MHP115B-058-HG0-RFNNNN

The Bosch Rexroth Indramat MHP115B-058-HG0-RFNNNN motor from the MHP Synchronous Motors series features a robust Plain Shaft with Sealing Ring, an Incremental Encoder, and is Not Equipped with a Holding Brake. With 58 Windings and high-performance materials, it delivers consistent mechanical rigidity under varying loads. Designed and manufactured by Bosch Rexroth Indramat, this servo motor supports demanding industrial environments with precision. Its compact housing and balanced rotor minimise vibration, ensuring quiet, stable operation.

In terms of detailed performance, this unit achieves a Characteristic Speed of 4000 min⁻¹ and a Maximum Speed of 6000 min⁻¹, driven by a peak Current of 186.3 A. The Torque Constant of 1.33 Nm/A and Voltage Constant of 81.8 V/1000 min⁻¹ ensure rapid torque response and accurate velocity control at Nominal Frequency of 100 Hz. Its Winding Resistance of 0.11 Ω and Winding Inductance of 1.6 mH at 20 °C deliver predictable electrical characteristics for tight control loops. The motor is qualified for storage between –20 °C to +80 °C and installation at elevations up to 1000 m, enabling global deployment.

Engineers will appreciate seamless integration with Rexroth drive controllers and original plug-in connections to maintain warranty compliance. The motor’s low-inertia rotor and high winding count provide exceptional dynamic response in applications such as CNC machine tools, handling systems, and gantry axes. Built to stringent Bosch Rexroth quality standards, the MHP115B-058-HG0-RFNNNN ensures long-term reliability and minimal maintenance in continuous start-stop operations.
