The three-phase motor series SIMOTICS N-compact covers outputs up to 1250 kW (at 50 Hz) in the non-standard range. A number of technical features provide this motor series with ruggedness and long service life and ensure the highest level of availability, for example, motor protection with PTC thermistors with 6 embedded temperature sensors for alarm and tripping is standard.
SIMOTICS N-compact motors are also characterized by their high output for small frame size. The consequence of this is an extremely compact design that can be used to save space in a number of industrial applications.
SIMOTICS N-compact motors are not only optimized in terms of their construction, but also in terms of their efficiency, so they also contribute towards lower energy consumption.
Apart from mains-fed operation, the SIMOTICS N-compact motors are also specially designed for converter-fed operation, for example, insulated bearings are used at the non-drive-end NDE for converter-fed operation as standard to prevent damage being caused as a result of bearing currents. In combination with frequency converters from the SINAMICS and SIMOVERT MASTERDRIVES product series, they build up perfectly interacting drive systems for variable-speed drive applications.
