.
