SIMOTICS M-1FE2 built-in motors
The SIMOTICS M-1FE built-in motors are water-cooled synchronous motors that are supplied as stator and rotor components. When the stator and rotor have been mounted to the spindle in the spindle box, a complete spindle unit is created.
Benefits
ENG_520673.XML
- Compact and rigid spindle design
- Optimum heat dissipation through water cooling for optimum power density and precision
- Broad portfolio for almost all spindle sizes and machining tasks: Maximum speeds up to 40000 r/min, torques up to 1530 Nm in S1 operation
- High dynamic response for maximum productivity due to permanent-magnet rotors with low inertia
- Low rotor temperatures, especially in the low speed range, and low power loss in the rotor, resulting in reduced bearing temperature rise/spindle expansion
- The stator and rotor are machined ready for installation to
facilitate quick and simple installation
- Highest accuracy and surface quality on the workpiece due to smooth, accurate spindle motion over the entire speed range
- Large rotor inner bore – advantage for spindle stiffness and
ejector rod guide for automatic turning machines
- Compatible system of SINUMERIK, SINAMICS S120 and
motor, therefore fast commissioning is ensured
Application
ENG_520674.XML
The water-cooled SIMOTICS M-1FE built-in motors are used in combination with the SINAMICS S120 drive system for applications that require the highest quality of machining, accuracy and running smoothness, as well as very short acceleration times.
There are two main versions of SIMOTICS M-1FE built-in motors available:
- High-Torque series
6-pole/8-pole and 16-pole synchronous motors are available that have been developed for turning and grinding machines with moderate maximum speeds.
These motors are characterized by a very high torque utilization. The speed control range (nn : nmax) here is approximately 1:2 to 1:4.
- High-Speed series
This series has 4-pole synchronous motors for milling applications.
These motors are optimized for high maximum speeds
and a speed control range of up to 1:6.
Design
ENG_520675.XML
The SIMOTICS M-1FE built-in motor comprises:
- A laminated, permanent-magnet rotor, which, as an option, can be designed with a sleeve for simple mounting and removal.
- A wound stator core with cooling jacket and encapsulated winding overhang
- Free cable ends, length 0.5 m, 1.5 m and 3.5 m
- Two integrated Pt1000 temperature sensors (of which 1 is reserve), optionally with full or universal protection
- A cooling jacket in which the stator has been inserted.
Rotor with sleeve
Torque is transmitted to the spindle mechanically with zerobacklash using a cylindrical stepped press fit. The rotor is mounted on the spindle by thermal shrinking.
The rotor with sleeve is pre-balanced and can be removed and subsequently remounted. The bond can be released by pressure-oil injection without affecting the joint surfaces.
Rotor without sleeve
Torque is transmitted to the spindle mechanically with zero-backlash using a cylindrical stepped press fit. The rotor is mounted on the spindle by thermal shrinking.
Removal of the rotor is not possible with this type of mounting. Rotors without sleeves are not pre-balanced.
