1.1 Features
Overview
1FT7 synchronous motors are permanent magnet synchronous motors with very compact
dimensions. Quick, easy mounting of the motors is possible due to the well proven cross-
profile.
The 1FT7 motors satisfy the highest demands in terms of dynamic response and speed
setting range, including field weakening, radial eccentricity, and positioning accuracy. They
are equipped with state-of-the-art encoder technology and optimized for operation on our
completely digitally designed drive and control systems.

In terms of cooling methods, natural cooling, forced ventilation, or liquid cooling are available
for selection. While the heat loss created during natural cooling is discharged over the
surface into the ambient air, during forced ventilation a mounted-on fan provides a constant
airflow, which forcibly dissipates the heat loss. Maximum cooling and, therefore, maximum
power can be achieved by using liquid cooling.
