Properties
Overview
Air-cooled 1PH7 motors are rugged and low-maintenance 4-pole induction motors with
squirrel-cage rotors. A fan for providing forced ventilation is mounted axially on the rear side
of the motor. The air flow direction is as standard from the motor shaft (DE) to the rear of the
motor (NDE) in order to keep the motor heat loss away from the machine. The reverse
direction of air flow can be ordered as an option.
The motors are equipped with an integrated encoder system for sensing the motor speed
and indirect position. For machine tools, the encoder system is capable of C-axis operation
as standard - i.e. an additional encoder is not required for C-axis operation.
Shaft heights 100 to 160
Shaft heights 180 and 225
Benefits
● Short overall length of motor
● Minimized disturbing contour thanks to the integrated terminal box (shaft heights
100 to 160)
● Maximum speeds up to 9000 rpm (option: 12000 rpm)
● Full rated torque is continuously available, even at standstill
● Optimally adapted to the SINAMICS S120 power graduations
