R911299262
The R911299262 (MHD115C-059-PP0-BA) is a high-performance product from Bosch Rexroth Indramat designed to provide efficient solutions to problems in industrial automation. This model is globally recognized for its robust operation capabilities and exceptional adaptability for continuous start-stop functions at great switching frequencies. There are two operational modes - natural convection and surface cooling - each offering distinctive operational functionalities.
During natural convection, it maintains a consistent torque of 70/80.5 Nm using a current of 82.5/95.6 A, leading to a temperature increase of 60/100-K. On the other hand, during surface cooling, it delivers a rated power of 105 Nm consuming a rated current of 123.8 A. The MHD115 synchronous motor operates with a standard speed of 4000 rpm that can max out at 6000 rpm. It includes an HSF integrated with a multi-turn optical encoder for precise rotor positioning and an optional output shaft featherkey for steady unidirectional torque. Marked with an IP65 protection standard, this motor is constructed to run efficiently even under harsh conditions. The device requires input power between 88 – 90 VAC for natural cooling mode and 175 VAC for surface cooling mode, and can produce maximum power up to 7.7 kW. It is advised to operate the machine within the recommended temperature range of 0 to +40 degrees Celsius to maintain its insulation category, class F. The motor weighs around 55 kg and includes 4 pole pairs with a winding inductivity of 0.9 mH.
