Product Description:

The MHD093B-035-PG1-AN/S020 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. It converts three-phase electrical power into commanded rotary motion for industrial gantries, machine tools, and packaging stations. Absolute position data is produced by a digital servo feedback device that relies on an optical measurement method. A plain shaft, a power interface routed to side A through an output connector, and the 035 winding code round out the mechanical and electrical identity of the unit.

The motor delivers a continuous standstill torque of 17.5 Nm, enabling static axis holding without excess heating. Protection is classified at IP65, so the enclosure resists dust ingress and low-pressure water jets common in production environments. Heat is removed through liquid cooling, which permits higher power density than surface-cooled frames. System accuracy is ± 0.5 angular minutes, supporting tight contour tolerances. An integrated holding brake provides 22.0 Nm of locking torque to secure vertical loads during power-off events. The operating ambient range of 0 to 40 °C allows full ratings, while a separate storage range of -20 to +80 °C protects materials when the machine is idle.

A centering diameter of 130 mm aligns the B-length, size 093 housing with mounting flanges sized 140 / 150 mm and keeps the shaft concentric to coupled mechanics. Windings are insulated to class F, allowing winding temperatures up to 155 °C over extended duty cycles. The motor uses an absolute encoder with more than 4096 revolutions, which eliminates the need for homing after power loss and supports the noted system accuracy at a maximum installation altitude of 1000 m MSL. A shaft seal is fitted for oil-mist environments, and the output connector design provides a direct power connection.
