Many businesses rely on the excellence of Bosch Rexroth to meet their automation goals. The company’s state-of-the-art 2AD motors are notable for their varying sizes and speeds. They are especially suited for applications like reshaping machines and printing machines.
The 2AD100C-B05OA2-AS11-A2N1 is one of the high-performance asynchronous motors in the 2AD series designed and manufactured by Bosch Rexroth. It is built to attain a nominal speed of 1,500 revolutions per minute but can reach a maximum speed of 9,000 revolutions per minute. Its efficient operation is promoted by its surface cooling system comprising an axial blower that generates an air stream from side A to side B. The air currents from this blower are guided through air baffles across the motor’s surface. It uses a squirrel-cage rotor with a moment of inertia of 0.021 kgm2 for converting electrical energy into mechanical energy. This rotor can withstand high mechanical stress and requires minimal maintenance due to its robust construction.
An electrically engaged holding brake is integrated into the design of the 2AD100C-B05OA2-AS11-A2N1. It is a locking element of the main spindle that prevents unintentional movement when the motor is standing still or when the drive enable is switched off. The two NTC thermistors in the windings of the 2AD model monitor its temperature to prevent irreversible damage due to thermal overload. Its standard bearing consists of deep-groove ball bearings designed to absorb low to medium radial and axial forces. The bearing remains lubricated throughout its service life of about 20,000 operating hours, reducing the risk of downtime. Ideally, the maximum recommended installation height for the motor is 1,000m above mean sea level.
