NCT SYNCHRONOUS AND ASYNCHRONOUS
SERVO DRIVES AND SERVO MOTORS
8
Synchronous
servo motors
NCT synchronous servo motors are available in 1 Nm -75
Nm torque range with three flange sizes. The shaft design
and connecting main dimensions are compatible with similar
sized motors of several Japanese manufacturers.
Asynchronous
spindle motors
High-speed asynchronous motors are primarily used for driv-
ing spindles of machine tools, and are available with through-
bored shaft and up to 15000-rpm speed. Air- or liquid
cooling is also available depending on size and construc-
tion.
Torque motors
The TORQUE motors can rotate or tilt a rotary table or milling
head directly, without inserting any drive mechanism. These
motors can produce extremely high torques constantly be-
cause of high intensity liquid cooling.
BUILT-IN
SPINDLES
MOTORS
- Higher dynamics because of smaller inertial mass, lower
loss, lower current drain
- Better workpiece geometry thanks to the lack of deformation
caused by belt tension
- Higher lifetime, better surface geometry on workpiece and
higher tool insert life thanks to much lower vibration level
- Better workpiece geometrical and repeating accuracy,
longer lifetime of bearing thanks to lower thermal deforma-
tion because of high intensity liquid cooling
- Long bearing lifetime
- Low noise level
These are the advantages of lathe built-in spindles compared
to conventional belt drive. The liquid-cooled lathe built-in
motor spindles are available in two center line sizes and sev-
eral spindle dimensions.
