21. An electronic apparatus, comprising:
a first electric motor,
a second electric motor disposed adjacent to the first electric motor;
first driver circuitry configured to drive the first electric motor;
second driver circuitry configured to drive the second electric motor;
a temperature sensor configured to detect a temperature of the first electric motor; and
one or more processors configured to:
control the first driver circuitry to drive the first electric motor according to a predetermined voltage signal to cause the first electric motor to stall and generate heat,
control the second driver circuitry to drive the second electric motor according to the predetermined voltage signal to cause the second electric motor to stall and generate heat, and
receive information about the temperature of the first electric motor detected by the temperature sensor while the first electric motor is stalled, and
maintain a temperature of the first electric motor below a threshold temperature value while the first electric motor is stalled based on the information about the temperature of the first electric motor detected by the temperature sensor while the first electric motor is stalled.
