The R911289961 (MHD115C-058-NP1-BA) is a top-notch model from Bosch Rexroth's MHD series of permanent-magnet synchronous motors. Specifically designed to power automation systems, it finds typical use in machine tools, paper processing, printing machines, handling/automation systems, and food processing or packaging. With a flange size of 192mm and a centering diameter of 180mm, this maintenance-free model features a brushless design and is completely sealed for protection against dust, liquids and contact. Its lifetime lubricated bearings give it a service life of 10,000 hours. The motor has a holding brake with a torque of 70Nm and is convection and surface cooled. The heartbeat of this resilient workhorse is its rotor with 4 pole pairs and a high torque to inertia mass ratio that makes it ideal for high-dynamic operations. The motor can reach up to 6,000 rpm and delivers a theoretical maximum torque of 231 Nm.
