Product Description:

The MHD115A-024-PP0-AA is manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. As a servo motor, it supplies closed-loop rotary motion for industrial positioning tasks and feeds real-time rotor data to the drive for precise velocity and torque regulation within automated machinery. This makes it suitable for axes that must start and stop frequently, maintain stable speed under changing load, and follow commanded positions with consistent response.

This model delivers a continuous standstill torque of 32.0 Nm, allowing it to hold load without overheating. Mechanical alignment to the driven equipment is simplified by a 180 mm centering diameter and a 192 mm square flange that matches standard mounting patterns. Protection against dust and water jets is rated at IP65, while cooling is handled by natural convection, so no external fan is required. The output shaft is keyed and sealed, and the motor has no holding brake, so external locking devices must be used for power-off retention on vertical or load-sensitive axes. Power is routed to side A through an output connector, which keeps cabling on one face of the machine and can simplify routing in compact installations. Position feedback relies on digital servo feedback from an integrated optical encoder, so the drive receives rotor data with minimal latency during acceleration, deceleration, and holding.

The motor operates in ambient temperatures from 0 to 40 °C and can be stored between -20 and +80 °C without damage. Its insulation system is class F, which supports winding temperatures up to 155 °C during normal thermal loading. System accuracy reaches ± 0.5 angular minutes, and an absolute measuring system tracks position across multiple shaft turns with more than 4096 revolutions of range. This feedback arrangement allows the controller to retain position information over repeated turns instead of relying only on single-revolution data. The motor uses size 115 hardware with length A, which keeps the overall envelope compact. It can be installed up to 1000 m above mean sea level without derating, and the keyed rotor follows winding code 024 so the drive can match the motor to the intended load profile.
