SIMOTICS FD Flexible Duty motors

SIMOTICS FD motors optimized for converter operation are the basis for a cost-effective overall system comprising motor and converter with high power density. The cast iron enclosure makes the motor rugged and durable. When operated as variable-speed drive, SIMOTICS FD motors are especially efficient. The combination of SIMOTICS FD motors and SINAMICS low-voltage converters is especially cost effective, as motor and converter are precisely harmonized and coordinated with one another. The motors are based on a leading-edge modular system, which provides the optimum motor to address the widest range of requirements. They are available with different cooling methods – extending all the way to water cooling.
