Product Description:

The MHD071A-061-NG0-UN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It transforms electrical energy from a drive controller into controlled rotary motion, allowing precise positioning or speed regulation on automated packaging, pick-and-place, and materials-handling stations. By serving as the electromechanical actuator in multi-axis assemblies, it links the control architecture to the mechanical load and supports continuous operation in demanding industrial automation environments.

This model seats against the machine frame with a centering diameter of 95 mm, keeping the stator coaxial with the driven mechanics. Its continuous torque at standstill is 3.5 Nm, so it can hold static loads without exceeding thermal limits when the axis is locked. The mounting flange measures 115 mm, matching standardized bolt patterns for medium-frame equipment. Rotor position is reported through a digital servo feedback (HSF) encoder that delivers high-speed incremental data for closed-loop control. Thermal energy is extracted through liquid cooling; an internal jacket carries coolant past the windings so rated output is maintained even when the motor is sealed inside a cabinet. Additional characteristics include motor size 071, the compact A-length housing, a relative position detection scheme, and the absence of a holding brake, which shifts static-holding responsibility to the drive torque or external locks.

A plain shaft accepts clamp couplings or shrink-fit pulleys where low backlash is required. The power connector can be oriented within a 270° range, so the cable can be routed away from nearby components after the motor is bolted down. There is a shaft seal that restricts coolant, oil, and dust ingress into the bearing cavity during wash-down or dusty operation. Electrical behavior is matched to the drive by winding code 061, which sets the phase resistance and inductance appropriate for the specified supply voltage and current envelope.
