SIMOTICS M – Main motors
1PH8 for SINAMICS S120 for cranes
■
Overview
1PH8 three-phase motor, shaft height 355
The innovations in the field of modern crane installations place
higher and higher demands on compact asynchronous motors.
The compact asynchronous motor 1PH8 of shaft height 355
covers the increased performance requirements, e.g. for
intermittent duty S3-40 % with up to 1.97 MW.
This motor serie is a converter solution which has been
developed for use in conjunction with the SINAMICS S120
drive system. The 1PH8 asynchronous motors have the
following features:
•
Forced ventilated asynchronous motors with squirrel-cage
rotor with IP55 degree of protection. The motors are ventilated
as standard by a radial, externally mounted fan unit. With the
"enhanced corrosion protection" option, the motors can also
be installed outdoors.
•
Forced ventilated asynchronous motors with squirrel-cage
rotor with IP23 degree of protection. These motors are also
ventilated as standard by a radial, externally mounted fan
unit.
These motors are particularly suitable for installation in
power houses.
■
Benefits
•
High power density with small motor dimensions
•
Wide speed control ranges
•
Speed down to zero without reducing the torque (constant
torque characteristic)
•
High rotational accuracy, even at the lowest speeds
•
Fitted as standard with regreasing unit and insulated
NDE bearing
•
Optimized for converter-fed operation on SINAMICS
•
Large selection of options
