Product Description:

Bosch Rexroth Indramat's MHD093A-058-PP0-AA belongs to the MHD Synchronous Motors series and is a servo motor for position-controlled automation axes. In service, it converts drive commands into controlled rotary motion for machine axes that require accurate speed and position response. It uses winding code 058 in size 093 with the short A motor length. Power is routed through an output connector on side A, and torque is transmitted through a keyed shaft with a shaft seal. Cooling relies on natural convection, and the unit is supplied without a holding brake.

The stator can deliver a continuous standstill torque of 12.0 Nm, and the housing is rated IP65, which helps keep dust and low-pressure water jets away from internal parts. Mechanical centering is aided by a 130 mm centering diameter, and the mounting flange matches 140 / 150 mm bolt patterns. Rotor position is captured by an optical digital servo feedback encoder that supports absolute measurement beyond 4096 revolutions, giving the system an accuracy of ± 0.5 angular minutes. This multi-turn feedback lets the drive track shaft position over many rotations without losing the absolute reference. The optically scanned code disk avoids contact wear and supports fast homing. Position data are transferred as absolute values, so the drive can retain position information after power interruptions.

The motor operates in ambient temperatures from 0 to 40 °C and can be stored from −20 to +80 °C. Insulation class F allows winding temperatures up to 155 °C during operation and supports repeated load cycles. Installation is permitted up to 1000 m above sea level, where the lower air density does not interfere with natural convection. The listed ambient and storage ranges set the acceptable temperature window for energized operation and non-operating transport or warehousing.
