R911309075
Bosch Rexroth Indramat introduces its R911309075 (MHD112B-024-NP0-LN) servo motor, a product belonging to its feature-rich MHD series. Economically viable and user-friendly, this unit boasts diverse applicability, made possible by its ability to cool naturally or via a liquid-based mechanism, depending on the configuration. Its frame length is labeled as B, and the windings are marked 112. With a weight of 34 kg and characteristic motor speed of 2000 RPM, it can reach a maximum rotation speed of 4000 RPM under ideal conditions.
The R911309075 (MHD112B-024-NP0-LN) operates within a temperature range of 0 to 40 ° C and comes equipped with a digital servo feedback encoder. Designed for efficient surface cooling and natural convection, this motor also features an insulation class of 155, allowing the operator to use it in virtually any environment. The structure includes a rotatable plug, a sealing ring, and a keyway. Delivering a theoretical max torque of 102 Nm, the rated current and torque of the motor vary, contingent upon the cooling and overtemperature conditions. It exhibits a torque constant of 1.43 Nm/A at a temperature of 20 ° C and has a thermal time constant that depends upon the cooling method and motor overtemperature. At 60K overtemperature with natural convection, its continuous standstill torque is 28.0 Nm, while its continuous current at standstill is 21.9 A.
