Product Description:

Bosch Rexroth Indramat manufactures the MHD071B-061-NG2-UP as part of the MHD Synchronous Motors series. This servo motor is built for closed-loop industrial axes where precise torque and position control are required. It uses a 95 mm centering diameter with a plain shaft, so it can mount directly to geared or belt-driven loads. The feedback system supports coordinated axis motion in automated equipment that requires accurate positioning and repeatable movement.

The motor delivers a continuous standstill torque of 8.0 Nm, allowing stable holding and slow-speed operation without overheating. A flange size of 115 mm provides a secure mounting interface and helps keep the stator aligned under load. Its enclosure carries a protection rating of IP65, which keeps out dust and resists low-pressure water jets. Rotor position is monitored by Digital servo feedback (HSF) with optical scanning for high-resolution control. Long-term storage is permitted over a temperature span of -20 to +80 °C, which helps protect winding insulation and bearing grease during shipping or extended downtime. The power connector can be rotated through 270 degrees for flexible cable routing, and the motor uses B-length stator iron with frame height 071, winding code 061, and a shaft seal that helps block lubricant migration.

A holding brake rated at 6.5 Nm secures vertical or suspended loads when the drive is de-energized, and the unit maintains system accuracy within ± 0.5 angular minutes for interpolated motion. Class F insulation permits winding temperatures up to 155 °C during operation. The permitted ambient operating window is 0 to 40 °C, and installation is allowed up to 1000 m above sea level without derating. Relative position detection is measured optically, and the combined power and feedback connections help keep the motor assembly compact for servo amplifier systems used in packaging, printing, and material-handling machines.
