MHD115B-058-PP1-AN

The MHD115B-058-PP1-AN from Bosch Rexroth Indramat's MHD Synchronous Motors series is a high-performance servo motor designed for demanding industrial motion control applications. This Product Type features a Motor Size of 115, a keyed Shaft Design, and a robust Shaft Seal to ensure durability in harsh environments. Engineered with a Winding Code of 058, the motor housing measures Flange size 192 mm and a Centering diameter of 180 mm for precise integration into modular drive systems. The compact design utilizes a Motor Length variant B to balance torque output with installation envelope constraints. Equipped with a sealed housing and side-A power interface, it supports both natural convection and advanced liquid cooling strategies. With an approximate shipping weight of 40 kg (including a 3.8 kg brake assembly), it offers an optimal power-to-weight ratio for high-inertia loads.

Performance is driven by a Continuous Torque at Standstill of 50 Nm, complemented by a Holding Brake Torque of 70 Nm for secure load retention when idle. The integrated digital servo feedback encoder delivers absolute position detection across >4096 revolutions and is housed within a Encoder Type module for reliable closed-loop control. Cooling performance is managed via the configurable Housing Cooling Type, enabling up to 56.4 Nm at 49.6 A with liquid cooling and maintaining peak output of 28.6 kW at 4000 rpm. When operated under natural convection, the motor delivers 33.8 Nm at 30 A (6.6 kW) at 100 K overtemperature or 17 Nm at 15 A (3.2 kW) at 60 K overtemperature. Power connection is facilitated by an output Power Connection Type on Power Connection Direction side A, ensuring straightforward integration with Rexroth drive electronics. The combination of high torque density, precision encoding, and versatile cooling makes it ideal for dynamic positioning tasks.

Reliability is maximized through a fully sealed housing and integrated Shaft Seal, safeguarding internal components against dust and moisture ingress. The built-in 70 Nm holding brake provides immediate mechanical locking for emergency stops and power-loss scenarios. With a rugged construction and compatibility with standard drive modules, this motor seamlessly integrates into modular automation architectures. It is well suited for industrial robotics, CNC machining centers, packaging machinery, and any application requiring precise, repeatable motion under continuous loads. The MHD115B-058-PP1-AN ensures consistent performance over a wide temperature range and long service intervals, supporting optimal uptime in critical manufacturing processes.
