Product Description:
The MHD093C-058-PG1-BA is a servo motor engineered by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a brushless AC drive element, it converts regulated current from a matching controller into precise rotary motion for positioning tables, gantries, and transfer modules in automated lines. Its internal feedback and brake hardware support closed-loop speed and position control, and the motor can hold a load securely when power is removed.
The motor can sustain 23.0 Nm of continuous torque at standstill, allowing it to support moderate static loads without overheating during standstill operation. A centering diameter of 130 mm aligns the housing concentrically with the machine frame, which helps keep coupling alignment consistent and limits unwanted vibration. Heat is removed through natural convection, so no external blower or liquid circuit is required. The mounting interface matches a flange size of 140 / 150 mm, which supports direct installation on compatible machine plates. A plain shaft transfers torque directly to couplings or pulleys without keys, and a separate shaft seal helps keep contaminants away from the bearing area.
Power enters the enclosure through an output connector oriented on side B, allowing cable routing away from moving axes and crowded machine faces. An integrated brake delivers 22.0 Nm of holding torque, keeping vertical or suspended loads stationary when the drive is disabled. Rotor angle is tracked by a digital servo feedback system that reports an absolute (>4096 revolutions) position value to the controller, so the axis can retain multi-turn position information after power-up. This feedback arrangement helps the controller restore motor position quickly and supports accurate restart behavior on indexing and transfer applications.
