The R911286877 (MHD093C-058-NG0-RA) is a Bosch Rexroth permanent-magnet synchronous servo motor from the MHD series, designed for applications requiring precise closed-loop control. It features a continuous standstill torque of 23.0 Nm, frame length C, and motor size 093. The unit has a centering diameter of 130 mm and a flange size of 140 mm. The motor is equipped with a plain shaft and conforms to DIN 332 standards. Shaft sealing is included, and the protection rating is IP65, allowing operation in environments exposed to dust and water jets. Relative position detection is achieved via digital servo feedback (HSF) encoder. The motor cooling is by natural convection, and there is no integrated holding brake. Power connection is facilitated by a right-sided power connector.

What advantage does the shaft seal provide in the MHD093C-058-NG0-RA motor?

The shaft seal prevents contamination from dust, oil, or moisture entering the motor housing. This enhances durability and ensures consistent performance in demanding industrial environments.

Why is the power connection positioned to the right on the MHD093C-058-NG0-RA?

The right-oriented power connection simplifies cable routing and installation in tight machine assemblies. It also minimizes interference with other system components for cleaner integration.

How does the plain shaft design of the MHD093C-058-NG0-RA benefit industrial applications?

A plain shaft allows for precise coupling with external mechanical elements like gearboxes or pulleys. This ensures smooth torque transmission and reduces vibration during operation.

What is the significance of the 130 mm centering diameter in the MHD093C-058-NG0-RA?

The 130 mm centering diameter ensures accurate alignment with mating components. It enhances balance and minimizes mechanical stress on the motor bearings.

How does the short “C” motor length of the MHD093C-058-NG0-RA improve system design?

The compact “C” length design enables installation in space-constrained machinery. It helps achieve high power density without sacrificing performance or torque output.
