Product Description:

The MHD131D-024-PG0-AN is a servo motor from Bosch Rexroth Indramat in the MHD Synchronous Motors series. It converts electrical power into controllable rotary motion for positioning or process axes in industrial automation. In automated equipment, it supports repeatable speed and position control on axes that require steady torque response and compact integration with a matching drive.

Beneath its cast housing, the motor can deliver a continuous standstill torque of 160 Nm, which is the constant load it can hold without overheating. Protection against dust and water jets is rated at IP65, and heat is removed by a liquid cooling jacket that helps stabilize winding temperature under cyclic duty. The mechanical interface is centered by a 250 mm pilot diameter, while a 260 mm square flange helps distribute load to the machine frame. Position feedback is generated optically by an integrated digital encoder that supports absolute measurement over more than 4096 revolutions and offers a system accuracy of ± 0.5 angular minutes. A plain shaft with a factory-installed seal helps prevent lubricant escape, and the power leads exit on side A through an output connector to simplify cable routing. The motor has size 131 with length code D for high-torque installations.

The electrical design uses winding code 024, which is matched to compatible drives for the required current and voltage limits. Safe operation is permitted at ambient temperatures of 0 to 40 °C, with storage allowed from −20 °C to 80 °C for transport and warehousing. Installation sites may be located up to 1000 m above mean sea level before derating is required. With insulation class F, the winding can tolerate internal temperatures up to 155 °C in intermittent service. The motor is supplied without a holding brake, so any static load retention must be handled by external mechanics or by the drive.
