Product Description:

The MHD071B-035-NP2-UN is a servo motor in the MHD Synchronous Motors series from Bosch Rexroth Indramat. It provides position-controlled rotary motion for axis drives in automated machinery and works with digital drive controllers for closed-loop motion tasks. This arrangement supports accurate positioning and repeatable response in packaging, handling, and similar equipment. The design also suits machines that need sealed electrical cabinets while still allowing flexible connector orientation to fit different layout constraints.

The motor delivers a continuous standstill torque of 8.0 Nm, giving stable holding force during static or low-speed operation. Its housing has an IP65 rating that blocks dust ingress and protects against water jets, which is useful on production floors where washdowns are common. Mounting is provided by an IEC-compliant flange that measures 115 mm across and supports secure installation on standard machine interfaces. Rotor position is monitored through digital servo feedback (HSF), which uses high-speed optical scanning of an internal code disk to send real-time incremental data to the drive. Heat generated by copper losses is removed through liquid cooling, which helps maintain winding temperature under continuous load and supports enclosed cabinet layouts.

An integrated holding brake provides 6.5 Nm of static torque so the shaft can remain locked when power is removed. Rated operation is permitted in ambient temperatures of 0 to 40 °C, which matches typical indoor industrial conditions. System accuracy is listed as ± 0.5 angular minutes, helping multi-axis gantries maintain positional tolerance without external encoders. A centering diameter of 95 mm helps align the stator on the machine plate and reduce radial runout during installation. The motor also has a keyed shaft for positive mechanical coupling and a shaft seal that helps block coolant mist. Turnable power connectors can be adjusted through 270 degrees, and the unit uses F-class insulation for operation at elevations up to 1000 m above mean sea level.
