Product Description:

The MHD115B-059-NG0-AA belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a servo motor, it converts controlled electrical input into precise mechanical rotation for positioning and velocity tasks on packaging lines, gantry axes, and similar automation stations. When paired with a compatible drive, it supports accurate motion control during repeated starts, stops, and speed changes on automated equipment.

This model can hold a continuous standstill torque of 50.0 Nm, allowing it to support static loads without external gearing. The centering pilot on the mounting face measures 180 mm, which aligns the housing concentrically to the driven machine. A flange size of 192 mm provides a broad bolt pattern for stable installation. Rotor position is reported by a digital servo feedback encoder using the HSF protocol, enabling high-speed closed-loop control. Heat generated in the stator is removed through natural convection, so no external blower or liquid circuit is required. Mechanical energy reaches the load through a plain shaft, allowing the motor to be coupled to precision gearboxes or timing pulleys. The unit is delivered without a holding brake, so static parking torque must be supplied by the drive or by an external clamp.

Motor length code B balances inertia and power density within size 115 stator laminations, while winding code 059 matches the electrical characteristics used by standard Indramat drives. Power is connected through a connector on side A, which helps with cable routing when space behind the motor is limited. Relative position detection suits applications that home during startup and then track position through incremental counts during operation. A shaft seal is fitted at the output end to help block fine dust from entering the bearing area and to reduce the escape of lubricant under normal ambient conditions.
