Abstract: The brushless motor includes a coil array, a magnet array, a magnetic sensor, a drive control circuit for driving the coil array, and a temperature sensor for detecting a detection target temperature associated with either the coil temperature or the driving element temperature. The drive control circuit reduces the effective value of driving voltage supplied to the coil array when coil temperature detected by the temperature sensor has exceeded a prescribed threshold value.

Abstract: A spread range control apparatus of the present invention controls a clock generator, which generates a spread spectrum clock based on setting of spread data, so as to regulate a spread range of the spread spectrum clock. The spread range control apparatus includes: a loading quantity detection module that detects a loading quantity of a loading device, which is driven in response to a clock output from the clock generator; and a spread range setting module that sets spread data, which represents a spread range corresponding to the loading quantity detected by the loading quantity detection module, in the clock generator. This arrangement effectively protects a device having operations controlled in response to a clock from adverse effects possibly arising due to spread of the clock.
