3.2 Spindle motors
• The spindle motor must be provided with enough space so that it is cooled effectively by
its cooling fan. Especially, there must be a 100 mm or more space between the no-load
side of the spindle motor and a nearest machine part. If the spindle motor were not
cooled enough, a motor overheat protector could operate even if the spindle motor runs
at the rated load.
• The bed, foundation or mount on which the spindle motor is installed must be rigid
enough. Otherwise the bed could vibrate due to the weight of the motor and the
dynamic load from the machine.
• The installation site must be free of excessive dust or iron particles. As the air forced by
the built-in cooling fan passes along the motor core, it could be blocked by any accumu-
lated dust in the way. If the spindle motor were not cooled enough, a motor overheat
protector could operate even if the spindle motor runs at the rated load.
