R911291669
Produced by Bosch Rexroth Indramat, the R911291669 (MHD115C-059-NG0-BN) is an MHD synchronous motor built for use with its drive controllers. The motor employs a brushless design, supplemented by grease-lubricated bearings, optimizing it for maintenance-free operation. It features a built-in temperature sensor to safeguard against thermal overload. The R911291669 (MHD115C-059-NG0-BN) motor is marked by high dynamics due to an effective torque to inertia ratio, reaching maximum torque across a wide speed range up to 6,000 revs per minute, and housing four pole pairs. This motor's electrical output data is determined by its 059 winding code and 115 frame and flange size of 192 mm with a centering diameter of 180 mm.
The R911291669 (MHD115C-059-NG0-BN) boasts dual heat dissipation methods, utilizing natural convection into ambient air and augmented with liquid cooling under heavy loads or higher repeat frequencies. The motor's plain shaft design provides an efficient frictionless connection ensuring smooth operation, while its enhanced bearing weight caters to increased loads, facilitating the installation of pinions and belt pulleys. The servo motor is designed for easy start-up, attributed to the integrated digital servo feedback motor encoder's memory-stored information. Moreover, the motor's closed design and IP 65 protection rating make it resilient to challenging environmental conditions, protecting it from water jet, fluid, and solid object damage.
