Product characteristics
Ball screw
The direct-drive ball screw translates the rotation of the motor into a
linear motion.
Internal anti-twist protection
The internal anti-twist protection supports the torque and ensures
that the rotational movement of the rotor is converted into a linear
movement of the spindle.
Neodymium permanent magnets
The magnets installed in the motor are permanent magnets.
Neodymium is a hard magnetic material that enables the precise
and highly dynamic positioning of the motors.
Three-phase stator winding
The three-phase winding in the stator reduces the amount of mate-
rial required while maintaining the same electrical output. All phase
angles are 120°.
Electronic commutation in the servo drive
The commutation of the motor is done electronically. The three coil
turns are supplied from a bridge circuit.
Thermal contacts
A thermal contact LPTC-600 is installed to monitor and measure the
winding temperature and to protect the motor against overheating.
