MHD115A-024-PP1-AA
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD115A-024-PP1-AA servo motor from the MHD Synchronous Motors series represents a high‐performance solution for industrial motion control. This product_type features a winding code of 024 and is equipped with a robust encoder type: digital servo feedback w/ integrated encoder providing absolute position detection over Type of Position Detection: Absolute (>4096 revolutions). With a continuous torque at standstill of 32.0 Nm and a holding brake torque of 70.0 Nm, this motor delivers reliable holding capability under load. The rated voltage of 309 V and natural ambient operating range from 0 to +40 °C ensure compatibility with varied factory environments. Mechanical integration is simplified by the Motor Size: 115, flange size of 192 mm, and centering diameter of 180 mm, all designed to match standard mounting configurations.
Performance is driven by the motor’s precise electrical characteristics, including a winding resistance of 0.66 Ω and winding inductance of 8.6 mH, which support efficient current management. The MHD115A achieves a rated rotating speed of 2000 rpm in natural cooling mode at a 60 K rise, and it can accelerate to a maximum speed of 4000 rpm to generate up to maximum torque of 110 Nm. Its rotor design with keyed shaft combines high torsional stiffness with the added protection of a shaft seal to guard against contaminants. The housing employs Natural convection cooling, with a thermal time constant selectable between 30 or 60 minutes for tailored heat dissipation. Power is supplied via an Output Connector directed to side A, allowing straightforward cabling in confined machine layouts.
Reliability is assured through an IP65 protection grade housing, featuring a durable black paint coating that withstands harsh conditions and altitudes up to 1000 m above sea level. The built‐in multiturn motor encoder enables seamless position feedback without external devices, streamlining system architecture. Brake actuation and release times of 53 ms and 97 ms respectively, combined with a holding brake weight of 3.8 kg, deliver rapid response for safety and precision positioning. Installation flexibility is enhanced by universal mounting options and directional power connection adjustments. Ideal applications include CNC machining, robotics, packaging machinery, and indexing tables where the integration of the MHD Series servo motor ensures accurate, repeatable motion and extended service life.

Frequently Asked Questions
How does torque linearity affect servo motion accuracy?
The torque linearity ensures a proportional relationship between input current and mechanical output during control cycles. The consistent torque response enhances positional repeatability across varied dynamic load conditions.
Why is encoder resolution important for motion precision?
The encoder resolution defines how finely the control system interprets shaft rotation feedback. The higher count resolution minimizes error accumulation and supports smooth trajectory tracking during coordinated axis movements.
How does drive tuning influence overall system responsiveness?
The drive tuning parameters determine how quickly the control loop reacts to positional deviations. The optimized tuning settings improve stability while preventing overshoot or vibration under variable inertia conditions.
What role does motor inertia play in system integration?
The rotor inertia determines acceleration capability and mechanical resonance behavior during high-speed transitions. The correctly matched inertia ensures balanced energy transfer and prevents oscillation in servo-coupled systems.
How does temperature rise affect long-term performance?
The temperature rise within windings influences magnetic strength and insulation lifespan during continuous operation. The efficient thermal management maintains torque consistency and reduces component fatigue under repetitive duty cycles.
