A motor spindle generally consists of the following components:
S
Spindle box
S
Spindle with bearings
S
Cooling system
The spindle manufacturer is responsible for designing the bearings,
lubrication and cooling.
S
Build–in motor
– 4–pole series (especially suitable for high speeds)
– 6–pole series (especially suitable for high torque)
– A VP module (VPM) is required, depending on the EMF (rotor
voltage) (VPM: Voltage Protection Module)
– Maximum speed:
