Product Description:

The MHD112B-024-NP0-LN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a rotary actuator, it converts electrical energy from a drive controller into controlled mechanical motion for positioning axes, transport modules, or process tools in automated equipment. When paired with a compatible controller, it supports regulated torque, speed, and position control during repeated motion cycles. Its design is intended for applications that require stable operation, accurate feedback, and dependable thermal performance over extended duty periods.

The motor’s centering feature measures 130 mm, giving the machine a fixed pilot diameter for locating the housing in a register bore. A continuous standstill torque of 28.0 Nm allows the shaft to hold commanded loads at zero speed under closed-loop control. Heat produced in the windings is removed by liquid cooling, with coolant flowing through internal channels to keep stator temperature within normal operating limits during extended duty cycles. Mechanical power is transferred through a keyed shaft, which helps prevent slippage between the shaft and the coupled element. Electrical supply conductors terminate on a sealed power connector, which keeps the connection enclosed and separates live parts from the surrounding workspace.

Positional data come from a digital servo feedback (HSF) encoder that reports incremental counts to the drive and supports the motor’s relative detection method. A mounting flange of 192 mm matches common square mounting patterns used on many index tables and gearboxes. Because the unit is supplied without a holding brake, any power-off load retention must be managed by external clamping devices or by the drive’s static torque. A dedicated shaft seal blocks lubricant migration and limits dust or coolant ingress along the output shaft. This arrangement helps the motor remain suitable for installations where fluid exposure or fine particulates are present around the drive end.
