Product Description:

The MHD093B-058-PG0-BA is a servo motor built by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Intended for precision motion loops on automated tooling, pick-and-place stations, and material-handling axes, it converts regulated drive current into bidirectional rotary force under closed-loop control. A compact housing combines the stator, rotor, feedback electronics, and output connector so the unit can mount directly on the machine frame. This arrangement helps keep the drive package compact while still supporting accurate positioning and repeatable speed control.

Accurate mechanical centering is provided by a 130 mm pilot diameter that supports precise flange alignment during installation. Under continuous stall conditions, the rotor delivers 17.5 Nm of torque while the winding temperature remains within its thermal limit. Heat is removed through natural convection, so no fan or liquid-cooling circuit is required. Position data is transmitted to the drive by digital servo feedback with an integrated encoder, which supports electronic commutation, speed regulation, and operating diagnostics. The motor uses a plain shaft with a shaft seal to help limit the entry of dust and oil in normal industrial service.

The front flange uses a 140 / 150 mm bolt-circle arrangement, giving the mounting face compatibility with machines that use either pattern in this frame size. Power conductors leave the stator housing through a connector on side B, which helps keep the cable path clear of the load side. The feedback system stores multi-turn position data with absolute feedback for more than 4096 revolutions, so position information is retained after power is cycled. Winding code 058 identifies the electrical characteristics used with compatible Rexroth drives. The motor is supplied without a holding brake, so any load that must remain fixed at standstill requires external holding force.
