1. A cart comprising:
a driving wheel;
a motor configured to rotate the driving wheel;
a motor drive circuit configured to drive the motor;
a motor brake electronic circuit configured to electrically brake the motor;
a control device configured to control the motor via the motor drive circuit and the motor brake electronic circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed; and
a temperature sensor configured to detect a temperature of the motor brake electronic circuit,
wherein
when the upper limit travelling speed is a first upper limit travelling speed and the temperature detected by the temperature sensor exceeds a first predetermined temperature, the control device is configured to change the upper limit travelling speed to a second upper limit travelling speed lower than the first upper limit travelling speed.
