Product Description:

The MHD071B-061-NP0-UN is a permanent-magnet AC motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is intended to generate controlled shaft torque for servo axes in industrial automation equipment such as handling robots, feeders, and processing machinery, where repeatable speed and position regulation are required. The motor works with digital drive controllers and supports compact machine layouts through an integrated feedback and power connector arrangement. Its synchronous design supports accurate motion control during repeated start, stop, and positioning cycles.

The mechanical interface uses a centering diameter of 95 mm and a square mounting flange that measures 115 mm. These dimensions position the motor concentrically on the machine face and provide a consistent bolt pattern for mounting. At standstill, the motor can produce a continuous torque of 8.0 Nm, providing steady holding force without thermal overload when it is paired with the intended cooling method. Heat is removed by liquid cooling, so thermal energy passes through the housing jacket instead of relying on ambient air. Output torque is transferred through a keyed shaft, which supports standard couplings and helps prevent rotational slip under load.

The power plug can be rotated through 270°, which helps route cabling without placing unnecessary stress on the conductors. Position data reaches the drive through digital servo feedback (HSF), and because the feedback is relative, the axis requires a homing cycle after power is applied. Winding code 061 identifies the electrical configuration used for this motor. The motor size of 071 with length B keeps the package compact for space-limited machine layouts. A single pair of power and feedback connectors also reduces external connection points and helps preserve the housing seal.
