Product Description:

The MHD071A-061-NP0-UN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. It is intended for positioning and velocity control tasks across automated assembly, packaging, and material-handling equipment. When coupled to a matching drive controller, the motor converts electrical setpoints into mechanical rotation with high repeatability, providing a core actuation element inside industrial automation cells. Its synchronous design supports controlled acceleration, stable low-speed motion, and repeatable stopping behavior on servo-driven axes.

This model follows size code 071 and length A, giving a compact stator body. The mounting interface uses a 115 mm square flange, and a centering diameter of 95 mm provides concentric alignment against the machine face. At standstill, the rotor can deliver a continuous torque of 3.5 Nm, allowing stable force output for holding or slow-speed feed moves. Heat generated in the windings is removed through liquid cooling, which helps carry thermal losses away without relying on external fans. Power is transmitted through a keyed shaft, and rotor position is monitored by a digital servo feedback encoder. The motor is supplied without a holding brake, so external clamping must be used when passive load locking is required.

Electrical connections are made with combined power and feedback connectors, and the power plug is turnable within 270° to simplify cable layout inside a tight cabinet. A shaft seal is present to limit lubricant escape and contaminant ingress at the drive end. The electromagnetic package is identified by winding code 061, which indicates resistance and inductance values used by matching Indramat drives. Position reporting is Relative, so the axis needs a reference move after power-up before absolute position is available. This connector arrangement helps keep the connection area compact when cables must pass around guards, frames, or adjacent axes.
