Product Description:

The MHD093C-058-PG0-AA is a brushless AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. Within industrial automation, it serves as a closed-loop drive element that delivers precise torque and speed control to gantries, conveyors, and indexing tables. The motor works with Indramat digital drives to provide high-resolution position feedback and fast response in multi-axis systems. Its brushless design also supports smooth operation under changing loads and reduces wear associated with mechanical commutation.

Mechanically, the motor uses a flange with a 130 mm pilot diameter for accurate alignment against gearboxes or machine frames. Its mounting interface follows a dual square pattern of 140 / 150 mm, giving flexibility during machine installation without requiring adapter plates. At standstill, the electromagnetic system delivers a continuous torque of 23.0 Nm, allowing the shaft to support steady loads during controlled holding. Cooling is provided by natural convection, so no external blower or liquid circuit is required and heat leaves through the ribbed motor housing. The active body uses size code 093, which corresponds to the motor's frame proportions.

Internally, winding code 058 pairs the motor with compatible drive controllers that can supply the required electrical profile. Motor length code C gives the unit a longer magnetic stack to increase torque without changing shaft height. Position information comes from digital servo feedback, and the system stores an absolute count of more than 4096 revolutions, so the axis can retain position information after power cycles. Power leads exit on side A through an output connector, and the plain shaft is intended for clamping hubs or similar friction-based couplings rather than keyed elements. A shaft seal helps protect the bearing area, and because the motor is supplied without a holding brake, external hardware must secure vertical loads when power is removed.
