Overview
SIMOTICS M-1PH808 spindle motor with forced ventilation
SIMOTICS M-1PH8 motors are compact squirrel-cage asynchro-
nous motors with degree of protection IP55. SIMOTICS M-1PH8
motors have been designed specifically for use in conjunction
with the SINAMICS S120 drive system. Depending on the control
requirements, appropriate encoder systems are available for the
motors for sensing the motor speed and indirect position.
The SIMOTICS M-1PH8 spindle motors are perfectly adapted to
the SINAMICS S120 Combi drive system.
■
Application
•
Main spindles for standard milling and turning machines
•
Driven tools for standard turning machines
■
Benefits
7
Maximum power over an extremely wide speed range as a
result of intelligent winding design and optimized field-weak-
ening and heat dissipation concept
7
Very fast spindle acceleration rates and maximum cutting
forces thanks to special lamination structure and high over-
load factor
7
Long-lasting motor bearings for high radial forces with belt
drives
7
High degree of protection, including motor fan
