Product Description:

The MHD093B-035-NG0-RN is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Offering electronic commutation and high dynamic stiffness, it translates commanded current into precise rotary motion for point-to-point or continuous path tasks within automated cells. The unit belongs to motor size 093, length B, and is intended to be driven by Indramat digital amplifiers where tight velocity and position loops are mandatory.

At standstill the motor can deliver a continuous torque of 17.5 Nm, providing steady holding power for indexing tables and vertical axes. Its housing carries a IP65 rating, so dust ingress is blocked and water jets do not impair operation. Heat is removed through liquid cooling, which keeps the stator temperature below insulation limits during high duty cycles and allows higher continuous output than air-cooled models. Accurate mechanical alignment is simplified by the 130 mm centering diameter, and the mounting interface follows a flange pattern of 140 / 150 mm, matching common Rexroth gearboxes. Reliable operation is maintained within an ambient range of 0 to 40 °C, enabling installation on most factory floors without derating.

The position loop is closed with a digital servo feedback (HSF) encoder that measures rotor angle optically and reports it to the drive in real time. This feedback supports a system accuracy of ± 0.5 angular minutes, suitable for precise interpolated moves in pick-and-place lines. The rotor end is specified as a plain shaft, so couplers or timing pulleys can be mounted directly without keyway machining. A winding code 035 stator, insulation class F materials, a liquid-tight shaft seal, and an allowable storage temperature from −20 to +80 °C complete the environmental profile. The motor can be installed up to 1000 m above sea level, and because it is supplied without a holding brake, external locking or drive torque must secure loads when power is removed.
