Product Description

The 1MR160B-A055 is a motor rotor. It is used for Bosch 1MB series asynchronous motors. The design of the rotor has a finished step interference fit. The inside diameter of the 1MR160B-A055 is 55 millimeters. The approximate shipping weight of the motor rotor is 5.3 kilograms. 1MB motors that are based on the 1MR160B-A055 have the following specifications: 16 Nm rated torque, 3000 RPM rated speed, 5 kilowatts rated power output, 36 Amps rated current output, 138 Volts rated voltage, 78.4 Volts maximum current and 12000 RPM maximum speed. The moment of inertia of the 1MR160B-A055 rotor is 0.008 kg m². The heat that is dissipated inside the 1MB motors is absorbed by a liquid coolant. The coolant absorbs most of the heat dissipated by the stator and a major part of the heat dissipated inside the rotor.

During storage, the 1MR160B-A055 should be protected from moisture, dust and vibrations. The allowed ambient temperature range for motor storage is -20 to 80 degrees Celsius. The allowed ambient temperature range for motor operation is 0 to 40 degrees Celsius. The maximum permitted installation site altitude that does not lead to output derating is 1000 meters. Operation of 1MB motors above 55 degrees Celsius temperature and above 5000 meters altitude is not permitted. The respective utilization factors have to be multiplied if both the altitude and temperature exceed permitted ranges simultaneously. The information for utilization depending on the site altitude and ambient temperature using the specified liquid coolant do not apply solely to the motor, but to the entire drive system, consisting of the motor, drive controller and mains supply. 1MB motors and their components should be installed by trained professionals. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
