Siemens motor/drive package offers matched Simotics motor and Sinamics drive.
Siemens released a line of combination motor/drive packages targeted at a variety of heavy-duty industrial motion control applications. The motor and drive combinations are power-matched for 480V high-overload operation through a 20 hp range, with I2T protection from thermal damage. Application macros are provided in the Sinamics G120C drive and the terminals are pre-assigned at the factory and the parameters are automatically set. SIMOTICS SD100 motors are cast-iron with inverter duty ratings in a 4:1 speed range for constant torque and 20:1 speed range for variable torque. Simotics SD100 units are severe-duty TEFC motors that meet NEMA Premium efficiency. Communications selections on these matched motor/drive combinations include RS485 with USS and Modbus protocols. A Profibus variant is also offered.
