Description of the motors
Highlights and benefits
Overview
1FT7 synchronous motors are permanent-magnet motors with very compact dimensions.
The motors can be quickly and easily mounted due to the well-proven cross-profile for shaft
heights 36 to 100.
The 1FT7 motors meet the highest demands for 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 are optimized for operation on our completely
digital drive and control systems.

The cooling methods natural cooling, forced ventilation, or water cooling are available.
Whereas in natural cooling the thermal losses are dissipated through the surface into the
ambient air, in forced ventilation a mounted fan provides a constant air flow, which forcibly
dissipates the thermal losses. Maximum cooling and, therefore, maximum power can be
achieved using water cooling.
