1MR240F-A072

Product Description

The 1MR240F-A072 is a rotor for motors from the Bosch Rexroth 1MB product line. 1MB motors are high-speed asynchronous motors that can deliver up to 875 Nm rated torque and speeds of up to 20,000 RPM. 1MB motor features include large spindle cutoff and excellent running smoothness. 1MB motors can be easily integrated into machines. 1MB motors are also maintenance-free and deliver high power density. Bosch offers nine sizes for 1MB motors that can be used to satisfy a wide range of customer requirements. Typical applications for 1MB motors are main spindles of CNC machines and machining centers. The 1MR240F-A072 rotor can be used with 1MB motors that have the following type code specifications: frame length F and frame size 240. The design of the 1MR240F-A072 includes a step interference fit. The inside diameter of the rotor is 72 millimeters.

Motors that are based on the 1MR240F-A072 rotor have a maximum speed of 4000 RPM and a rated speed of 1000 RPM. The motor rated output power is 13 kilowatts. The rated current is 74 Amps and the maximum current is 164.2 Amps. The motor torque is 123 Nm. The motor dissipates 2.8 kilowatts as heat during operation. This heat is absorbed by the coolant the flows through the aluminum cooling jacket on the stator. 1MB motors are designed for 0 to 40 degrees Celsius working temperature and -20 to 80 degrees Celsius storage temperature. The maximum ambient temperature at which the motors can operate with output derating is 55 degrees Celsius. The maximum altitude at which 1MB motors can operate with output derating is 5000 meters. The weight of the 1MR240F-A072 rotor is 29 kilograms. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
