Product Description:

The MHD093B-058-PG1-BN is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Designed for closed-loop positioning in automated machine axes, the unit converts electrical drive commands into controlled mechanical rotation through its integrated encoder feedback. In packaging, handling, or machining cells, the motor couples directly to gearboxes or load shafts to deliver precise motion profiles that synchronize with the system controller.

Its continuous stall capability reaches 17.5 Nm, meaning the rotor can hold that torque indefinitely without exceeding thermal limits. To remove the heat generated at this rating, the stator housing uses liquid cooling, which keeps the winding temperature stable during prolonged heavy duty cycles. The motor is rated to IP65, so internal components resist dust and low-pressure water jets encountered on factory floors. The mounting pilot follows a 130 mm centering diameter, allowing repeatable alignment against standardized 140/150 mm flanges. Electrical insulation and magnetic performance remain valid within an ambient range of 0 to 40 °C, permitting installation on machines operating in normal plant climates.

During power-off states, a built-in brake supplies 22.0 Nm of static torque to keep vertical or suspended loads from drifting. Position feedback is delivered through digital servo electronics that use an optical measuring method with absolute resolution over more than 4,096 revolutions, and this configuration attains a system accuracy of ± 0.5 angular minutes. This feedback arrangement lets controllers resume motion sequences without homing routines after power is restored. Windings use Class F insulation to tolerate elevated internal temperatures produced by fast accelerations, while the plain-shaft design, shaft seal, and side-B power connector simplify coupling and cable routing inside compact multi-axis frames.
