Product Description:

The MHD093B-024-NG0-AA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts controlled electrical input from a drive into regulated rotary motion, supplying the precision required for automated handling stations, gantry drives, and machining spindles. The design uses a plain shaft for backlash-free coupling, and the power lead exits through a connector on side A of the housing to simplify cable routing. This arrangement helps keep the connection area orderly and supports installation where cable direction must remain predictable in crowded machine layouts.

Mechanically, the motor supplies a continuous standstill torque of 17.5 Nm, allowing stable axis holding without auxiliary gearing. Its aluminum end bell mates with machine frames through a 140 / 150 mm flange, and precise concentricity is supported by a 130 mm centering diameter. Position information is generated by Digital servo feedback (HSF), which uses an optical measuring method and sends relative data to the controller for closed-loop motion. The housing has an IP65 rating, and heat is removed by natural convection, so no fan or liquid circuit is required. The unit is delivered without a holding brake, so external holding force is needed when power is removed. The motor has size code 093 and length code B, which indicate its overall dimensions and mass.

Electrical endurance is supported by Insulation Class F, allowing winding temperatures up to 155 °C during heavy duty cycles. The motor uses Winding Code 024, which matches the current and voltage scaling of compatible drives, while system accuracy at the load flange reaches ± 0.5 angular minutes. A shaft lip seal helps prevent lubricant migration into the housing and protects internal components from contamination. The motor operates in ambient temperatures from 0 to 40 °C and may be installed up to 1000 m above mean sea level without derating. During storage or shipment, the allowable temperature range expands to –20 °C to +80 °C to protect the encoder optics and insulation.
