With an output range from 0.06 kW to 1250 kW, low-voltage motors are available for the widest range of requirements and applications that are harmonized and coordinated with the MICROMASTER and SINAMICS frequency inverters. In addition to energy-saving motors and explosion-proof motors, there are also sector and customer-specific motors such as smoke extraction motors. The table shows an overview of the technical features of these motors. You will find the available product range with ordering data, technical data and detailed explanations in Catalog D 81.1 “Low-Voltage Motors – IEC Squirrel-Cage Motors – Frame Sizes 56 to 450” and on the Internet under:
