Product Description:

The MHD115C-024-NG0-LA servo motor is manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is used in industrial automation axes where precise rotary motion is required from a compact electromechanical drive. A high-speed digital servo feedback encoder with optical sensing supplies relative rotor position to the controller, allowing tight velocity and torque regulation during operation. This arrangement supports repeatable motion in handling, packaging, and other automated systems that depend on accurate speed and position control.

This model can supply a continuous standstill torque of 70.0 Nm, which indicates the load it can hold at zero speed without overheating. Its enclosure carries an IP65 rating, so internal components are protected from dust and low-pressure water jets. Mechanical centering is provided by a 180 mm pilot diameter, and the mounting flange measures 192 mm, providing a clear reference for spindle or gearhead alignment. Cooling relies on natural convection through the ribbed housing, eliminating the need for forced air in cabinets with limited airflow. A plain shaft with an integral shaft seal helps prevent lubricant loss and contaminant entry when the motor is coupled to external mechanics. The power lead exits on the left through a locking power connector, which can simplify cable routing in compact machine frames. Rated operation is allowed from 0 to 40 °C, matching common production-floor conditions.

Electrical behavior is identified by winding code 024, which matches the motor to compatible drive modules for its current and voltage demand. Class F insulation permits winding temperatures up to 155 °C during heavy cycles without dielectric breakdown. Closed-loop accuracy reaches ± 0.5 angular minutes, based on the optical measuring system used for relative position detection. The unit tolerates storage and transport conditions of -20 to +80 °C, and it may be mounted up to 1000 m above mean sea level without derating. Because it is supplied without a holding brake, the axis must rely on drive torque or an external locking device when power is removed. This combination supports accurate positioning in indexing, feed, and servo-controlled transfer applications.
