Product Description

Bosch Rexroth manufactures several world-class models of servo motors, many of which are used to build different kinds of automation systems. It is the designer of the innovative MHD series of motors which are combined with Indramat drive controllers to obtain highly efficient rapid-response automation systems. The permanent-magnet synchronous servo motors are characterized by high operational reliability and high-performance data.

The MHD112D-027-NP0-RN is a servo motor in the MHD series of synchronous motors by Bosch Rexroth. This motor has a flange size of 192mm and a centering diameter of 130mm. It is equipped with inbuilt thermal sensors that prevent harmful thermal overload conditions and has a high overload capability. This quality is due to the efficient heat transfer mechanism from the stator windings of the motor to its housing walls. Based on the design of its housing, it can be cooled by natural convection or surface cooling. This housing has an IP 65 Ingress Protection rating and is resistant to dust and solid extrinsic objects. It is also safe from sprays from water jets due to its completely closed design.

The maximum speed of the MHD112D-027-NP0-RN is 3,000 revolutions per minute, while its rotor has a moment of inertia of 350x 10^-4 kgm². Its motor feedback type is digital servo feedback, and it detects the relative indirect position of the motor. It has a system accuracy of ±0.5 angular minutes and operates with the optical measuring principle. Its data memory enhances the motor’s quick startup. A shaft with a shaft sealing ring and a keyway according to DIN 6885-1 is the output shaft built into this MHD motor model. The shaft allows keyed torque transmission with a constant direction.
