MHD093B-058-PP1
The MHD093B-058-PP1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is built for closed-loop positioning tasks and is typically paired with a digital drive controller on packaging machinery, gantry axes, and material-handling modules where accurate rotary motion is required. In automated systems, it converts commanded current into controlled shaft movement so axes can accelerate, decelerate, and hold position with repeatable accuracy. This operating role suits machine sections that need stable motion at low speed as well as during rapid indexing.
At standstill the rotor can deliver 17.5 Nm continuously, which supports static loads and low-speed feed forces in positioning applications. A spring-applied, electrically released holding brake is integrated, and it can secure the shaft with up to 22.0 Nm when power is removed, helping hold the axis during stops. Mounting follows a square IEC pattern with a flange of 140 / 150 mm, while the pilot fits into a 130 mm centering diameter for repeatable alignment on gearbox or machine plates. Power is transmitted through a keyed shaft that helps prevent slip under bidirectional torque. The motor uses a B length frame, which balances torque density and thermal mass without taking up excessive installation space.
An integrated encoder supplies digital servo feedback, allowing the drive to read rotor angle directly and update current vectors on every control cycle. Position is maintained with absolute position over more than 4096 revolutions, so homing routines are unnecessary after power interruptions and stored position remains available across long travel sequences. The stator uses winding code 058, which matches the motor's electrical characteristics to compatible drive parameters in the associated control system. A positive shaft seal is fitted to limit lubricant escape and reduce contaminant entry at the coupling interface, and this feedback arrangement also supports stable commutation at low speed and during direction changes.
