Product Description:

The MHD093B-058-PP0-AA belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. As a servo motor, it provides closed-loop rotary motion for positioning axes and speed-controlled spindles in industrial automation cells. The motor works with compatible drive controllers so that commanded torque and velocity are converted into controlled motion at the load. This arrangement supports repeatable positioning and stable speed regulation in equipment that operates through frequent starts, stops, and direction changes.

The motor can deliver a continuous standstill torque of 17.5 Nm, giving a reliable force margin for static holding or low-speed feed moves. A centering diameter of 130 mm aligns the housing to a gearbox or flange, and the mounting flange follows the ISO pattern of 140 / 150 mm so it fits standard mechanical frames. Power is transmitted through a keyed shaft, which helps prevent hub slip during acceleration. Heat from the 058 winding is removed by natural convection, so no fan is required. The unit is supplied without a holding brake, which reduces inertia for applications that use an external holding method. Size code 093 and length code B set the body dimensions, while the power leads exit on side A through an angled connector. A shaft seal is installed to help limit dust and oil ingress during continuous duty.

The integrated encoder uses digital servo feedback, allowing the drive to read rotor position with high precision. Position information is retained through absolute multiturn operation of more than 4096 revolutions, so the axis can restart without a homing cycle after power is restored. Phase conductors connect through an output connector, so wiring remains straightforward and no terminal tightening is required. The encoder and connector arrangement also helps keep cable routing compact around the motor. Winding code 058 matches the stator resistance and inductance to compatible power modules, helping keep current ripple low during rapid motion profiles.
