The R911287363 (MHD093C-058-NP0-AA) is a Bosch Rexroth MHD synchronous servo motor with frame size 093, length C, and winding code 058. It features a 130 mm centering diameter, 140 mm flange size, and a 32 mm keyed shaft with a seal. The unit is flange-mounted via four 11 mm holes and does not include a holding brake. It uses natural convection for cooling and a digital servo feedback (HSF) encoder for relative position detection. The continuous stall torque is 23.0 Nm, with a peak current of 127.4 A and peak theoretical torque of 88 Nm. The enclosure is IP65-rated and supports operating temperatures from 0 to 40°C. Power connection is via an output connector on side A and the encoder connector is rotatable.

Frequently Asked Questions

Does the MHD093C-058-NP0-AA motor benefit from having its power connection on side A?

Yes, having the power connection on side A simplifies wiring and installation in tight spaces. It also minimizes cable stress and potential signal interference during operation.

How does the keyed shaft design improve the functionality of the MHD093C-058-NP0-AA?

The keyed shaft provides a secure mechanical connection to the driven component, preventing slippage. This design ensures reliable torque transmission under high-load conditions.

Why does the MHD093C-058-NP0-AA use relative position detection instead of absolute?

Relative detection offers a simpler and cost-effective setup while maintaining precise control. It’s ideal for systems that can perform homing or reference runs at startup.

Do shaft seals on the MHD093C-058-NP0-AA motor contribute to long-term durability?

Yes, the shaft seal prevents dust, moisture, and oil ingress into the motor housing. This protection extends the motor’s operational life, especially in harsh industrial settings.

How does natural convection cooling improve the operation of the MHD093C-058-NP0-AA?

Natural convection enables silent and maintenance-free temperature regulation without extra fans. This makes it suitable for clean or noise-sensitive applications.
