Q.Is there any way to suppress the temperature rise of stepper motors (including αSTEP)?

The following methods are measures to prevent a temperature rise in the stepper motor.

1. Use high efficiency motors with low heat generation
   The following range of high efficiency motors are available.
   For applications where heat generation is a concern, consider a high efficiency motor.

   RKII Series
   AR Series

2. Reduce operating duty
   Stepper motors tend to generate more heat during operation than during standstill, meaning it is possible to reduce heat generation by lowering operating duty. Operating duty is calculated using the following formula. As a reference, the stepper motor should be used at an operating duty of 50 % or less.

3. Use a mounting plate with good heat conductivity

4. Adjust the operating current
   Heat generation by the stepper motor is proportional to the setting value of the operating current.
   This means heat generation can be controlled by narrowing down the current value.
   However, since the torque also deteriorates with the current value, adjust only when there is a margin of torque.
