MHD093C-058-PG2-AA
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD093C-058-PG2-AA from the MHD Synchronous Motors series is a high-precision Product Type servo motor engineered for demanding automation tasks. This Motor Size 093 frame features a compact Motor Length C design with a robust Winding Code 058 stator winding. A dual-diameter host interface of Centering diameter 130 mm and selectable Flange size 140 / 150 mm ensures versatile mounting options across machine tool and robotics platforms. Its Protection rating IP65 housing offers dust-tight integrity and splash resistance for extended uptime.
With an available Holding Brake rated at Holding Brake Torque 32.0 Nm, the MHD093C-058-PG2-AA maintains rotor position during power-off, while providing a Continuous Torque at Standstill 23.0 Nm for holding applications. Motion feedback comes from a Digital servo feedback w/ integrated encoder that supports Absolute (>4096 revolutions) position detection for high repeatability. The motor employs a Housing Cooling Type natural convection system, allowing operation in ambient temperatures up to Max temperature 40 °C without additional auxiliaries. Internal seals and plain-shaft construction deliver reliable performance in both cleanroom and industrial environments.
Connectivity is simplified via an Output Connector power interface positioned to side A, streamlining cable routing in tight cabinet layouts. The Shaft Design plain shaft with integrated Shaft Seal resists ingress and facilitates direct-coupling to brakes, clutches, or gearboxes. Constructed as a Motor type synchronous servo motor, the MHD093C-058-PG2-AA balances high torque density with low inertia for dynamic response and precise trajectory control.

Frequently Asked Questions
What benefit does the IP65 protection rating provide for the MHD093C-058-PG2-AA?
It ensures complete dust protection and resistance to low-pressure water jets, making the motor suitable for harsh industrial conditions.
Why is the digital servo feedback system essential in the MHD093C-058-PG2-AA?
Its integrated digital encoder ensures high-resolution absolute position detection, enhancing precision and eliminating the need for homing after power loss.
How does the plain-shaft design with a shaft seal contribute to the MHD093C-058-PG2-AA’s durability?
The plain-shaft structure with a protective seal prevents lubricant loss and contamination ingress, extending service life in dusty or humid environments.
Why is low rotor inertia valuable in the MHD093C-058-PG2-AA for automation systems?
Low inertia allows rapid acceleration and deceleration, improving the system’s dynamic response and enabling precise motion control in high-speed applications.
How does the dual-diameter flange design of the MHD093C-058-PG2-AA improve installation flexibility?
The dual 140/150 mm flange allows the motor to fit various mechanical interfaces without adapter plates. This versatility reduces setup time and enables integration across different machine platforms.
