Product Description:

The MHD112B-035-NP1-AN is a synchronous servo motor produced by Bosch Rexroth Indramat and included in the MHD Synchronous Motors series. Designed for closed-loop industrial automation, it converts drive power from an electronic amplifier into controlled rotary motion that can be synchronized with demanding positioning tasks on packaging machines, gantry axes, or transfer lines. Its winding code 035 and frame length B place it in the 112-size class, balancing torque output with installation space. This operating role supports repeatable acceleration, deceleration, and position correction during changing load conditions.

At stall, the motor can deliver a continuous torque of 28.0 Nm, allowing mechanical loads to remain motionless without overheating. The enclosure carries a protection rating of IP65, so internal components are sealed against dust ingress and water jets. Heat is removed through liquid cooling, using a housing circuit that helps maintain winding temperature during high-duty cycles. A permanent-magnet holding brake contributes 22.0 Nm of static restraining force when power is removed. Accurate mechanical registration is aided by the 130 mm centering diameter, while the mounting flange measures 192 mm across. Rotor position is reported by digital servo feedback (HSF), supplying high-speed signals to the drive for rapid control loops.

The motor can operate in ambient air from 0 °C to 40 °C and is insulated to Class F, supporting permissible winding temperatures up to 155 °C. Installations up to 1000 m above MSL do not require power derating, which simplifies use at typical industrial sites. A keyed shaft transmits torque through positive mechanical engagement, and an integral shaft seal helps prevent lubricant migration along that interface. The optical measurement method, combined with relative position detection, yields a system accuracy of ±0.5 angular minutes for precise path following. Power conductors exit on side A through an output connector, keeping cabling clear of cooling lines. This arrangement helps maintain orderly cable routing in compact machine layouts.
