Product Description:

The MHD093B-058 is a brushless AC synchronous motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for integrated drive systems, the unit converts drive-controller current into rotary motion for indexing tables, gantry axes, and packaging spindles that require accurate position control. Because torque is produced directly at the shaft, the motor supports compact machine layouts and steady motion response in applications that need repeatable starts, stops, and speed changes. This makes it suitable for axes that must reverse direction frequently without relying on bulky reduction hardware.

At standstill, the rotor can generate a continuous 17.5 Nm of torque, so the axis can hold tooling or conveyor loads without overheating. Precise machine alignment is aided by a centering pilot that measures 130 mm in diameter, giving a clear datum for concentric coupling. The square mounting flange follows a 140 / 150 mm bolt pattern, matching common modular machine plates. Internally, the stator uses winding code 058, which sets resistance, inductance, and allowable current peaks for the drive converter. Matching drive parameters to that winding helps maintain smooth acceleration and stable current control during load changes.

The motor has frame size 093, which gives an active stack length suited to a balance of inertia and acceleration. Within that frame, the housing uses length code B, which provides more copper volume than shorter versions. The product is classified as a Servo Motor, so its feedback and commutation arrangement are intended for closed-loop operation. That arrangement supports precise speed regulation and coordinated positioning when used with a compatible drive. It is part of the MHD Synchronous Motors family, and the mounting format follows the series layout used for this motor line.
