R911258358 (MDD090A-N-020-N2M-110GA0)

Description

The Bosch Rexroth MDD motor range hosts nine permanent magnet-excited synchronous motors, each with unique torque and speed for diverse applications. The R911258358 (MDD090A-N-020-N2M-110GA0) model has a digital servo feedback with an inclusive multiturn absolute encoder for absolute indirect position evaluation on the motor. Its encoder offers a system accuracy of ±0.5 angular minutes, making it ideal for high-precision tasks like operating in grinding machines. This MDD model, with a nominal speed of 2,000 rpm and a standard centering diameter of 110mm, employs a plain output shaft for non-positive and backlash-free torque transmission. The motor incorporates a temperature sensor to prevent thermal overload damage. It boasts high overload capability due to substantial heat conduction from the stator windings to the housing's outer wall. The brushless design and lifetime-lubricated bearings ensure a high degree of reliability and maintenance-free operation. Operating conditions include a maximum ambient temperature of 40°C, relative humidity of up to 95%, and installation height of up to 1,000m.
