Product Description:
The MHD093B-024-NG1-BA is a servo motor from Bosch Rexroth Indramat in the MHD Synchronous Motors series. With a motor size of 093 and length code B, the unit fits a mid-frame envelope suited to medium-inertia loads on automated production lines. As a servo motor, it converts drive current into controlled rotary motion for positioning axes, conveyors, and tool spindles. This design is intended for closed-loop applications where speed and position must remain stable when load conditions change during operation. It is commonly used where accurate synchronization between the motor and the controller is necessary for repeatable machine motion.
The motor can supply a continuous standstill torque of 17.5 Nm, allowing the axis to hold load at zero speed without overheating. An integrated holding brake secures the shaft with 22.0 Nm of torque for holding and stopping functions when required. Rotor position is reported through digital servo feedback (HSF), which sends high-resolution incremental signals to the drive controller for responsive current and speed control. This feedback method allows the drive to monitor rotor movement continuously and maintain smooth response during acceleration, deceleration, and low-speed positioning. A mounting flange of 140 / 150 mm and a centering diameter of 130 mm align the housing accurately to connected machine parts and help limit radial runout.
Thermal management relies on natural convection, so no external blower or liquid circuit is required and heat dissipates through the ribbed stator frame. The motor uses a plain shaft with a shaft seal, which supports direct coupling to gears or pulleys while helping block lubricant ingress and contamination near the bearings. Winding code 024 identifies the stator winding used with matching inverter voltage and current ranges, and power conductors exit on side B through an output connector to simplify cable routing. Feedback lines can be routed with the power cable path to keep the motor connection layout compact. The unit uses relative position detection, so the controller must run a homing routine after each power cycle before absolute machine coordinates are available.
