Product Description:
The MHD093B-035-PP0-RA is a three-phase servo motor built by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a servo actuator, it converts drive commands into precise rotary motion for positioning and velocity loops in automated machinery. It integrates an absolute encoder and a keyed output shaft so the motor can report rotor angle while coupling directly to gearboxes or load shafts in packaging lines, gantries, and transfer stations. This combination allows the drive to track position during motion and after power cycling without adding a separate external feedback device.
In continuous duty, the motor can hold a stall load of 17.5 Nm, allowing closed-loop drives to sustain static loads without overheating. Its enclosure is rated at IP65, so dust ingress and water jets do not interfere with operation on open machine frames. Heat is removed through natural convection, eliminating the need for forced-air accessories in tight cabinets. Position feedback is generated by a digital servo feedback system that uses an optical reader and absolute multi-turn memory for more than 4096 revolutions. That feedback arrangement supports stable speed regulation and accurate commutation across changing load conditions. The 035 winding code matches this frame to compatible drives that can supply the required voltage and current while remaining within class F insulation limits.
The motor uses a centering pilot of 130 mm on a 140/150 mm flange, giving axial alignment for repeatable assembly. The motor runs within an ambient range of 0 to 40 °C and may be stored between -20 and +80 °C, while installation heights up to 1000 m above sea level require no derating. Closed-loop accuracy reaches ± 0.5 angular minutes through the optical measurement method and absolute position detection. Power enters from the right-hand side through a sealed connector, and a shaft seal keeps lubrication inside the housing. The output interface is a keyed shaft, and because the motor is supplied without a holding brake, the application must provide external locking if position retention during power-off is required. The right-side connection can also simplify cable routing where the motor is mounted close to guarding or other machine elements.
